I’m looking for someone who can turn a straightforward brief into a polished little desktop calculator. Python 3 and Tkinter are both must-haves because I want the finished program to run out-of-the-box on any standard installation. The look and feel should follow a classic pocket-calculator layout—nothing flashy—so users immediately recognise the keypad arrangement. Core arithmetic (add, subtract, multiply, divide) is required, and I’d like one extra: a square-root button alongside the usual operators. The buttons must also respond to keyboard input; if a user presses “7” on the keyboard, the “7” key on the interface should activate and the value should register in the display. Visual or audio effects aren’t necessary. Please build ...
I need a compact, rock-solid middleware/API that keeps fingerprint templates in our legacy MySQL database perfectly synchronized with a fleet of new Android terminals that carry X Brand sensors. The service must pull any template changes from MySQL, push them to every terminal, and confirm successful enrollment on the device side without manual intervention. Beyond the basic sync loop I also want: • real-time data validation before a template leaves the server, • detailed logging of every synchronization event, and • smart error handling that notifies me immediately if a template fails to copy, a device is offline, or any other exception appears. The stack is open: please propose the language and framework you believe will deliver low-latency performance and easy mai...
I need a complete system design and architecture for a Windows-only desktop application that will serve as a data-management solution. The core goal is to let end-users capture, organise, search and report on medium-to-large datasets through a fast, intuitive interface. Scope of work You will start from a blank slate, so the engagement covers everything from choosing the tech stack to defining the database schema, component boundaries, communication patterns and deployment strategy. While I am leaning toward a modern .NET (C#/WPF or WinUI) approach, I am open to alternative frameworks such as Electron, Qt or JavaFX if you can justify clear performance and maintainability advantages. Key activities • Draft high-level and low-level architecture diagrams (layered architecture, modu...

I need a Python-based bot that links to a technical indicator of my choice and places trades automatically on my QuoteX account. Once the indicator fires, the program must open the corresponding position, set an appropriate stop-loss and take-profit, and handle the full life-cycle of each trade without manual input. Key points I care about • Direct integration with QuoteX (web hooks, API, or reliable browser automation—whatever is most stable). • Clean Python code, well commented, so I can tweak indicator parameters later. • Logic for automatic buy/sell execution plus dynamic stop-loss and take-profit placement. • Simple configuration file (JSON, .env, or similar) where I can swap the indicator or change risk settings without touching core code. Delivera...

### Project Description: LoL Automatic Offset Finder Application **Purpose:** A desktop application that automatically finds and lists the **dynamic memory offsets** of specific entities (Unit, Missile, Summoner Spell, etc.) in League of Legends, based on the base addresses (DLL Offset) provided externally, whenever game updates (e.g., `Patch 14.1` or `` changes). #### What Exactly Should It Do? 1. **Input Data:** - The user can manually enter or read from a file the **base offsets** (e.g., `GameInstance`, `LocalPlayer`, `UnitNoClip`, `MissileList`, `MissileTarget`, etc.) that we will define or fix. - The program should find the **executable offsets** of the following main groups based on these basic offsets: - **Unit / Object Instance Address** - **Health / Max Health** - **Positio...
I need a seasoned reverse engineer who can take a deep dive into a particular video-streaming site and return with a clear, thorough explanation of how it actually works. While I want the full end-to-end picture, my main curiosity lies in the video-player layer—specifically how it performs AI-based upscaling during playback. Here is what I expect you to uncover and document: • Front-end stack in use and any frameworks that stand out. • Detailed breakdown of the video player itself—controls, custom scripts, third-party libraries, and, most importantly, the AI upscaling workflow (models employed, in-browser processing vs. server-side inference, adaptive behaviour, fall-backs). • Exact video delivery approach: HLS, DASH, WebRTC, peer-assist, or any hybrid they...

