I’m migrating an older Java backend—built on legacy Spring and Hibernate—into a fresh Spring Boot 3 project so the stack is fully modern and future-proof. The focus is code refactoring: untangling dated patterns, replacing XML configuration with annotations, adopting Spring Data JPA, and cleaning up any deprecated API usage. No new features are needed right now; the goal is pure code modernization. You’ll receive a private Git repo containing the current application and a lightweight skeleton for the new one. Work incrementally, push frequent commits, and raise pull requests so the migration stays transparent and reviewable. GitHub Actions is already wired, so every PR should keep the build green. Deliverables • A runnable Spring Boot 3.x application t...

I want a full-featured, browser-based application hosted on my own domain that delivers a growing library of word problems, logic puzzles, Sudoku-style challenges and similar brain-teasers—no arcade games, just thoughtful content. The cornerstone is a task-module system where each puzzle type lives as its own component so I can plug in new formats later without refactoring the whole codebase. Right now, the must-have variant is an image-matching task, but the architecture should anticipate text and logic modules too. For the front-end experience, I picture a clean, distraction-free panel where visitors read or view the puzzle, submit an answer, and immediately see feedback. Because I selected “User profiles with history,” registered users need personal dashboards ...
...crawls—requests that should clear in milliseconds often sit for several seconds. The rest of the app remains snappy, so we know the bottleneck lives squarely in that transaction leg. I need a performance specialist who can trace, diagnose, and remove the congestion that appears during those high-traffic windows. Whether the fix involves server-side tuning, smarter queuing, edge caching, or code-level refactoring on the mobile clients, I’m open, as long as the end result is consistent sub-second performance when users hit “Send.” You’ll have direct access to our current monitoring dashboards, API logs, and a staging environment that mirrors production load patterns. Deliverables I expect: • A concise report pinpointing the root causes of the ...
...is showing serious stability problems—unexpected pitch and roll changes that make the aircraft drift even in calm conditions. I need an engineer or developer who can dive into the existing flight-control codebase, pinpoint what is causing the instability, and implement a solid, tested fix. The job starts with a code review to isolate the root cause in the flight-control module, followed by refactoring or patching the affected algorithms (PID tuning, sensor fusion logic, or any timing issues you uncover). Once the fix is in place, I’ll need a compiled firmware image plus clear documentation of the changes so I can reproduce the build and flash future units. Acceptance criteria • Drone must hover and track waypoints without unexpected oscillation for at least 1...
I’m looking for an extra set of hands on the backend side of my project. Everything we build is written in Python and centres on clean, well-documented RESTful APIs. You’ll pick up tickets that range from adding new endpoints to refactoring existing ones for better performance, always working in a Git-based workflow and submitting pull requests for review. Day-to-day you’ll: • Implement or extend API endpoints in Python (we’re using Flask and FastAPI right now). • Write concise unit tests so every new piece of code ships with coverage. • Document each endpoint clearly in OpenAPI / Swagger so the frontend team can integrate without guesswork. Acceptance criteria for each ticket will be: the new endpoint passes automated tests, meets PEP...
...photos, rates, and availability. • Hirers browse, filter, and reach out once they see a verified badge. For this first release I’m focusing on rock-solid onboarding, profile management, and the secure verification workflow. Nice-to-haves like in-app messaging or a scheduling module can stay in the backlog for now; I just need clean hooks in the code so we can layer them on later without refactoring. Please build natively for iOS and Android (Kotlin/Swift or a cross-platform option such as Flutter or React Native—whichever you’re strongest with) and keep the backend simple but scalable; Firebase or a lightweight Node/Express API with JWT auth would be perfect. Acceptance criteria 1. Users cannot list or hire until verification is approved. 2. ...

I run an active Laravel application that must stay online while it evolves. Each day, for roughly four hours, I’ll connect you to the live VPS so you can keep the codebase healthy and push it forward without downtime. Here’s what you’ll actually be doing during those sessions: • Customising and refactoring existing modules to keep the current logic clean. • Developing brand-new features that add tangible functionality—this is the primary goal. • Jumping on any bugs or performance hiccups the moment they appear, patching them directly on the server. Although the core work is back-end Laravel, I do need someone who feels at ease handling the front-end layer—tweaking Blade templates, polishing responsive layouts and ensuring any new featur...

