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.

As a hobby, I'm the author of bootOS, an x86 operating system in 512 bytes, and its companion bootBASIC interpreter in 512 bytes; I've developed the world's smallest chess programs in C, Java, Javascript and x86/6502 machine code. 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.

I'm the author of the books Toledo Nanochess: The commented source code, Programming Games for Intellivision, Advanced Game Programming for Intellivision, ColecoVision Games Guide, Programming Boot Sector Games, More Boot Sector Games, and Programming Games for Atari 2600. My games Princess Quest and Mecha-8 are included inside the Colecovision Flashback, Space Raid is on the Atari Flashback 9 Gold, and Princess Quest is on the Evercade Intellivision Collection 1 cartridge.

I've been interviewed by newspapers, magazines, radio, TV and podcasts.

I give talks about programming topics and the influence of software in the society, and I'm a game programming and design consultant. I have been a lecturer in Mexico at the ITESM, ESIME, UNAM, and Justo Sierra University.
