I’m building a production-ready, user-facing web application and need a developer who can own the stack end-to-end. The front-end is React.js, the back-end runs on Node.js with Express, and all data is persisted in MySQL. You’ll shape new features with our UI/UX designer and product manager, translate wireframes into responsive components, develop clean server-side logic, and keep performance tight on both tiers. Well-structured, scalable code, thorough code reviews, and automated tests are part of our everyday workflow, so I’m looking for someone who shares that mindset. Along the way you’ll design and optimize the database schema, integrate third-party APIs, and continuously suggest technology or architectural improvements that future-proof the platform. Deli...
An existing web platform built with FastAPI for the API layer, for the interface, and PostgreSQL as its data store is roughly 80 % complete. Core authentication, routing, and database models are in place, yet several pieces still need tightening before a production launch.

Outstanding work may include refining API response handling, extending a handful of endpoints, wiring the remaining React pages, polishing UI states, and cleaning up a few database queries that currently hamper performance. During our kick-off call we will agree on the exact priorities and sprint order, but code quality, test coverage, and deployment readiness are non-negotiable throughout....

I need an experienced full-stack developer (within India) to jump straight into an existing React.js + Node.js platform and push its mapping features to the next level. The immediate focus is on the backend and database layer: extending our Node/Express services, fine-tuning a MySQL schema, and making sure geospatial and financial data flow smoothly through the system. The key challenge is deep Google Maps work. You’ll be parsing and displaying KMZ and KML layers, wiring them to live MySQL queries, and exposing clean API endpoints the current React front-end can consume. Solid GIS know-how is a must; you’ll be working with spatial indexes, projection quirks, and distance calculations every day. Because this is an enhancement, the core codebase is already in place and well-doc...

I need an RFID-based platform dedicated to Asset tracking, but instead of equipment or vehicles the “assets” are People moving through my facilities. The system must reliably capture and store two key data points for every tagged individual: Entry and exit times as well as their wider Activity history while on site. Core workflow RFID badges (or wristbands) will be read at all controlled doors and strategic zones.

I need hands-on, day-to-day help from a seasoned DevOps Engineer to keep our AWS environment running smoothly while we roll out new features. The immediate focus is on three pillars: building a reliable CI/CD pipeline, codifying our infrastructure, and tightening monitoring and logging so issues surface before our users ever notice. We host everything in AWS, so you should feel at home with services such as CodePipeline, CodeBuild, CloudFormation or Terraform, ECS/EKS, CloudWatch, and any complementary tools you prefer (Jenkins, GitLab CI, Prometheus, Grafana, ELK, etc.). While DevOps work is priority one, experience touching data-engineering workflows or handling database administration will be an advantage as those needs crop up after the core automation is stable.

I need a clean, scalable foundation for a new SaaS product built strictly with Node.js on the backend, React.js on the frontend, and MongoDB for persistence. I already have the idea—what I’m missing is a well-structured codebase that lets me plug in features quickly without fighting architecture later.
Hi I will share the details with the shortlisted candidates. Thanks
My MERN stack application is ready for production and I need it running smoothly on an AlmaLinux server. You’ll start with a clean box that currently has only SSH access; no Node.js, MongoDB, or build tools are installed yet. I do want help setting up that entire environment, so plan on installing the required versions of Node, npm/yarn, MongoDB and any supporting packages. Apache is the preferred web server. Please configure it as a reverse proxy so the React front-end and Express API are both reachable under the same domain, served over HTTPS with a free Let’s Encrypt certificate. If you like using PM2 or a similar process manager to keep the Node processes alive, that’s fine—just document what you do. Deliverables: • Deployed, publicly accessible MERN ap...
I am building a cloud-hosted platform dedicated to competitive examinations and need the entire stack delivered—from database schema to responsive UI. The core feature is an AI-powered written-answer evaluator: large language models must read a candidate’s response, compare it to a rubric that I will supply, assign a score, and store both the marks and the model’s reasoning for audit. Beyond scoring, the system should include: • Role-based user management (students, admins, moderators) • Personal dashboards that surface recent tests, performance trends, and detailed answer feedback • A secure admin panel for uploading new exams, editing rubrics, and downloading results in CSV/Excel • Site-wide analytics tracking log-ins, test attempts, and e...

