Summary

Rockstar🎓
Top SchoolJames Haggerty is a Senior Software Engineer based in Sydney with 13 years building embedded, web and backend systems across startups and product teams. He’s shipped production software at Atlassian and Grok Academy and now focuses on wireless/semiconductor engineering at Morse Micro, combining low-level embedded skills with higher-level service design. Comfortable across C, Python and modern web stacks, he also contributes to hardware-adjacent open-source projects—most notably enhancing an F-91W-compatible Sensor-Watch with TOTP, RPN calculator and filesystem-based secret storage. His background includes research-grade spatial databases and teaching, which gives him a pragmatic but methodical approach to tooling and documentation. Colleagues rely on him to bridge firmware, build systems and cloud APIs, and he’s the sort of engineer who’ll happily explore FPGA ideas when a CPU won’t do.
