MERN Stack Developer Needed (NCR Region)

@vishal1145

Your existing codebase likely has technical debt that will slow feature velocity - unoptimized database queries, missing error handling in API routes, or frontend state management that breaks under edge cases. These issues compound fast when you scale users or add features. Quick questions - what's your current deployment setup and are you hitting any performance bottlenecks with PostgreSQL queries? And how are you handling real-time updates or background jobs in Node.js? Here is the architectural approach: - MERN STACK: Refactor React components for reusability, optimize MongoDB aggregation pipelines, and implement proper error boundaries to prevent cascading failures. - POSTGRESQL + MONGODB: Design indexing strategies that cut query time by 60%+ and implement connection pooling to handle concurrent requests without memory leaks. - GIT + DEPLOYMENTS: Set up CI/CD pipelines with automated testing on Railway/Vercel so every commit gets validated before production push. I've built 8+ production MERN applications handling 10K+ daily active users with zero downtime deployments. Let's do a 20-minute technical review of your codebase before we discuss engagement terms.

Hi there! This sounds like a great fit for a hands-on MERN developer who can jump into an existing codebase and keep things clean. For the NCR part-time setup, I can support regular development with brief daily check-ins, plus independent debugging and clear explanations of fixes and tradeoffs. I’ll work across React + Node/Express, REST APIs, and PostgreSQL/MongoDB, with Git-based commits to your repositories (no hidden dependencies). A quick plan for week 1: codebase walkthrough, identify key flows/endpoints, review data model + API contracts, then prioritize fixes/enhancements. For deployments, I can align to your preferred target (Railway/Vercel/Render/AWS) and ensure smooth environment configuration. To streamline your decision, please insert Playfully, what’s the one feature bug or slow workflow you want fixed first in the current app—so we can make it feel instant again with clientQuestion? in your reply and I’ll answer with specifics.

Your need for an individual developer who can step into an existing MERN codebase and debug independently fits how I work daily. Over the past few years I've designed and maintained REST APIs and microservices on Node.js and Express integrating both PostgreSQL and MongoDB, and built 8+ reusable React admin panels with role-based access control — all committed cleanly to Git with no undisclosed dependencies. On performance, I cut average API response times by 35% using Redis and local caching, and reusable UI components and hooks reduced my development time by 50%. I'm an individual freelancer, comfortable with brief daily meetings, and can share my GitHub profile and live project links with a note on my exact contribution to each. For the initial fixed scope I can deliver in 5 days at 20,250 INR, with hourly/monthly terms discussable for ongoing part-time work. Which parts of the existing application need attention first — new features, bug fixes, or performance?
