About Me

Hi, I'm Afnan Mahmud

I'm a Senior Full-Stack Engineer with 5+ years of experience — founder of the agency Cholo Bohudur, and an international freelancer building production web & mobile products.

I believe the best way to learn programming is by building real projects — not watching endless theory videos. So I teach the exact stack I ship with every day, hands-on and in Bangla for maximum clarity.