You’ll spend most of your time: • Tweaking and refactoring current components for cleaner, more intuitive layouts • Implementing small, incremental UI enhancements without disrupting live users • Tracking down and patching bugs as they’re reported in our issue board • Submitting concise pull requests with clear commit messages and regression tests when practical We work with a modern...
I have an existing Xamarin Forms application that already runs smoothly on iOS and Android. I now need the full codebase moved over to .NET MAUI so I can keep pace with the latest tooling and long-term platform support. While you perform the migration, I also want to introduce a handful of new features to take advantage of MAUI’s capabilities rather than simply doing a like-for-like port. Core scope The current app has about the usual mix of pages, view-models, and XAML-based UI. All functionality that works today must compile, deploy, and behave the same on iOS and Android after the upgrade, plus the agreed-upon enhancements. Any platform-specific tweaks (e.g., iOS status bar, Android permission prompts) should be handled with MAUI best practices. Key deliverables • Up...

I’m building an early-stage, web-based logistics coordination platform that must work seamlessly as a mobile-friendly Progressive Web App. The core scope includes: • Secure user authentication built around a robust email-and-password flow (the architecture should allow us to layer 2FA or social logins later without major refactoring). • Optional identity-verification hooks—please structure the code so a third-party KYC provider can be dropped in quickly once we settle on the vendor. • Payment processing that supports milestone-based escrows, releases, and refunds. • Real-time location tracking for active deliveries. • An administrative dashboard for user, payment, and task management, plus analytics. • Clean, well-documented APIs ...
...handle secure player authentication, and reliably update bet settlements with millisecond accuracy. Security is a top priority: every request and response needs advanced encryption at rest and in transit, along with strong key management and token-based auth (JWT or similar). Please structure the code so compliance additions (e.g., GDPR, local gaming regulators) can be layered in without heavy refactoring. Preferred stack is RESTful JSON over HTTPS; WebSocket streaming for live odds or spin results would be a plus. Clean Swagger / OpenAPI documentation and unit tests are mandatory so my in-house team can pick up feature work later. Deploy in Docker-ready containers; I host on AWS, so native services like API Gateway, Lambda, Aurora, or DynamoDB are familiar territory, but I&r...

Think smart refactoring, removal of unused styles or scripts, and general optimisation that keeps maintenance straightforward for our in-house team. Deliverables • All specified images integrated, properly compressed and tagged • Refactored HTML, CSS and JS pushed to our Git repo with clear commit messages • Brief change log outlining performance gains and any class/ID name changes ...
I am working with Silicon Labs’ SI4010C2 RF remotes and need reliable, well-documented SPI firmware to drive the device. Your job is to write clean, interrupt-safe C code (with concise inline comments) that initializes the SI4010C2 SPI interface, handles full-duplex transfers, and exposes a simple, reusable API so I can drop it into my existing project without major refactoring. Scope of work • Configure the SI4010C2 SPI peripheral for both master and slave use, selectable at compile time. • Provide send, receive, and combined read-write routines that support variable frame lengths. • Include a minimal example showing the code transmitting a test payload and reading it back on a logic analyzer. • Supply a short README that explains clock settings, pi...
...eased the load. Despite all that, the app still disconnects randomly throughout the day. Those interruptions halt data entry, internal messaging, and report generation—the core functions we rely on. The assignment is to trace and eliminate the root cause of the CPU spikes so the site and APK remain stable under normal traffic. An effective solution may involve query optimisation, code refactoring, queue and scheduler review, server configuration tuning, or any combination of these. Deliverables • A concise diagnostic report highlighting the exact bottlenecks (code, database, configuration, or infrastructure). • Implemented fixes committed to our repository and deployed to production. • A verification period showing 24 hours of uninterrupted upt...
...users register, track, and manage their physical payment cards from one place.

...mobiles and tablets, yet the desktop view still looks off. On the Home, About and all Product pages I’m seeing broken grid layouts and text that refuses to align where it should. I need a frontend developer who can dive into the existing HTML, CSS and vanilla-JS inside the React components, locate the root causes and ship clean fixes. That means auditing the current media-query strategy, refactoring any brittle grid or flexbox code, and correcting alignment issues so every element snaps into place across common desktop resolutions (Chrome, Firefox, Edge, Safari). Deliverables • Pixel-perfect Home, About and Product pages at ≥1280 px width • Consistent behaviour in the other breakpoints I already support (no regressions on mobile or tablet) • Up...
