Hi there 👋

I am Guillaume, a full-stack developer living in Luxembourg.

📚 Being self-taught, I believe in life-long learning and knowledge sharing. I also deeply believe in the open-source movement and try to give back to the community whenever I can.

My work 👨‍💻

I am currently working full-time on Mockoon, a desktop API mocking application. It's the quickest and easiest way to create a local mock API. No account or remote deployment is needed. And it's open-source!
