Hey there 👋

I'm Guillaume, a Solutions Engineer at GitHub where I help developers ship better code, faster. I live near Paris 🇫🇷, but I've called the US 🇺🇸 and China 🇨🇳 home at various points in my life.

What I do

My day job is all about developer experience. I work with teams to get the most out of GitHub's platform, from CI/CD pipelines to AI-assisted coding with Copilot. I also speak at conferences and webinars on topics like documentation-as-code, AI context strategies, and developer productivity.

Before GitHub, I spent 16+ years in the data world: wrangling SQL, building warehouses, and demoing software to Fortune 500 companies. 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.

Side projects

I like building things that scratch my own itch:

• Copilot Panorama — an interactive visual guide to everything GitHub Copilot can do.
• Pecunia — a free portfolio tracker for French investors to manage PEA and CTO accounts across brokers and simplify tax reporting.

Off the clock

When I'm not working, you'll probably find me 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 like coding in Go, playing with HTMX, and anything Linux-related.

Get in touch

Find me on LinkedIn and GitHub, or drop me an email. Always happy to chat about tech, developer tools, or whatever you're building.
