About
Software experience, heading down to the hardware.
I started working young, and it shows in how I work: professionally, reliably and comfortable with responsibility. What began as a summer job in a large warehouse for kitchen appliances turned into a permanent role as weekend shift lead. From there I moved into the IT department, where I build internal .NET applications that support and automate the logistics.
Now I am taking that software experience down to the hardware: microcontrollers, industrial IoT and robotics. I like the whole chain, from the firmware on an ESP32 to the service and the container it reports to.
I work well in a team and get things done on my own. Outside work and study I play football at VVS’46 and head to the mountains for winter sports whenever I can.
