I am aSoftware Engineer andProduct Designer. I spend my time building things.

What I am working on:

• I am currently CTO atCrisp, building the future of customer support withBaptiste Jamin.
• On the side, I am also working onProse, a decentralized team messaging app, powered byXMPP.
• I have apersonal website, on which I sometimesblog, publish myprojects and listbooks I have read.
• I maintain popular OSS projects:Sonic (search index),Vigil (status page),Sales Tax (VAT calculator), andmore.
• Oh, and one last thing: I co-inventedMakAir, the world's first open-source medical ventilator.

What I am interested in:

• My domains of expertise are: messaging, protocols, cryptography, the XMPP standard, Rust programming, JavaScript full-stack development, application design, distributed systems, microservices and fault-tolerant architectures.
• On my spare time, I also like to learn about: economics, 3D printing and CAD modeling.
