Daripada 65,644 ulasan, klien menilai Git Professionals 4.9 daripada 5 bintang.Bangalore based freelancers or companies only "this is monthly maintenance project" I run an education-management platform that serves students and staff through a React JS web dashboard, a React Native mobile app, and a Django (Python) API. The system is already live, yet a series of small but persistent bugs on both the apps and the website are affecting the user experience. I need a developer who can move comfortably between the frontend and backend codebases, troubleshoot issues quickly, and roll out minor feature updates without disrupting daily operations. Current pain points • Visual glitches and occasional crashes in the mobile app • UI inconsistencies and broken links on the web dashboard • Backend logic errors that create data mismatches in report...
I have a fully-built dynamic website written in Node.js and I’m ready to take it live on AWS. The codebase is clean and sitting in a private Git repository; what I need now is an engineer who can handle the end-to-end deployment and leave me with a smooth, replicable workflow. Here’s the flow I’m imagining: spin up the right AWS services (EC2 or, if you think it’s smarter, Elastic Beanstalk or ECS), configure security groups, environment variables and SSL, hook the instance to our Git repo for zero-downtime updates, then connect the domain and verify that everything scales and logs correctly. If CloudFront or an RDS instance will help performance, let’s discuss—flexibility is fine as long as the final result is fast, secure and easy for me to maintain. ...
I need a production-ready MERN application whose central feature is AI-powered image generation. The workflow is straightforward: a user authenticates, submits a prompt, and instantly receives an image created through Stability AI. Every resulting asset is saved to Cloudinary and served worldwide over its CDN. Core stack and flow • Node.js + Express expose a clean REST API for auth, prompt submission, image retrieval, and basic content management. • MongoDB Atlas stores user data, prompts, and image metadata. • React (SPA) on Firebase Hosting consumes the API and provides a sleek UI, including prompt history and responsive galleries. • The backend runs on Render; deployments must be automated from Git. Key requirements • Integrate Stability AI endpoin...
I’m midway through architecting a new system and I’d like a capable full-stack developer to pair with me day-to-day. The immediate focus is front-end development, so you’ll be steering our React and layers—building reusable components, wiring pages to the router, and tightening up state management. While the UI comes first, we will also expose fresh endpoints as we go; you’ll help shape the Node.js / API that feeds those screens. We already have a rough domain model running in Java micro-services, so expect to consume and occasionally extend those services rather than start from scratch. Clean, well-tested code, Git-based collaboration and clear commit messages are essential because we’ll be working side-by-side and merging often. Deliverables (acc...

The project is already up and running on my local stack (Linux / macOS, nginx as the web server, MariaDB for data, everything container-friendly). If your on windows u will need wsl to run it like I do. please dont bid if u cant set these up. Functionally it does what it should, but the overall layout is amaateur. You’ll work directly in the existing codebase, tweak or rewrite the HTML templates, CSS (or a pre-processor if you prefer), and any lightweight JS that controls visual behaviour. No back-end changes are needed; routing, queries, and business logic stay as-is. Deliverables • New page structures, there are 5 independant html pages and 2 vue (main user web and admin page) that improves hierarchy and readability. • Updated style sheets reflecting a clean, mode...
I have a desktop solution that mixes C# (WPF, a few ASP-NET-style service layers) and VB.NET (classic Windows Forms). Both stacks matter equally, so code will sometimes jump between the two. Current priorities are: • Robust user-authentication built directly into the client • Smooth, responsive data-visualisation screens (charts/grids) • Reliable file-handling routines for import, export and local storage The existing repository is in Git; each module compiles under the latest stable .NET. I’ll grant access branch-by-branch so we can review pull requests together before merging. Deliverable is a working desktop build with clear, well-commented source that shows the three features above fully integrated and tested on Windows 10/11. If a lightweight service o...

