    I'm a tech enthusiast with 20 years of experiences with various fields of IT. For the last 5 years i build a blog for supporting the wonderful Raspberry Pi microcomputers: Knight of Pi (www.knight-of-pi.org), gave Raspberry Pi/ IoT workshops and developed some prototypes. Before that, i worked with Python and web technologies (Django, WordPress and other CMS) . I also have a Diploma in Bioinformatics, but didn't work in that area after leaving university. I've recently moved to Brasil for facilitating microcomputer education here and i'm looking for some interesting and challenging Python/Raspberry Pi projects on the side. There's a collection of my code examples for Raspberry Pi beginners on GitHub (https://github.com/JoBergs), but please keep in mind that it's mostly sample and not production code. less
