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.

PromptKit 1.0 is out: prompts as files, a linter that finds the typo before your invoice does, and eval suites that run in CI with no API key and no bill.
The Value Of A Closed Feature Request
My library has a page listing what it will never do. It's the most useful page in the docs, and it's the reason people can adopt it.
Rendering A Prompt You Did Not Write
The moment prompts become files, they arrive from places you don't control. A template engine with defaults on is a code-execution primitive.
