Professional Summary
I work on embedded systems and software that need to be reliable—from research stations in Antarctica that run unattended for years, to DC fast chargers pushing 360kW, to control systems that keep industrial equipment running. My experience spans autonomous data collection on Thwaites Glacier, EV charging development at companies like Nidec and Eaton, open-source contributions to charging protocols, and participation in IEEE technical committees. What keeps me engaged is solving real problems. Sometimes that means fixing bugs that are causing support issues, sometimes it's helping engineers work through complex integrations, and sometimes it's testing high-voltage systems to understand their behavior. Through debugging CAN bus protocols and managing satellite data links, I've learned that good engineering isn't just about the code—it's about understanding what needs to work and making sure it does.
