Full-stack & AI engineer · Dhaka, Bangladesh (GMT+6)
I build web apps and AI features end to end, and fix hard bugs at the root.
49 open-source contributions accepted into Node.js, Jest, React Router, Axios and 15 more
NSU Insights, my own product, used by 4,408 students
I work on bugs that are hard to pin down: stream and timer edge cases, timezone maths, module loading, type-level regressions. I find the root cause, keep the change small, and back it with a regression test wherever the project allows.
