About AGATRONIK

AGATRONIK stands for tailor-made electronics and software solutions – developed with passion, technical precision, and many years of experience.
Whether working independently or together with experienced partners from specialized fields, I support projects from the initial idea to the fully functional product.

I work with modern, preferably open-source-based tools such as LTspice, KiCad, the .NET Compiler Platform SDK, Visual Studio Code, STM32CubeIDE, Atmel Studio, Arduino, as well as version control with Git and SVN.
My aim: technical solutions that not only work – but reliably stand out in the long term.
