Passionate electrical engineer with my own lab. Deep knowledge of the electricity grid (I work in EV charging) and embedded systems. I have balanced the European grid by high speed (<2s response) control of 25,000 EV chargers in an operational setting with actual revenue. Could well be the largest European project to date.
Highly interested (and rather skilled) in real time control by both microcontrollers and Linux based systems using either modern interface standards or legacy ones.
Both a project manager as well as the developer. Very annoying tester (I noted the lab. Consists of good Keysight measurement equipment like oscilloscopes, vector signal generators, spectrum analyzer for high current grid work up to RF)
Programming languages: C, C++, ARM assembly, Python, Lisp, Verilog.
Embedded HW: stm32, Nordic, SiLabs, Esp32/Arduino and a bit of FPGA work.
Technologies: gRPC, Bluetooth Low Energie, OCPP, Modus, ISO15118, IEEE1901, AWS, GCP
Personal: I see myself in the basis as an engineer that builds things as well as an abstract mathematician. With all the positives that come with that combo, but I am still a normal communicator with a happy family. But I will only work on something that I understand up to the first principles. I enjoy people around me with the same mindset. Things can go really fast in that setting.
