MERN Stack Developer
JavaScript end-to-end, from query to UI.
What I do
The MERN stack is what I reach for when a team wants to move fast without giving up scale: MongoDB, Express, React, Node.js. I've shipped MERN applications running real workloads — admin panels, dashboards, real-time features, payment integrations, complex search.
I worked as a long-running MERN developer at DevStudio (Nov 2023 – 2025) and apply the same stack across freelance engagements. I write production code, set up clean repository structures, and document everything so future engineers (including future-me) can keep shipping.
Comfortable working as a solo developer, embedding into existing teams, or leading a small group of engineers.
How I help teams ship.
MongoDB & Mongoose
Schema modelling, aggregation pipelines, indexing, replica-set ops. Comfortable migrating from prototype-stage flat docs to production-shaped, indexed schemas.
Express & Node.js APIs
REST and JSON-RPC APIs, middleware, async error handling, request validation, rate limiting, session/JWT auth.
React Frontends
React 18, hooks, Context, Redux Toolkit or Zustand, React Query, suspense, optimistic UI. Built with Vite or Next.js depending on requirements.
Real-Time & Background Work
Socket.io for live features, BullMQ / agenda for queued jobs, websocket fan-out, cron schedules.
DevOps & Deployment
Dockerized services, GitHub Actions CI, deployment to Vercel / Render / DigitalOcean / AWS EC2 + RDS, plus monitoring with PM2 or systemd.
Tools I use
Real products. Real impact.
