Know about me

Full-Stack Developer and a little bit of

I'm Ali Hasan Muzahid, an undergraduate student pursuing a Bachelor of Urban & Regional Planning (BURP) at RUET (Rajshahi University of Engineering & Technology, enrolled 2023) and a dedicated Full-Stack Software Developer. I merge analytical spatial planning methodologies with modern, robust web systems.

I embarked on my web engineering path with Programming Hero in June 2025, completed all programs (SCIC, SCPC, and EndGame 12) in April 2026, and led team NextGen Coders to win the EndGame 12 TOP TEAM Award with CodeArena.

In addition to full-stack engineering, I utilize ArcGIS Pro, SPSS, Python, and Jamovi for academic spatial research and socioeconomic modeling. Actively open to global remote software engineering roles!
