Engineering, testing and shipping reliable, type-safe interfaces
Hi, I'm Martin, a senior frontend engineer working in Vue, Nuxt and TypeScript. AI can now write UI faster than teams can review it, so I build the tests and checks that make it safe to ship.
How I ship
AI agents write and review the code. I build what lets them prove it works.
- 500+PRs a month
- Written and reviewed by AI agents
- 99%of PRs kept
- Never rolled back or fixed later for a bug they introduced
- 10+gates on every PR
- Specs, linting, type checks, unit, end-to-end and visual regression tests, and CI rules enforced by GitHub rulesets
- 0humans in the test loop
- The goal: people write the specs and set the rules, and the harness tests every change
My rule: “leave the codebase better than you found it.”
Projects & Open Source
Tools I build in the open, and how I give back to the ones I use every day.
Work Logs
The timeline starts when I went full time. I've been writing code since high school in 2010, through a BSc and a few small jobs.
