About Me

🚀

What I Do

I build stable, high-performance Flutter applications — debugging complex production codebases, shipping features under tight deadlines, and developing full apps from architecture to Play Store deployment.

🧠

How I Think

Deep problem analysis before any line of code. I specialize in navigating large, unfamiliar codebases and finding root causes others miss — then fixing them cleanly and efficiently.

🌱

Always Growing

Continuously expanding into advanced Flutter patterns, AI-assisted development, and Agentic AI workflows — committed to staying ahead of the curve in mobile and emerging tech.

Background

Based in Mohakhali, Dhaka, Bangladesh. Fluent in Bengali and conversational English. Open to remote work and international collaboration.
