Hi. I'm Sajad.

I'm the backend person on AI products. The model gets the applause; I take care of what it stands on.

How I work

Most days it's Python: FastAPI, PostgreSQL, Redis, and the plumbing that moves work between them. I own the architecture I write and the operations after it. When something breaks, the first thing I look for is the missing test.

I like boring insides and clear outsides. A repo should tell you what it does, then get out of the way. If it needs a sales pitch, it's not finished.

On the side

Security, one topic at a time, attacks and defenses both. What I learn tends to leave as a tool, not a note. vpnbox, a free Linux VPN in a single stdlib-only Python file, started exactly that way.

Right now

The vpnbox beta is out (v1.0.0-beta4), and Lexora is next in line for hardening. Also on GitHub: HookFlow (webhooks that never get lost) and neuDB (a tiny crash-atomic database).

Longer notes live on the Writings page, and Contact has every way to reach me.
