I'm a Programmer and a Tech Lead. A Trainer, Community Manager and a Blogger, too. I'm an Open-Source and TDD advocate. I design, build and lead hight-quality software projects.
I'm passionate about what I do and I'm blessed to do what I love.

I started using computers when I was 9, programming when I was 10. Those days, I wrote many programs in Basic for Commodore, mostly small games.
When I was 18, I got my degree in Computer Technical. Back then, I wrote some real-life programs in Visual Basic, like an administrative software for taxi agencies.

My first paid work was in a banking software company called G&F in February of 2000. I started working as a junior programmer and through the years I became senior developer, tester, project leader, tech leader and finally, software architect. Those systems had strong volume, performance and security requirements.

After eight years on G&F, I felt the need to grow up and embrace new technologies. Then I switched to Novamens, where I started developing Erlang systems for a VoIP company.

At the same time I was studying in the Buenos Aires University to became the computer scientist I am now. My final thesis project was a development platform built in Haskell, called λPage.

I spent two years working at Novamens, then I met Chad DePue when he was creating Inaka. I joined the company and I worked there since its very beginnings, developing highly concurrent applications. I eventually became its CTO and when Inaka was acquired by Erlang Solutions, I worked there as a Tech Lead and Trainer, too.

I'm now a software engineer again and, after several years working with Erlang, I feel very confident with it. I've been in a Tech Lead position for enough time to feel confident with it, too. Nevertheless, I keep learning new stuff about both worlds every day. And what I learn, I share through my blog :)

During my days at Inaka, Erlang Solutions and now BairesDev, I've created strong bounds with the development community, both locally and worldwide. That positioned me as the local community manager and allows me to speak publicly in various conferences around the world.

What I like most of my work are the challenges and the possibilities to use my creativity in a productive way.


I prefer jobs where I can learn, build or discover new things.  I like jobs that let me be creative.  In fact, I enjoy challenging jobs where I must be creative.
