André Staltz

User Interface Programmer

Hi, I'm a user interface developer and designer, with extensive knowledge in reactive programming. I am obsessed with the future and I want to make it become reality today.

ABOUT ME

I come from Brazil, but have no interest in football and many other things that identify them. I'm rare. Now I live in Finland, where it's nice and cold.

I work as a Senior Web and Mobile Developer at Futurice. In the past I have been an entrepreneur and full stack developer at my own startup Iroquote, a platform for online discussion forums.

I have done programming in all kinds of fields, but I have discovered that my passion and focus is with highly interactive user interfaces. I want to make great ideas become reality, with obsessive attention to detail.

Currently, I'm enthusiastic about reactive programming, JavaScript, and functional programming. You might have read an introduction to Rx that I wrote. I have built RxMarbles, contributed to ReactiveX.io, and my current mission is to redefine how we structure and understand user interfaces with the JavaScript framework Cycle.js.

I have given talks about those topics at various conferences, check a list of my recent talks below.

EXTRAS

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 started programming by making games. With my friend Glauber Kotaki I've made some games such as Cold Tension, and by myself I've made RGBlend, a color puzzle game.

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.

MY NAME

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.
