Rockstar🎓
Top SchoolRoger Chapman is a Principal Architect and polyglot engineer with 15+ years building low-latency, high-scale systems and shipping mobile and web products from startup to enterprise. He blends deep systems expertise in Go, gRPC, C#, Objective‑C and Java with front-end mastery (React, WebRTC, WebGL) and a hands-on performance-first approach to networking, memory and profiling. At SafetyCulture he drove company-wide language, API and release-process shifts—making Go and gRPC primary—while serving as the sole Distinguished Engineer for a 200+ engineer organisation. He is an active open-source contributor (notably to v8go and iOS Nimbus) and has published multiple apps to the App Store and Play Store. Based in Sydney, he pairs pragmatic architecture with product sensibility, often surfacing non-obvious optimisations around request batching, caching and protocol design to unlock real-world scale and responsiveness.
