    William Souza

    Java Expert (top 1% Advanced Java)!

    United States - Last active: 1 day ago - Tests: 6 - Portfolio: 1

    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 you have a bug and you don't have proper documentation, don't worry, I will fix it!

    Frederic Bonnet

    France - Last active: less than one minute ago

    Better call Fred. I code therefore I am. I wrote my first program when I was 12. It was on a 16-kB Sinclair ZX-81 plugged on the living room TV. Ah, memories. Professional R&D engineer since I'm 23. Now I am 41. After all these years I think I can program just about anything, from back office to end user GUIs. I especially like algorithmic stuff (I have a research background in CS and computational geometry) and system-level C. But while implementation is only the final stage, design is the most important part in a project. I've been a senior software architect for some years now, so I can help you besides mere coding tasks (e.g. refactoring existing codebases). I also enjoy data mining and analysis. I'm fluent in English but my native language is French, so if you also have translation jobs that involve technical knowledge then I can help as well. I routinely write technical documentation for my daytime job in the telco industry (specifications, design, operation manuals, etc).
