Olger Chotza
Software Engineer, AI Platforms
I take software that half-works and make it hold, usually a PoC that found real users before it found an architecture, or an app vibe-coded into existence that breaks every time someone touches it. Clean, hexagonal boundaries, mostly: the business logic in the middle, everything else replaceable at the edges. The rest of my time goes to AI platforms, models served in-house, agents wired to tools that do real work. Mostly Python, with Next.js when the thing needs a face.

Stuff I Wrote
See allThe Cache Miss You Pay For Every Turn
A broken prompt cache doesn't fail. It succeeds at 1.25x. What breaks it in an agent loop, what that costs, and a check that finds it with no API key.
The Demo That Parks One Time In Five
I built a car that parks itself by scoring a menu of seven sentences. Then I took away its map, gave it ultrasonic sensors, and watched it get four times worse.
The Normalisation That Picked The Worst Answer
Scoring a fixed menu of options instead of generating text: the maths, the one-pass trick, what it guarantees, and the default that hands 99% to the worst reply.
