About me

I'm a Mexican software developer, I like to write concise and interesting programs. Currently I work for Familia Toledo organization creating neat applications.

Born in 1978, I started programming at age 5 in BASIC, learnt assembly language by age 9 and afterwards the programming languages Pascal, C, C++, Java, Javascript, HTML, CSS and PHP.

I've won five times the International Obfuscated C Code Contest, I came second place in the first JS1K contest and also in the MSXdev'10 contest. So far I'm the only Mexican that has won these contests.
