A decade of
shipping things
that had to work.

I'm Raju — a platform architect and full-stack lead based in Dhaka. I've spent the last ten years shipping production SaaS systems, most recently in voice AI and intelligent automation. I like tidy abstractions, honest documentation, and small teams that trust each other.
