我需要一款纯 C 语言编写的 Windows 插件，用来实现“无文件落地”的动态加载与远程执行。核心流程大致如下： 1. 插件启动后先扫当前进程列表，若发现属于“保护列表”的进程即立刻退出，不再继续任何操作。保护列表的具体进程名稍后给你。 2. 若环境安全，插件连到我的服务器，按指令下载 DLL 或 EXE（这两种类型都必须支持）。文件不能写入磁盘，只能在内存中完成 LoadLibrary 注入；完成后即在目标进程里运行。 3. 注入目标需随机挑选系统傀儡进程，但也要保留随时切换到我指定进程的能力，便于后期策略调整。 4. 任务完成后，插件要回传本机机器码并反馈 “成功 / 失败 + 失败原因” 这两级信息，方便我做监控。 5. 为减少逆向风险，请在检测到常见反编译器或调试器时（例如我后续会补充具体名单，当前可先将 C++ 相关工具一并考虑）直接停止下载流程。反调试、反沙箱、反分析逻辑希望能集中在一处，便于我后期更新。 交付内容 • 全部 C 源码、编译脚本及简要文档 • 64-bit 可加载版本（Debug 与 Release） • 测试用示例服务器端代码（最简即可证明下载与注入链路） • 一份注入、回传、错误处理的时序说明 验收标准 • 通过我提供的保护进程测试用例，不会误执行 • 能在指定与随机模式下正确用 LoadLibrary 注入 DLL / EXE • 无磁盘 IO 行为（Process Monitor 验证） • 机器码与执行结果返回格式符合预期 • 在检测到调试 / 反编译环境时，流程终止且无网络请求 如果你具备扎...

I need the front-end of my existing Xamarin Forms mobile app lifted into .NET MAUI while keeping the current behaviour intact and wired to the same backend services. Code should compile and run cleanly for Android, iOS using the latest stable Visual Studio and .NET tool-chain. Scope • Front-end only: all backend APIs, authentication endpoints, and notification hubs stay as they are. • Preserve every screen, navigation flow, and binding so users experience no functional regression. • During the move I also want a few targeted improvements; I’ll share mock-ups once we start, but think modernised UI components and any MAUI-native performance gains that make sense. Deliverables 1. New MAUI solution with organised project structure, clean XAML/C#, and commented ...

An existing NinjaScript BarType was written for an earlier version of NinjaTrader and now throws errors in the current NT 8 release. I need the code migrated to the latest NT 8 framework so it compiles cleanly, runs in both historical and real-time mode, and displays with the platform’s default appearance—no extra logic or custom visuals required. Deliverables • Updated C# source file (.cs) fully compatible with the latest NinjaTrader 8 build • Brief change log or inline comments highlighting what was adjusted for NT 8 • Quick installation / testing note confirming the script loads, plots, and rebuilds without compiler warnings I will provide the original source for reference immediately after project award.

I’m looking to lock in a reliable baseline schedule for an upcoming project so I can measure progress against a fixed set of dates right from day one. The focus is a project-level timeline presented as a Gantt chart, detailed enough to highlight every key milestone without drilling all the way down into individual task subtasks. Here’s what I need: • A complete Gantt chart that maps the full project duration, major phases, and clearly defined milestones (with start, finish, and baseline dates). • Logical sequencing with dependencies called out so the critical path is obvious at a glance. • A baseline saved alongside the live schedule so variance tracking is effortless later on. • Editable source file—MS Project, Excel, or another mainstream too...

I have a group of absolute beginners in Chennai who need to be taken from zero to productive developer in just 45 consecutive days. The focus is squarely on three pillars: • Building REST-style services with .NET Core Web API in C# (language version 9.0 or higher) • Writing clean, idiomatic Python 3 code that complements the back-end stack • Understanding relational data design and hands-on querying with MS SQL Server, PostgreSQL and MySQL All sessions must happen at our office, Monday to Saturday, and I want a balanced rhythm—short, concept-driven lectures immediately followed by guided lab work so the class can internalise each topic before moving on. What I expect from you 1. A day-by-day curriculum outline delivered before kick-off 2. Slide decks, sample...

• Description We have input data which is the wind speed and direction. The data consists of Recent History (input) Internal (output) Forecast (only use the regular-lat-lon-simple-level) to forecast the future: We will give you the links. Your desktop app, will use the recent history to train the model with the internal output. In realtime, your app will also read the latest file from U and V 10m to produce the latest forecast. The forecast is run every hour and will be saved into our database. We will give you the REST api to save your data. We will also need you to create a script to backtest the model. i.e. using the actual data of Jan to Dec 2024 to forecast the data of Jan 2025. The window can slide so Feb to Jan 2025 to forecast the data of Feb 2025 etc. We will also need ...

