I'm Tamim. I build the parts of a product that users never see, but always depend on.
I'm a backend and DevOps engineer at Advensis, based in Bangladesh. Most of my days go into identity, service routing, retrieval pipelines and the Kubernetes clusters they run on.
What I do
At Advensis I work across three products: NORA Apps for business automation, Vantage for AI-assisted incident detection, and Intellix, an AI course creator. My part is the shared foundation under them — how users sign in, how services find and call each other, how data gets in for retrieval, and how all of it runs on Kubernetes and OpenShift.
I also work hands-on with GPU infrastructure and ML tooling, and I get pulled into real customer environments when directory sync or SSO breaks.
How I work
Pick the boring option first
If Postgres and a clear hook engine solve it, I don't add Kafka. Fewer moving parts means fewer 3 a.m. pages.
Let services describe themselves
Tools register themselves with the gateway, and every service ships its own permissions manifest. No central list for someone to forget to update.
Don't lock the product in
Vector stores are pluggable. Customers keep their own directory as the source of truth. Today's choice shouldn't block tomorrow's.
Say what I actually did
On this site and in reviews: my part, the real trade-offs, and what I'd change.
