    France - Last active: 3 days 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).