• Description The objective is to create a prototype that sends our XML string via AS4 to a destination URL. You can start with <test>dummy</test> for now, but we will test with real xml. You will need to sign with the internal private key certificate and encrypt with the external public key certificate. The other side will decrypt with their private key certificate and verify our signature with our public key certificate. We will give you the certificates. You will then listen to our URL. They will send an async message 10-15 minutes later. We will give you access to our VPS, so the DNS will be routed to the VPS. You will need to verify their signature with their public key and decrypt the message with our private key. Success metrics are that the message is successfull...

I have an Angular front-end that now needs secure Single Sign-On through Auth0. The only identity provider I want wired up at this stage is Google, and I only need to pull the user’s basic profile information once authentication succeeds. Here is what I’m expecting from you: • Configure Auth0 and my Angular project so a user can click “Sign in with Google,” be redirected to Google, grant consent, and land back in the app already authenticated. • Expose the returned ID token and profile object inside an Angular service so the rest of the app can subscribe to authentication state. • Add a simple route guard that blocks protected routes when the user is not logged in. • Include a clean logout flow that clears the session both locally and in ...

I have four Excel workbooks that I now need housed in an existing MS Access database. None of the sheets are relational at the moment, so the job is a straight import and structure clean-up rather than designing complex links. Here’s what I need from you: • Import 4 existing Excel Files into 4 tables in an existing MS Access DB (.ACCB) • Add a few basic queries so I can filter, sort and export the data quickly. • Delete bad data and duplicates The project is to be done in .net with WPF user interface. Once complete, send me the .accdb file and the brief how-to notes—that’s it. If something in the data suggests a better structure, feel free to flag it before you proceed; otherwise, a clean one-to-one migration is all I’m after.

I’ve completed the core gameplay and now need a global leaderboard that plugs cleanly into my existing Unity project. The board must fetch and display each player’s name, score, and rank in real time, and add a small country flag beside the name for quick geographic context. I’m flexible on the back-end: PlayFab, Firebase, a lightweight custom REST API—whichever you feel will scale reliably without ballooning costs is fine, as long as it supports secure score submission and simple GDPR-compliant data storage. The front-end panel should match my current UI style (Unity UI Toolkit) and work on both iOS and Android builds. Deliverables: • Fully commented C# scripts for sending, retrieving, and ordering scores • UI prefab that lists name, score, rank, and ...

We have a legacy Windows desktop application built on .NET Framework 4 that captures video from a USB webcam using and a custom wrapper WebCam_Capture.dll. The program works correctly on some machines but fails to recognize our Veho USB camera on others, even though the camera works in modern apps (Windows Camera app, browsers, online webcam testers). We need a freelancer to analyze, patch, and improve the camera handling logic so that the software consistently recognizes the camera across all machines. ⸻ Key Requirements / Skills: • Strong experience with .NET Framework 2.0–4.x and C# • Experience with DirectShow / video capture pipelines • Comfortable with Windows desktop apps (WinForms/WPF) • Experience with reverse engineering / decompiling .NET assem...

I have a single PDF that holds several hundred pages of ledger entries recorded over multiple years. Because of irregular spacing, merged columns, and stray narrative comments, the file can’t be queried, reconciled, or audited in its current form. Your task is to turn every line in that PDF into a structured dataset that I can drop straight into accounting software or run analysis on. Scope of work • Parse the PDF and capture every transaction—including dates, descriptions, reference numbers, debit / credit amounts, and running balances—without loss of detail. • Correct inconsistent number formats (e.g., minus signs, comma placement, mixed currencies) and standardise dates to ISO. • Isolate any narrative comments so they appear in a separate &ldqu...

Accuracy sits at the heart of everything I do, and I need a remote operator who can match that standard. The role centers on handling day-to-day operational tasks from wherever you are, ensuring every entry, update, or follow-through is error-free and delivered on time. You will receive clearly scoped assignments through our internal portal. For each task, I expect: • A documented workflow showing the steps you took • A final file or update that can pass a 99 % accuracy check • A brief status note highlighting any blockers you encountered and how you resolved them Consistency, confidentiality, and the ability to self-audit your work will make this collaboration run smoothly. If you thrive on precision and can commit to fast, reliable turnaround, let’s get star...

