Łukasz Jagiełło
Engineering leader
San Francisco Bay Area
Hi, I'm Łukasz. I got started in 2003 running the dorm network at Gdańsk University of Technology, and I've been building infrastructure, and the teams behind it, ever since: at Fandom, at Fleetsmith and then Apple, and as a co-founder of Tempest. These days I lead teams building AI agents and developer platforms. The full résumé lives on LinkedIn.
Outside work I play CTFs as LCF. My best finishes so far are 4th of 808 at MetaCTF's March Flash CTF and 11th of 890 at KnightCTF. Lately I've been teaching coding agents to play too: with ctf-skills, one solved 50 of 54 challenges at BSidesSF. I also like taking apart the things around me, from firmware and wire protocols to the gadgets on my desk.
I'm part of the Burning Man community. I help build art with Titanic's End, the crew behind the Iceberg art car, and I'm making IceFinder, a wearable LED pendant, for the 2027 burn.
I also collect records, mostly breakbeat hardcore and jungle on 12-inch vinyl, with a serious Kniteforce habit. The collection is close to 2,000 releases, all of it on Discogs.
