AI Developer Advocate · JetBrains

Hey, I'm Jan-Niklas

I test AI coding workflows against real codebases, then explain what held up, what broke, and why it matters for the developer shipping the result.

What I Test

I work as an AI Developer Advocate at JetBrains. I test coding agents, IDE workflows, and developer-tooling ideas against the standard that matters: would I trust this in a real codebase?

I'm a former RxJS core team member and an Angular Google Developer Expert (GDE). That background keeps me focused on architecture, debugging, and maintainability rather than demo magic.

My take on AI tools is simple: show the workflow, show the failure modes, and make the verdict useful to developers who still own the result.

What You'll Find Here

This site is built for working web developers. I publish tested AI workflows, lessons in engineering craft, grounded takes on industry shifts, conference talks, and podcast conversations about ideas that survive contact with real code.

Outside the Experiments

When I'm not testing workflows or recording conversations, I'm usually chasing better coffee and spending time with my family.

Grab a coffee chat if you want to swap notes on AI tools, frontend engineering, or an interesting idea.