I’m ready to move from idea to working product and need the full MERN stack foundation put in place. The core requirements are straightforward: • Secure user authentication – account creation, login/logout, encrypted passwords, token-based session handling, and role support so I can expand permissions later. • Real-time data updates – live push of new content or status changes without page refresh, ideally powered by or a similarly lightweight WebSocket solution. Everything should be built with React on the front end, Express and Node.js for the API layer, and MongoDB to persist data. Clean, well-commented code pushed to a Git repository and instructions for local setup and cloud deployment are part of the hand-off. A minimal responsive UI is fine; the pr...
Job Title: Full-Stack Developer to Migrate Project from Firebase to Vercel/Render Job Description: I am looking for an experienced Full-Stack Developer to help me finalize and deploy my web application, Jambo-Rafiki. After persistent issues with Firebase, I have decided to move away from the Firebase ecosystem entirely and migrate the project to a more streamlined hosting environment (preferably Vercel for the frontend and Render/Railway for the backend). The code is currently hosted in a private GitHub repository and is organized into a client (Vite/React) and server (Node.js) structure. Scope of Work: Code Review: Quickly assess the current client and server folders to ensure they are ready for deployment. Migration: Move the project away from Firebase Hosting. Deploymen...
My application currently uses Firebase for data storage, but I’m ready to phase it out and move all new users to a dedicated MongoDB database. The immediate goal is to stand up a production-ready MongoDB instance, design an equivalent schema, and route new sign-ups there while existing users continue operating without disruption. Two data sets need to be copied across right away—user profiles and user activity logs. I already have full read/write access to the Firebase project, so exporting the raw JSON or collections won’t be an issue; what I need is a clean import into MongoDB with indexes, validation rules, and any minor field remapping that improves query performance. All other Firebase collections can stay untouched for now. Once the MongoDB side is stable, the...
I’m building a web application and need a developer who can own the entire stack. The interface will be written in React, the server logic in Node.js, and data stored in MySQL. Your responsibilities span setting up the project structure, implementing features, optimising performance, and providing ongoing maintenance. You should feel at home designing component-based UIs, crafting secure REST or GraphQL endpoints, modelling relational schemas, and deploying to a cloud host such as AWS or DigitalOcean. Familiarity with TypeScript, Express, Sequelize or TypeORM, Webpack/Vite, Jest, and Docker is a plus; if you have a different workflow that still centres on React + Node.js + MySQL, I’m open to it. We’ll start with an MVP and iterate. When you reply, please include links t...

I’m ready to launch a technology-focused B2B marketplace that brings buyers and sellers together in a streamlined, Alibaba-like environment. The core of the project is a full web platform where companies can register, showcase products, and negotiate deals directly on site. Scope of work • User onboarding must feel effortless, so I want social-media logins (LinkedIn, Google, Facebook) baked in from day one. • Sellers need an intuitive dashboard to create and manage detailed product listings—images, specs, bulk-pricing tiers, and inventory status. • Buyers should be able to browse or search listings, save favorites, and start secure, real-time conversations with sellers through an internal messaging system. I’m open to adapting a solid pre-built sc...

Kode harus bersih, terdokumentasi, dan mudah diperluas agar ke depan saya bisa menambah media management maupun pembuatan halaman dinamis tanpa refactor besar. Teknologi pilihan tetap fleksibel; stack umum seperti Laravel, Node.js + Express, atau Django dipersilakan selama arsitektur mendukung RESTful API dan keamanan standar industri (hashing kata sandi, proteksi CSRF, validasi input). Integrasi dengan database relasional (MySQL atau PostgreSQL) diperlukan, dan saya mengutamakan penggunaan migration serta seeding untuk kemudahan deployment. Deliverable: • ...
