Hi there! I'm Yann.

Fascinated by all things computers since before learning to read, turned freelance T-shaped tech engineer (but the T has a few bars, more like a viaduct).

Main bars I wrangle: clouds (mostly AWS and Cloudflare), networks, software engineering. Sounds like something you're working on? Let's chat!
