AI & Systems Engineer

I'm Sayef, and I build
systems that work.

Systems engineer turned AI explorer. I come from a Linux, networking, and embedded background and now work at the intersection of customer-facing tech and development support. Outside of work, I spend my time building AI side projects and learning how intelligent systems actually ship. I like making things that are simple, reliable, and useful.
