Backend & DevOps Engineer · Bangladesh

Mazharul Islam (Tamim)

I build the backend and platform layers that products stand on — identity, service routing, retrieval pipelines, and the Kubernetes underneath them.

Currently at Advensis, working across NORA Apps, Vantage and Intellix.

Recent work

Mostly internal systems, so the code is private. Happy to walk through the design on a call.
