Hi, I'm a user interface programmer and reactive programming expert. My passion is to pull ideas from the future and realize them in the present.
I come from Brazil, but never felt like a true Brazilian. Now, I live in Finland, where it's nice and cold. The Finnish culture also matches my personality well.
I currently work as a Senior Web and Mobile Developer at Futurice.
My thing is highly interactive user interfaces. I want to make great ideas become reality, with obsessive attention to detail.

I'm MSc in Computer Science, and for my Master's Thesis I developed HAcid, a Java client library that enables ACID transactions on HBase. In Brazil I graduated BSc in Computational Mathematics at UFMG, where I got to do research on Computational Fluid Dynamics and also Operations Research.
I'm an acoustic guitarist and a composer. I listen to different genres, but mostly instrumental music. Check out my acoustic songs recorded on video. In 2004-2006 I recorded a progressive alternative rock/metal album called O vazio tem um nome. You can find other compositions at Soundcloud.
Staltz is just a nickname I use on the web since 2004. My real name is André Medeiros, but I try to avoid it because it's disappointingly unoriginal.
