About Me

Building embedded systems since 2014.

Studied Electrical and Electronic Engineering at AIUB and graduated in 2014. Throughout my career, I have engineered reliable firmware solutions for industry leaders like Walton, Teton, Riso, SOLshare, and ERROR Lab, leveraging best practices such as TDD and Git version control. Driven by continuous curiosity, I maintain a fully equipped personal electronics lab for hands-on innovation and hardware testing.
