01.About Me
I'm a Software Engineer based in Rajshahi, Bangladesh with 5+ years of experience building production-grade web applications. I hold a Top Rated badge on Upwork from 4 years of freelance delivery.
My focus is on large-scale frontend architecture, migrations, and scalable UI development across B2B SaaS, healthtech, and AI-powered platforms. I enjoy turning complex problems into elegant, performant interfaces.
I've shipped complex features across the stack — from auth systems and payment integrations to real-time workflows and AI tooling — with a strong emphasis on performance, scalability, and clean state management.
Here are some technologies I've been working with recently:
- TypeScript
- React.js
- Next.js
- React Native
- Redux / Redux Toolkit
- React Query
- Node.js
- Express.js
- Tailwind CSS
- Zod
- Jest
- GraphQL
- WebSocket
- OpenAI APIs
- Stripe
- MongoDB
- PostgreSQL
- Firebase
- Expo
- CI/CD

- ▹Established an OpenAPI-first pipeline auto-generating TypeScript SDK, Zod schemas, and typed hooks from backend spec — eliminating manual API sync overhead.
