About Sami Rahman

01 / Signal

I'm Md Samiur Rahman Mian — most people call me Sami Rahman (or Sam Rahman), and online I go by srs404. IT Project Leader and full-stack developer in Oshawa, Ontario.

I work where software, servers and people meet. I write code, run infrastructure, and lead the teams that deliver both — sitting between clients, vendors and executives to turn ambiguous problems into systems that hold.
