Hello, I’m Ludo.

Software engineer by day. The rest of the time, I build tools anyone can use for free.

The day job

I’m a software engineer at hemea, a renovation marketplace. What I like best is talking to the people who use what we build, then shipping what they need.

I didn’t study computer science. I taught myself, and had my first developer job six months later.

Before code, Loveman

In Dublin I rode a heart-covered pedicab in a heart suit, giving out free hugs and crêpes. It even made the paper. The free tools are the same idea, in software.
