You will get bugs fixing in your Next.js, React, Node.js, Express, or TypeScript app
Project details
Fast, reliable bug fixing with clear communication and clean, safe changes.
Bugs waste time, break user trust, and block releases. I help teams and founders fix issues quickly—without introducing new problems.
I will diagnose and fix bugs in Next.js, React.js, Node.js, Express.js, TypeScript, and JavaScript projects. This includes runtime errors, build failures, API issues, UI bugs, broken forms, authentication problems, performance bottlenecks, deployment errors, and integration bugs.
My approach is simple and professional: reproduce the issue, identify the root cause, implement a safe fix, and verify it with testing. You’ll receive clean changes (no messy hacks), clear explanation of what happened, and recommendations to prevent the bug from returning.
If you need a reliable engineer who can jump into your codebase and ship fixes fast—send me the issue and I’ll handle it.

About Faridul
Senior Full Stack Engineer | SaaS & Scalable Web and Mobile Apps

They fail because of poor execution. """
Most SaaS projects don't break because of bad code. They break because nobody asked the boring questions before building — how does multi-tenant data stay isolated, what happens when a Stripe webhook retries, who actually owns this socket connection on reconnect.
That's the work I do. I take vague product ideas and turn them into systems that hold up after launch: multi-tenant AI agent platforms, geo-based marketplaces with full Stripe lifecycles and real-time chat, security workforce platforms with geofencing and audit trails. End-to-end, from the data model to the deployed cron job.
The stack: Node.js and Express, Next.js App Router with TypeScript, React Native Expo, FastAPI when Python is the right call. PostgreSQL, MongoDB, Redis, Supabase. I pick what fits the product, not what looks good on a resume.
The part most clients quietly worry about — getting ghosted, getting handed something broken, getting an MVP that can't be extended — is the part I take seriously. Clear PRs, documented tradeoffs, pre-launch hardening checklists, and an honest answer when the right move is to cut scope instead of adding more.
If you're building something that needs to work on day 90, not just day one, I'd like to hear what you're working on. Send the details and I'll tell you what I'd actually do.
I don’t just build features. I build systems.