I need a GoHighLevel power-user to design and build a complete, hands-off workflow that moves every prospect from first touch through to repeat customer. The core of the project is workflow automation; email and SMS steps, conditional logic, tagging, pipeline stage updates, and internal notifications all have to fire reliably without manual intervention. Key processes to automate are lead nurturing, customer onboarding, and the follow-up sequences that close the loop after a sale. When you are done, the entire leads life cycle should live inside GHL, visible and trackable at a glance. The new workflows must connect smoothly to the external tools already in play—our CRM system, our existing email marketing platform, and our social media scheduling tool—so data stays in sync ev...

Hey, I’m looking for some help with a project related to Siege and wanted to provide a bit more detail so it’s clearer what I’m after. The game I’m referring to is Siege. What I’m mainly interested in is an ESP-style visual system. My preference would be a skeleton ESP, since that’s the style I find most useful for visualization, but a box ESP would also be acceptable if it helps keep the cost lower or simplifies the implementation. This is something I’m hoping to get fairly soon—ideally as soon as possible, but within the next week would still work if that’s more realistic. Speed is definitely appreciated, though I understand development timelines can vary. If you’re interested, it would also be great to know: What approach y...

My WPF desktop app is halfway there; the core logic is working, but the presentation layer and final polish still need attention. I already have a detailed UI specification, so you can focus on bringing the remaining screens to life in XAML, wiring them cleanly into the MVVM structure, and making the whole thing run smoothly against a SQL Server back end. Here is what still needs doing: • Implement every control, style, animation, and layout exactly as shown in the spec. • Connect views to the existing SQL-driven data layer through well-structured ViewModels, keeping bindings clean and testable. • Profile memory, rendering, and startup behaviour, then eliminate the bottlenecks so large result sets scroll without stutter. I’ll hand over the current Visual Studio ...

I’m building a single, stand-alone slot machine in Unity that feels right at home on a Las Vegas casino floor. The look must be unmistakably premium: high-resolution symbols, fluid 60 FPS reel animations, tasteful particle VFX and shader-driven light sweeps—nothing less than top-tier “high quality” visuals. The theme is classic casino, so I expect glossy chrome frames, rich reds and golds, and an authentic ambient glow that instantly says “real money gaming.” Core gameplay revolves around a solid, mathematically sound backend. I need a provably random spin engine with configurable RTP, a secure pay-table system, and a robust state manager that survives app suspends or network hiccups. Multipliers are the signature feature for this build; they must hook ...

I own the domain and want it turned into a world-class, multi-platform sports game. The same code-base (or a well-synced set of repos) needs to compile cleanly for a browser build, native mobile apps, and a desktop installer. For desktop, Windows support is essential from day one; macOS and Linux are nice-to-haves we can phase in later if your framework makes that easy. Gameplay details will be shared once we’re under NDA, but expect real-time action with a strong social layer: live leaderboards, head-to-head challenges, chat, and secure in-game wallets for virtual chips. Solid netcode, account persistence, and clean separation between client and server logic are critical acceptance points. You’re free to propose the tech stack—Unity, Unreal, HTML5 + WebGL, or any engi...

I’m looking to roll out a dedicated Android app that lets my site engineers capture everything that happens on a construction project—while they are still on-site. Core workflow The app opens to a simple dashboard where the crew can: • File a structured daily report (labour, materials, weather, notes). • Attach and annotate unlimited photos straight from the phone camera. • Create, assign, and update tasks so I can track execution in real time. What matters most to me is speed and offline reliability: if there’s no signal, data should sync automatically once the device reconnects. A clean UI that field staff can learn in minutes is critical; think big buttons, clear status indicators, and minimal typing. Tech expectations Android is manda...

I’m pushing our first title, “Crucible of Ascension,” toward a playable milestone and need a Unity-savvy gameplay programmer to make it happen. The game blends real-time arena combat with a deck-building layer, so every card you play must feel snappy, balanced, and deadly in the thick of battle. What I need right now is full game development support—someone who can dive into existing code, tighten the core combat loop, hook in card logic, and keep the frame rate buttery smooth in hectic multiplayer sessions. Expect to spend most of your time in C#, ScriptableObjects, and Unity’s input and animation systems while collaborating with our small remote team through Git and regular stand-ups. We’re moving fast (the goal is ASAP), so clean, well-documente...

My Verifone VX520 is already working fine online, but I still have to keep business running when the network goes down. I need the terminal to keep a complete, reliable record of every purchase while it is offline, then upload the data once connectivity returns. In short, I want transaction logging fully activated and tested in offline mode. If you have hands-on experience with VX520 parameter setup, EMV kernel options and the usual Verifone configuration tools (VX Manager, PC Load, or comparable utilities), you will feel right at home here. I can provide remote access to the terminal or share current parameter dumps—whatever you need to move quickly. Acceptance criteria • VX520 successfully stores each sale locally with all mandatory fields (amount, PAN mask, date/time, aut...

