About

Building practical software — from web apps to AI and blockchain

Computer Science graduate from BRAC University (CGPA 3.87) with strong problem-solving skills and hands-on experience building practical software. I'm proficient in Python, JavaScript, and SQL — comfortable across the full stack, from SvelteKit frontends to Express.js APIs and PostgreSQL databases.

I also work in blockchain and AI — building smart contracts on Polygon zkEVM, training LSTM models, and conducting research-grade security work published toward the NDSS Symposium. I thrive in collaborative teams and write clean, maintainable code.
