Principal Engineer. Advocate. Storyteller.
I'm a Principal Fullstack Engineer working @Amadeus.
I love building elegant frontend systems, scaling dev experience across teams, and exploring the intersection between code, creativity, and teaching.
I stream coding sessions, game dev, and tech experiments on Twitch: @colleim on Twitch
I also run a Tech YouTube channel where I share insights, experiments, and dev tools: @Coleim on YouTube
I build tools, games, and experiments that make dev work more engaging—and sometimes weirdly fun.
Here are some of the small tools and experiments I've built recently.
Bury My Project [React]
Every developer has a “projects” folder that looks like a graveyard. And AI is making it worse. So instead of letting them rot in silence, I decided to give them a proper burial. A public graveyard for dead side projects.
