Story

How I got here

I come from a madrasa background. In 2021 I started freelancing as a Flutter developer.

Between 2021 and 2024 I built and published apps for clients on Google Play.

In 2025 I moved to full-stack work with NestJS, PostgreSQL and Next.js. Now a client gets the app, the server and the admin panel from one person. My biggest project, the ADVANCE IT Platform, has 29+ modules, and I built all of it myself over two years.

Today I run the tech side of Avence Labs as Co-Founder and CTO, and I still take on app projects for founders in Bangladesh and abroad.
