Hi, I'm Reza.
25 years building software and leading teams across healthtech, AI, and developer tooling — currently CTO at a Berlin AI MedTech company. My open source has 22K+ GitHub stars, and I write about agentic development for 7,000+ engineers.
Now I take on a handful of teams at a time. Got a hard problem? I like those.

What do you actually do?
I advise teams on agentic AI and engineering strategy, help teams set up AI implementation sprints that actually pay off, coach engineering leaders 1:1, and speak on AI-assisted development. One operator, deep involvement — never a deck-and-disappear.
How does it start?
A 20-minute call. You describe the problem; I tell you honestly whether and how I can help, then send a one-page plan. No drawn-out sales cycle.
Where are you based?
Berlin, Germany. I work with engineering teams and founders remotely worldwide, across time zones.
