About me

Óscar Toledo Gutiérrez
I'm a Mexican software developer, I like to write concise and interesting programs.
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, its companion bootBASIC interpreter in 512 bytes and bootLogo; 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 following books:
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 have been lecturer about programming topics and the influence of software in the society at the UNAM, ITESM, and ESIME. I'm also a game programming and design consultant.
In my free time I'm also a tweetstar with my microstories in @historiasmini.
