Raspberry Pi and Python enthusiast

I'm a tech enthusiast with 20 years of experiences with various fields of IT. Since 2012 i own a blog for supporting the wonderful Raspberry Pi microcomputers: Knight of Pi ([login to view URL]), 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. There's a collection of my code examples for Raspberry Pi beginners on GitHub ([login to view URL]), but please keep in mind that it's mostly sample and not production code. My latest IoT/Raspberry Pi projects: * Sensor monitoring station for temperature, humidity, pressure and airflow that allows configuring the sensors and supressing alarms via touchscreen * Escape room bomb prop where the timer can be adjusted remotely * Interface for a pallet wrapper * Taking photos and videos automatically on a running track via RFID signals * Access control via keypad or RFID chip with server code validation

This Freelancer is my worst experience, and a scammer. He will purposely do a poor job and tell you that he will fix it later. So he can ask for more money as extra time. Also be aware , he's very greedy , asking for money upfront. I went dispute with him . thank God i won and get my money back. Be careful with him, very unprofessional. I will never hire him again, even for free.
