about_me.py

Who compiles this code.

I'm a full-stack developer, mobile application engineer, and AI/LLM integration engineer at Daffodil International University. I have hands-on experience building production-grade web, mobile, AI-powered, and enterprise software solutions.

I specialize in building end-to-end products using Python, Dart, React, React Native Expo, Flutter, FastAPI, Supabase, and Firebase. I have led engineering teams and architected platforms serving thousands of active users.

My current research focuses on Medical AI, Computer Vision, and Bangla Handwritten Character Recognition, developing uncertainty-aware hybrid ensembles for brain tumor classification and character recognition.
