I build web apps and turn prototypes into real products.

From a new website to an app that's outgrown its first version, I help you build, improve, and ship—with maintainable code, automated testing, and reliable deployments.

Software engineer and machine learning researcher, based in Porto.

I started out writing trading algorithms for clients, then did machine learning research at INESC TEC, mostly on time series. For the last few years I've worked on electric fleets, first at Konetik and now at Swytch.
