Senior🎓
Top SchoolJohn Hritz is a Principal Firmware Engineer with a decade of hands-on experience designing and shipping embedded systems for medical and consumer products from Hayward, CA. He currently leads firmware development for an orthopedic surgical table and has a track record modernizing legacy firmware, integrating new sensors (UWB, IR temperature) and supporting cloud-adjacent data infrastructure for pet-health devices. Equally comfortable in C/C++ and Python, he pairs low-level device work with CI/CD, data analytics, and field testing to turn prototypes into reliable products. A compulsive problem-solver and builder, he brings practical hardware fluency from freelance prototyping to production teams, and often surfaces non-obvious improvements in system flexibility and testability.
