Summary
🤩
Rockstar🎓
Top SchoolAlexey Semjonovs is a software engineer based in Boulder, Colorado, with a strong foundation in embedded systems and four years of focused experience complemented by a long history of engineering roles at Qualcomm and Lockheed Martin. He is adept in C/C++ and building maintainable, scalable embedded frameworks, with hands-on expertise integrating RTOS components—most notably contributing to the Zephyr Project by enhancing its twister test framework, extending the west CLI, and developing sensor drivers including a generic NTC thermistor and ADC support. At Google he continues to apply his embedded and IoT skills within larger engineering ecosystems, pairing deep technical coding ability with clear interpersonal and communication strengths. Known for producing testable, agile designs, he thrives working cross-functionally to turn complex hardware-software requirements into reliable products. An understated strength is his practical focus on tooling and test automation, which reduces integration friction and speeds delivery in constrained embedded environments.