I built AVA – A Vital Archive – to give families and organisations a simple, secure place to preserve stories, photos and documents. After investing about $40 k in development I now need help tightening the product and getting it in front of the people who care most about history and legacy. Code & Current State • Source lives in my private GitHub repo (React-Native front end with a Node/Express back end). • AI summarisation and tagging is already wired in but is not functioning correctly. • Users sometimes hit slow load times and the occasional crash when browsing large collections. What I need next month 1. Bug fixes and performance improvements that keep the app smooth even with thousands of images or large video files. 2. Reactivate and har...
I manage a hiring funnel for several US-based software companies and I want to delegate the technical interview stage to an experienced professional. The role is strictly about technical interviews in the software-development domain: live coding, architecture discussion, and problem-solving conversations that mirror what candidates will face inside these companies. Because many of our applicants are already comfortable with American business English, I need you to model the same level of fluency—C1 or higher—while bringing the fresh perspective of a non-US speaker. Your background must include hands-on software development so you can probe areas such as algorithms, design patterns, version-control workflows, and contemporary tooling (think Git, Docker, cloud services, etc.). F...
My React-based appointment platform is almost ready to ship, but two stubborn issues in the scheduling logic are blocking release: • The time-slot generator sometimes shows options that should be unavailable. • When a user hits “Book,” the request hangs far longer than it should. I need a developer who can dive straight into the existing React frontend (hooks and context), trace the slot-generation flow through to the scheduling API, and deliver a clean, well-tested patch. You’ll verify that only legitimate slots appear under every timezone/working-hours scenario and profile the booking call so the confirmation returns promptly. Deliverables (acceptance criteria) 1. Updated logic that always publishes correct, conflict-free time slots. 2. Booking operat...
I need a clean, one-click PDF download added to our existing software application. When any visitor hits the new “Download” button, the latest PDF should be served immediately—no login prompts or extra hoops. You’ll receive the current repo and a quick tour of its structure. Your job is to slot the feature in without disturbing what’s already there, following our naming conventions and UI style. Deliverables: • Fully functional download button wired to the PDF generator or static file, as appropriate to the codebase • Well-commented code committed via Git with clear commit messages • A short README outlining installation steps, changed files, and any environment variables Acceptance: I can pull the branch, build, deploy, click the button,...
I recently bought a Laravel-based applications and now need an experienced developer to take it from “off-the-shelf” to perfectly tailored. The work splits into two clear streams: • Design/UI improvements – Tweak page layouts so the screens flow better across desktop and mobile. – Introduce a handful of fresh components (think dashboards, modals, or cards) that follow the existing design language. – Modernise several dated sections, replacing stock elements with cleaner Blade/Tailwind versions. • Feature enhancements – Build a few brand-new capabilities we’ve scoped i. – Refine some current features to run faster and feel more intuitive. – Hook the app up to two external APIs. Deliverables: updated so...
I recently purchased a commercial Laravel starter kit and have run into two main pain-points: certain features break during specific user actions and overall performance drags under load. I need an experienced Laravel developer to dive into the repository, trace the root causes, and ship clean, tested fixes. Here’s what I’m dealing with right now: • Functionality issues surface only when particular workflows are triggered (for example, navigating deeper into authenticated areas, saving complex forms, or hitting AJAX endpoints). Your task is to audit the codebase, locate and repair the offending logic, then optimise any queries or middleware that are slowing things down. I’m already set up with Git, so you’ll work in a separate branch, commit frequently, a...

Here’s where I need your help: • Data preprocessing & cleaning – imputation, SNP quality filters, population structure checks. • Model development & tuning – implement or refine the models above, explore hyper-parameter grids and suggest new algorithms when they make sense. • Performance evaluation & analysis – rigorous cross-validation, predictive-ability metric...
My Node.js / Express site on Hostinger is throwing a 500 error whenever the frontend calls POST /hcgi/api/sessions/generate-session. The most pressing issue is integrating the OpenAI API so the endpoint can actually build text-based learning content on demand. Here’s what I need done: • Analyse the current controller for /generate-session, trace the 500 stack trace, and patch whatever is blocking a successful response. • Wire in an OpenAI completion (or chat) request so each call returns coherent, text-only learning material. • Make sure the frontend form already on the page submits correctly, hits the endpoint, and surfaces the AI-generated lesson back to the user. • Push the working code to my Hostinger VPS, run a live test, and leave the environment in ...

I have a series of internal utilities written in Python that need to grow beyond quick-and-dirty prototypes. For two hours most mornings (08:30-10:30 IST, though we can slide a little when needed) I’d like to work side-by-side with someone who can drive the development of fresh, production-ready automation scripts. The immediate goals are: • expanding our file-management helpers so they sort, archive, and version large folder trees automatically; • building data-extraction and processing routines that pull raw CSV, Excel, and JSON files, cleanse them with Pandas, and push the results into a reporting pipeline. Knowledge of yaml files is plus Your role during the session is to sketch clean architectures, pair-program where necessary, and leave me with clear, commented co...
I am starting a modern web application and have already committed to React for the entire front-end experience. The design calls for a clean component architecture, responsive behaviour across desktop and mobile breakpoints, and smooth state management—so expect heavy use of hooks, Context, and, where appropriate, Redux Toolkit. On the server side I’m still weighing options. If you prefer Node.js, Django, or Ruby on Rails, let me know how you would structure the API layer, handle authentication, and manage data persistence; the final decision will be based on whichever stack you can demonstrate will scale cleanly and deploy easily to a cloud host such as AWS or Vercel. Key deliverables • Production-ready React front-end (TypeScript welcome) • REST or GraphQL API...
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 that pre...
I’m ready to upgrade my website with real-time flight and hotel booking and to process every transaction through PayU.

I need a seasoned embedded-systems engineer to help me complete and refine firmware for an industrial solar tracking pilot we are about to install in the field. The hardware platform is an STM32-based control board that already handles basic I/O; what I need next is rock-solid actuator control logic and tight integration with the rest of the system. Key priorities • Linear-actuator position control is the single most critical feature. Accurate sun-tracking algorithms must translate to smooth, repeatable movement, end-stop detection, stall handling, and safety interlocks. • The board talks over a CAN bus to a Linux-based gateway. Your code should package position reports, health data, and fault codes into our existing CAN message set and respond to incoming commands in real t...
