ABOUT ME

Programming since I am 8 years old, I made my hobby my profession.

I worked in many different fields from high resolution graphics processing using C++ over backend infrastructure implementations for large web-providers to writing medical software for a portable MRI machine. I mostly spent my time writing backend or embedded software, which is where I have the most expertise. I know the basics of front-end web development too, but I would not consider myself an expert in that field.

fully implemented LLRP (low level reader protocol) to communicate with multiple RFID readers. Software ran on a passively cooled low power industrial PC, aggregated the data and sent it to RabbitMQ for processing on the backend. Backend based on Django, with custom SQL queries for faster statistics processing.
