Bio
Jan-Niklas Wortmann is a Solution Architect at Cursor. Before that he led AI Developer Advocacy at JetBrains, and spent years deep in the Angular and RxJS world as a Google Developer Expert and an RxJS core team member, which is a long way of saying he has shipped a lot of code and broken a fair amount of it along the way.
The Weekly Dev's Brew is where he tests what AI tools actually do for working developers. Not the launch-day demos and not the hype, the messy reality of using these tools on real code. He tries the thing, then tells you what happened, including the parts that did not work.
He is based in Kansas City, drinks more flat whites than he will admit to, and is usually mid-argument with an agent about why it rewrote a file he never asked it to touch.
What The Weekly Dev's Brew is
The Weekly Dev's Brew is a podcast and blog about using AI in real software work. I talk to engineers and tool builders, test workflows myself, and publish what held up and what didn't.
