Hey there 👋

I'm Guillaume, a Solutions Engineer at GitHub, self-appointed First Warden of AI Context and Defender of Developer Velocity. I live near Paris 🇫🇷 but I've called the US 🇺🇸 and China 🇨🇳 home at various points in my life.

After 16+ years in the data world, wrangling SQL, building warehouses, and demoing software to Fortune 500 companies, I now get to help developers ship better code, faster. Before GitHub I worked at OneTrust and SAI Global in the GRC and privacy space, picking up certifications like CIPP/E, SAP, and Oracle along the way.

Outside of work I'm usually tinkering with my homelab, automating things around the house that probably didn't need automating, exploring a new country, or watching way too many movies. I also dabble in Go, HTMX, and anything Linux-related.

My main side project is Pecunia, a free portfolio tracker for French investors to manage PEA and CTO accounts across brokers and simplify tax reporting. I'm also working on Demofl.io, a Chrome extension that makes building and presenting demos a lot less painful for fellow Solutions Engineers.

Find me on LinkedIn and GitHub. Always happy to chat.
