About Me

Hi, I am Tomas Ospina Martinez :wave:,
an Electrical Engineer working at the intersection of circuit design, PCB validation and intelligent automation. My hands-on work covers circuit analysis, schematic interpretation and PCB design/validation with EDA tools — KiCad, Eagle and Altium Designer — and I have taken circuits from schematic to working hardware on my own projects, catching design errors and validating behaviour before deployment.

That hardware base sits alongside firmware and systems work: real-time embedded development in C/C++ on ESP32 and STM32, and Python automation that turns manual operational bottlenecks into traceable, reproducible workflows. Having diagnosed hardware faults on an autonomous robot fleet in the United States and communicated findings directly to clients in English, I am comfortable working from technical documentation and explaining what I find to people who need to act on it.
