William Souza

Java Expert (top 1% Advanced Java)!


Lancaster, United States


I love challenges and low-level programming that involves the creation of API's, system's core, math, advanced algorithms, code optimization, artificial intelligence, bits & bytes, debugging other people's code (even without documentation) and everything that involves lots of thinking. I am a hardcore programmer and I code for fun at my free time to keep in touch with new techonologies :) My core experience in the last years is Java (I started with Java since the 1.1 version! pre-swing and with Microsoft Java SDK!), but I've already programmed in a huge variety of languages, like: ASM, PHP, C/C++, C#, VB, SQL, Lua, , etc. I speak "computer", so if ... moreyou have a bug and you don't have proper documentation, don't worry, I will fix it! less
