About me

Sergio San Martín

My background is in electrical engineering, electronics and automation, with experience across energy systems, control and industrial technology.

Software gradually became a fundamental part of how I work. I've contributed to and helped shape more than five software projects, moving naturally between engineering, product decisions and development.

Studying and working across different countries, teams and technical environments has also shaped how I approach problems, take ownership and work with others.
