Project details

You will get expert bug fixes, feature updates, and code improvements for your existing React, Next.js, or Node.js web application.

Inherited a broken codebase? Lost your developer? Something failing in production? I take over existing full stack projects, find the root cause, fix it properly, and document every change so your next developer is not stuck.

What I handle: React and Next.js frontend bugs, Node.js, Express and NestJS backend issues, REST API and GraphQL integration problems, MongoDB, PostgreSQL and Supabase database errors, authentication and JWT issues, performance optimization, and new feature development inside your existing web app.

9+ years of production experience with React, Node.js, TypeScript and the MERN stack. My recent clients hired me for exactly this work: bug fixing, code review, feature enhancements, and API integration on live projects.

You get clean documented code, a clear explanation of what was broken and why it happened, and full source code access after delivery.

Send me your repo link or a description of the bug before you buy so I can confirm scope and timeline.

WHAT I BUILD

- SaaS Platforms and Admin Dashboards
Multi-tenant SaaS applications with role-based access control, document handling, activity logs and analytics. Built with React or Next.js on the frontend and Node.js, Express or NestJS on the backend, with MongoDB or PostgreSQL underneath.

- React Native Mobile Apps for iOS and Android
Cross-platform mobile app development using React Native (CLI and Expo). Push notifications, real-time features, offline support, and full App Store and Play Store deployment. One codebase, native-like performance, and the same developer owns the backend API it talks to.

- MERN Stack Web Applications
Complete MERN stack development: MongoDB, Express.js, React and Node.js. Also Next.js for server-rendered and SEO-critical web apps. Responsive UI with Tailwind CSS, TypeScript throughout.

- REST APIs, GraphQL and Integrations
Secure REST and GraphQL APIs with Node.js, Express and NestJS. JWT and OAuth authentication, RBAC, WebSockets for real-time systems, Stripe and third-party API integration, microservices for data-heavy workflows.

- MVPs for Startups
Idea to deployed product in weeks. Web app, mobile app, or both. Clean architecture from day one so your MVP does not need a rewrite once users arrive.

- Bug Fixes, Refactors and Code Review
Inherited a broken codebase or lost your developer? I take over existing React, Node.js, Next.js and React Native projects, fix what is failing, and document every change.

TECH STACK
- Frontend: React, Next.js, TypeScript, JavaScript, Tailwind CSS, Redux, responsive UI
- Mobile: React Native (CLI and Expo), iOS, Android, push notifications, App Store and Play Store deployment
- Backend: Node.js, Express.js, NestJS, REST APIs, GraphQL, WebSockets, JWT, OAuth, microservices
- Database: MongoDB, PostgreSQL, Supabase, Firebase, schema design, query optimization
- Cloud and DevOps: AWS, Vercel, Firebase, Docker, CI/CD pipelines
- Tools: Git, GitHub, Postman, Jira, Agile

WHY CLIENTS HIRE ME

Web and mobile in one hire. Most full stack developers stop at the browser. I ship the Next.js dashboard and the React Native app that connects to it, sharing the same API and the same data model.

Production experience, not tutorial experience. Nine years across two established software companies before freelancing, on real products with real users.

Code your next developer can read. Typed, structured, documented. No handover mess.

Timezone flexible. I overlap with US, EU and Asia schedules and reply within 0-4 hours.

HOW WE START
Send me a message or an invite with a short description of what you are building, your timeline, and whether you need web, mobile, or both. I will reply within a few hours with an honest answer on fit and how I would approach it. If it is not my strength, I will tell you.