I need a small Windows-only desktop tool that sits quietly in the background, keeps an eye on a two application window, and reads any numbers or short text that appear there. Each time fresh data is detected, the script should run a mathematical calculation that I will supply (simple formula, nothing exotic). The moment the result meets my condition, I want to know right away through both a pop-up notification and a short sound. Technology-wise, I am already comfortable working with Python, so please build it in Python using screen-capture libraries such as MSS, OpenCV for basic computer-vision handling, and either PaddleOCR or Tesseract for the text recognition. The solution must continue monitoring for as long as the program is open; no browser automation or auto-clicking is involved&md...
Our ESP32-based prototype uses the MSME INNP441 digital mic, and during live audio streaming it introduces jitter and a screeching interference noise—even though the board sits in a quiet lab. I have already updated the firmware, swapped in fresh hardware, and tweaked every software register I could reach, yet the distortion persists. I’m looking for someone who can dive into the existing C/C++ (Arduino-style) code, analyse the I²S configuration and clocking, and track down whatever is corrupting the audio path. If a schematic or logic-analyser trace is helpful, I can supply both. Any fix should leave us with clean, stable voice capture that we can push straight to our streaming stack. Because this is part of our in-house tech, I will provide the full repository only a...
I’m organising a structured ten-week programme that will generate three separate mechanical engineering assignments every week, for a total of thirty tasks. Each brief will focus on one of three areas—Thermodynamics, Fluid mechanics, or Material science—so you’ll need to be comfortable switching between those disciplines as the weeks progress including physics and mathematics. I will supply the weekly problem statements on a fixed schedule; your job is to return fully worked-out solutions, complete with clear explanations, supporting calculations, and any diagrams or plots that make the reasoning easy to follow. Consistency is important, so please keep notation, units, and citation style uniform from one assignment to the next. Turnaround time is 3 days per set; t...
I need a seasoned Unreal Engine 5 developer who can build the outside-window visual system for a military-grade flight simulator. The core requirement—and my top priority—is a fully dynamic time-of-day cycle that cleanly transitions through dawn, daytime, dusk, and complete night, all in real time and fully synchronized with the simulator’s internal clock. Beyond the lighting cycle, I also want to see believable atmospheric effects: rain that streaks past the canopy, rolling banks of volumetric fog, and snowfall when conditions demand it. While combat visuals such as explosions and tracer rounds are mentioned in the broader roadmap, this first engagement is focused on nailing the day-night lighting and the three weather states listed above; we can treat ordnance effects ...
I need an expert who can dive straight into my finite-state-machine rules and tighten every transition that fires automated orders. The signals originate in TradingView, flow through our existing TS-EL strategy layer, and finally route to our TS execution servers; what’s missing is rock-solid OEX logic sequencing that calls entries and exits at precisely the right state change. Your mission is to examine the current state diagrams, rewrite or refine the conditions that trigger both entry and exit signals, and leave me with a deterministic, test-backed model that my coders can wire up without second-guessing. You should already know how to structure order-execution logic for program trading, be comfortable thinking in discrete states rather than linear indicators, and have a proven f...
I’m working with the open-source HandHeldLegend/hoja-device-fw project that targets the Raspberry Pi RP2040. I already have a short code snippet that defines a frame-perfect macro intended for gaming cheats: when the physical Y button is pressed the firmware must • hold Y for exactly 16 ms (one frame), • release it for 16 ms, • then push the Right Analog/C-Stick fully downward for another 16 ms. Nothing else in the firmware should change. What I need from you 1. Pull the repository, drop the snippet into the correct input pipeline so the macro cleanly intercepts the Y press without introducing latency or breaking other inputs. 2. Compile the project in a proven RP2040/Pico SDK environment (CMake, gcc-arm-none-eabi, etc.) and return a ready-to-flash .uf2 i...

I need a custom SCSI driver written for Linux that cleanly mounts and manages storage devices formatted with the btrfs file system. The goal is to expose full read/write functionality, pass-through standard SCSI commands, and report accurate SMART data without compromising kernel stability or btrfs’s advanced features such as snapshots and checksums. Scope • Develop a loadable kernel module that detects hot-plugged SCSI storage and registers the device so the kernel’s btrfs layer sees it as a native block device. • Implement the essential INQUIRY, READ/WRITE(10/16), MODE SENSE/SELECT, and REQUEST SENSE command set, plus TRIM/UNMAP for efficient space reclaim on btrfs. • Provide I/O queue management that keeps latency low and honours Linux’s blk-mq sc...
I need a compact, Linux-friendly suite of command-line utilities written in C or C++ that lets me run deep diagnostics on the following components: • RAM Memory • CPU • HDD & SSD (including low-level write/partition and speed tests) • RF-UNIT support where applicable The tools must be completely CLI-driven so they can slot into existing bash automation. For each utility I also need concise professional usage notes—syntax examples, expected output, and any kernel-module or package prerequisites—so a technician can get productive within minutes. Additional scope items: – Benchmark and stress-test options to reveal peak throughput and thermal throttling on RAM and CPU. – Sequential and random read/write tests on block devices, with sm...

I need a small but robust utility that runs on Nintendo Switch 2 and helps players squeeze the best possible performance out of their games. The core focus is performance optimisation: analysing in-game behaviour, identifying bottlenecks on the fly and applying smart tweaks so titles load faster, maintain steadier frame rates and feel more responsive. What I picture is a lightweight overlay or background service written in C/C++ (or another language supported by the official Switch 2 SDK) that: • profiles CPU, GPU and memory usage in real time, • applies dynamic setting adjustments or recommends the ideal presets, and • logs before/after metrics so users can clearly see the gains. SDK-compliant code, clean architecture, and clear developer documentation are es...
A fully-featured trainer/mod is required for WallStreet Raider that lets me play as an all-knowing market wizard. The tool must surface genuine-feeling insider intelligence well before the in-game clock delivers it, so every decision I make feels like it came straight from a confidential briefing. Core intelligence feed • Future stock and bond prices: show the exact figure or a definable range for any date I choose—next day, next month, or years out. • Company-specific insider news: mergers, scandals, earnings surprises and any other headlines hours, days or months before the game posts them. • Macro-event predictions: interest-rate moves, recessions, booms and policy shifts delivered in advance so I can position accordingly. Trading automation & alerts &...

