Hello, I'm

Tabshir Khandaker.

I build software that is meticulous.

A developer who ships products people love.

I'm a Computer Science student at the University at Buffalo, passionate about full-stack development, mobile engineering, AI, and game development. I thrive in fast-paced environments and excel at planning and shipping projects quickly and proficiently.

As the founder of FiqhAI and Let Him Cook, I've built products serving thousands of daily active users. My Roblox games have attracted over 4.5 million players, generated $35,000+ in revenue, and I handle 5,000+ API calls daily. I've written over 150,000+ lines of production code across all my projects.
