Hi,

I am Raphaël Lemaitre, and it appears you landed on my website.

According to my Bluesky bio, I am

Scala lover, FP enthusiast, Speaker. Creator of Pillars, making complexity simple. Former CTO back to what I love: coding. ADHD adventurer with endless project ideas. I learn, I optimize, I build.

This sums up well who am I, but I’ll detail a bit more.

I’m a programmer (mainly using JVM languages but not only) living in the Paris area, France. I started working in 2000 and have worked mainly for software vendors. You can look at my LinkedIn profile for more details.

Writing this page, I find that my Bluesky bio misses something: I love learning. This is one of the main reasons I made this website (with its blog) : I found writing and sharing are the best way to learn. To quote Andrew Hunt in The Pragmatic Programmer: From Journeyman to Master:

An investment in knowledge always pays the best interest.
