I'm a full-stack developer based in Dhaka, building production web and mobile apps with React, Next.js, TypeScript, and React Native. Day to day I work across the stack, from clean interfaces in Tailwind and ShadCN UI to solid backends in Node.js, Express, Django, and MongoDB.
I've helped build a SaaS product from the ground up, so I care about architecture and maintainability as much as shipping fast. I write code that the next developer, often me months later, can actually read.
If you want someone who asks the right questions before touching a line of code, let's talk.

FAQ
What do you need from me to get started?
To start immediately, I need: 1. Access to your codebase (via GitHub/GitLab repo or a zipped file). 2. Steps to reproduce the bug and relevant error logs or screenshots. 3. Details about your runtime environment (e.g., Node version).
Can you fix issues in my live/production environment?
For safety, I recommend working on a local, staging, or separate git branch first. Once the fix is thoroughly tested and verified, you can deploy it safely to production without risking downtime.
What if my bug requires backend or database troubleshooting?
I cover both frontend and backend debugging. I can trace issues through Node.js/Express controllers, API route parameters, and database queries (ORM layer like Prisma or Mongoose) to find the root cause.
Will my codebase remain confidential and secure?
Absolutely. Your code, API keys, and project details are kept 100% confidential and will never be shared, reused, or stored after the order is completed.
