Summary
👤
Senior🎓
Top SchoolAndy O'neill is a Principal Software Engineer with 13 years of experience building distributed systems and cloud backends across health tech, e-commerce, IoT, climate, and property tech. He blends hands-on coding with technical leadership—founding teams, architecting service-oriented platforms, and shipping customer-facing products from early-stage startups to scale. Recent work includes architecting FHIR-interoperable patient engagement systems and building the cloud backend for an AI-driven hearing aid, while past roles span core platform and reliability work at Harry's and embedded/IoT systems at EnergyHub. Comfortable in Python, TypeScript, Scala, and embedded C/C++, he still prefers to be “in the weeds” coding while coaching teams. His PhD in astrophysics underpins a rigorous approach to simulation, data analysis, and complex-system thinking that shows up in both product design and observability work.