I’m building the low-level firmware for an ARM Cortex-A microcontroller and need help closing the remaining gaps in startup code, peripheral configuration, and board-level testing. The toolchain is already in place (GCC, OpenOCD, and a J-Link probe), and the hardware boots, but several peripherals still need clean, maintainable drivers and the overall initialization sequence must be tightened for reliable production use. You’ll dive into: • Writing or refactoring C/C++ startup routines, linker scripts, and BSP code specific to this Cortex-A device • Bringing up UART, SPI, GPIO, and a high-speed interface that feeds data to an upstream processor • Tracing hard faults with JTAG/SWD and delivering concise root-cause notes so I can reproduce your findings &bul...
I need a clean, well-commented Python script that can place Equity orders on the NSE through my broker’s REST API. The program must support three order types—Market, Limit, and Stop-loss—and switch between them with a simple function call or flag. Key expectations • Handle authentication, session renewal, and basic error catching so an interrupted connection will not leave an order half-sent. • Clearly separate configuration (API keys, tokens, quantity, symbol) from the core logic so I can reuse the same code across multiple accounts. • Return the order ID and status in real time, ideally as both terminal output and a lightweight log file for later reconciliation. Deliverables 1. A single .py file (or small module set) ready to run. 2. A sho...
Ho bisogno di un bot Telegram capace di operare sulla blockchain Solana, dedicato in particolare ai meme token. Il bot deve poter: • eseguire acquisti di un determinato importo per il token scelto, con parametri modificabili tramite un'interfaccia intuitiva; • creare automaticamente un ordine di vendita quando il prezzo aumenta di una percentuale predefinita (x%) e due ordini di rebuy: uno quando il prezzo aumenta di una percentuale (y%) e uno quando diminuisce di una percentuale (z%); • annullare l'ordine opposto quando uno dei due ordini di rebuy viene eseguito, ripetendo la stessa logica sull'ultimo ordine; • permettere l'impostazione di una percentuale di token da vendere per ogni operazione (esempio: 90%), trattenendo i restanti token come sald...
I have a full pipeline of recruiter screens and HR‐focused interviews for senior Java roles and I need a trusted partner who can sit in on those calls for me. Your spoken English must be clear and confident enough to handle small talk, salary discussions, and cultural-fit questions without raising eyebrows. When recruiters ask about technical background you will lean on my profile: 7–8 years of hands-on work with Java as the primary language, plus solid exposure to C#, Python, .NET and React Native. HR conversations should naturally showcase team collaboration, communication, leadership and light people-management stories; I will provide real project scenarios and achievements you can reference. No live coding is expected on these calls, but you should be comfortable answering bro...
I already have a fully working handicapping routine for horse racing that I pieced together with Copilot, plus an older sample application that shows the exact flow and screens I want. What’s missing is a clean Windows-ready .exe so I can run the program (and share it with a few friends) without installing a full development environment. Here’s the current state: • All source files are ready to hand over, neatly commented. • Copilot can regenerate any individual factor or module on demand, so if you prefer rebuilding specific parts, that’s available. • I’m still deciding between a lightweight command-line tool and a simple GUI; I’d welcome your advice on which will compile most reliably and be easiest to maintain. Your role: 1. Review the exis...
I keep two Excel workbooks that record every parent payment for my childcare centre, yet each week I still find myself manually hunting for rising balances. I want to replace that manual check with a small Robotic Process Automation (RPA) flow that: • pulls the two spreadsheets, • tracks weekly changes in payment amounts, payment dates and outstanding debt, and • posts the results to a simple dashboard so I can spot any increase at a glance. What I need from you is both the working automation and the know-how. Please build the RPA script in the tool of your choice—UiPath, Power Automate, or another mainstream platform is fine—then walk me through the setup step-by-step. A short screen-share session plus a concise reference guide (PDF or video) will be perfe...
I need a seasoned build engineer to take our Android 9 through 17 source tree and make sure every version compiles cleanly on Linux. You will audit the current Gradle/CMake tool-chain, validate the resulting binaries, trace and eliminate compiler or linker errors, and create any missing software objects required for a reproducible build. The whole process must run head-to-toe on a Linux workstation against a vanilla kernel, so familiarity with GCC, Clang, CMake, and niche tools such as QVC is essential. While the primary target is Linux, experience juggling cross-platform compilers for macOS, iOS, or Windows will help you diagnose edge-case symbols that occasionally creep in. Deliverables • A one-click script (or documented command set) that produces verified Android 9–17 imag...

I have a microcontroller-based board that will sit in the field and quietly record temperature readings from one or more digital sensors. Your job is to write the embedded firmware that pulls those readings at set intervals, time-stamps them, and stores everything persistently in a neat, easily downloadable file (CSV or similar). Core needs • Reliable polling of the attached temperature sensors (currently using a standard one-wire digital device, but code should be abstract enough to swap to I²C if required later). • Configurable sample rate—default 1 Hz but changeable over a simple serial menu or compile-time constant. • Local, non-volatile storage on the board’s microSD slot; automatic file rollover when a maximum size is reached so nothing is eve...
