About
I'm a full-stack developer and founder based in Luxembourg, currently building Rerun, a platform designed to make it easy to build 24/7 AI agents for any task. As CEO of Rerun, I focus on making autonomous agent creation accessible, allowing users to automate recurring work without needing deep technical expertise.
Beyond Rerun, I've founded Mailhub, a transactional email API offering customizable templates, internationalization, and reputation management for outbound email infrastructure. My freelance work spans full-stack development for companies like Hotelspeaker, bevopr, and ANTIDOTS Group, where I've built and maintained web platforms using technologies such as ReactJS, VueJS, .NET, Firebase, AWS, and MongoDB.
With a background in information systems management from Henallux and additional training in UX design from Université libre de Bruxelles, I combine technical development skills with a product and user-experience mindset. My experience ranges from building marketplace platforms and internal tools to architecting APIs and deploying cloud infrastructure, and I now channel this expertise into building AI agent tooling with Rerun.