Due to a significant inconvenience caused by another developer who lied about their competences and in the space of 17 days of allocating the project to them, they did absolutely nothing and failed to communicate along the way, I am now having to relist this project. Please can you bid on this based on your estimate for a total development cost. I am seeking to develop a bot for C Trader using a Fair Value Gaps strategy on predominantly the 1 and 3 minute timeframe for DAX and NASDAQ which will require the conversion of an indicator from Trading View to facilitate. I initially had in mind the idea of creating it as a Trading View Pinescript strategy that could then be executed on C Trader, but as Trading View receives data in lag which can often be delayed by up to 10 secs, this would aff...

I manage a growing catalogue of finished goods and need a lightweight software solution that gives me real-time visibility of every unit on the shelf. The core requirement is straightforward: accurate tracking of stock levels—nothing more, nothing less—so I always know what’s on hand, what’s reserved, and when it’s time to replenish. To keep accounting clean and avoid double entry, the application must integrate seamlessly with my existing accounting software (QuickBooks Desktop; I can provide SDK details). No other external systems are in play right now, so the integration can stay focused and lean. Key deliverables • Desktop or web-based app that records incoming and outgoing stock for finished goods. • Two-way sync with QuickBooks: item catalo...

I need a production-ready backend that powers a multi-tenant School Management SaaS. The stack is fixed—ASP.NET Core 8 Web API with EF Core and SQL Server—so you should be completely comfortable designing clean, modular code in that environment. Core scope • Build the entire API layer only; no front-end work. • Architect true multi-tenancy from day one, separating data per school while keeping shared services efficient. • Implement rock-solid authentication and authorization, plus fine-grained role-based access control. Day-to-day users include Students, Teachers, Parents, School Admins, Platform Admins and other school-specific roles, so permissions must be both flexible and secure. • Model every major domain: school setup/configuration, student/pa...

Each week I have a narrow booking window on our club’s Northstar Technologies app and I need that tee time grabbed the instant the system opens. The script must log in automatically, choose one of our three courses based on a simple setting I can change each week, then secure a slot that falls anywhere inside a time range I provide. Your solution has to run reliably on Windows and cope gracefully with captchas, latency, or the app’s occasional hiccups. As long as it is rock-solid I’m flexible on the language and tooling you use, but I do want clear instructions for installing and scheduling it so the task fires off at the exact minute I specify. Deliverables • Source code and any auxiliary files • A short README explaining setup, configuration for cour...

I need an app that focuses solely on tracking in-game statistics so coaches, parents, and players can see how they are really performing. The core features I must have are: • Real-time recording of player points • Automatic calculation of individual and team shooting percentages • Running tally of wins and losses for each game or series Anything beyond these three items—rebounds, assists, turnovers, etc.—can stay in the backlog for a later phase, so the build should stay tight and fast. I picture a clean interface that lets me create a game, tap to credit points to a player, and then instantly shows updated percentages and the overall win/loss record. Data needs to stay stored locally when offline and sync to the cloud once connected, so I can review season...

We’re building a prototype for robot teleoperation where an operator wears a VR headset and sees the robot scene through a stereoscopic VR camera with very low latency and strong depth perception—as close to “being there” as possible. Goal Phase 1 (this project): Get a working end-to-end live stream from an existing stereoscopic VR camera to a VR headset with measurably low latency and acceptable visual quality. A custom app is fine (Unity/Unreal/native). We want something we can put on and experience. Why this is hard We care about: • Motion-to-photon latency • Stereo sync (left/right alignment) • Stable framerate + low jitter • Headset-friendly rendering (proper stereo projection / distortion handling depending on platform) ⸻ Scope (Phase...

I’m building a new mobile game and need a seasoned developer who already runs active AppLovin and Mintegral ad-network accounts. The project covers the full cycle for both Android and iOS: designing the game, writing clean code, integrating AppLovin + Mintegral ads, adding in-app purchases, and taking the build all the way through store submission and live release. Because proven experience is critical here, you must be able to walk me through your own Google Play Console or App Store Connect so I can see previous titles, growth metrics, and real-time ad performance. A minimum of five years’ hands-on mobile development is required; familiarity with Unity or a comparable cross-platform engine will make things move faster. Deliverables • Playable game (Android & iOS)...
