Summary

Rockstar🎓
Top SchoolWilliam L is a software engineer based in Sydney with seven years’ experience building high-performance search and machine learning systems. He improved search relevance and recall at Atlassian—leading an experimentation platform that delivered a 31% recall gain—and raised end-to-end QA precision for a conversational agent from 55% to 89%. His background spans production engineering (smart load balancers, caching microservices, page-load optimisations) to applied research, including graph-minor-embedding heuristics for quantum annealing and embedded flight-control software for a nanosatellite. He has a strong practical streak: shipping field-facing AgriTech features that saved farmers hours a day and delivering a 9x GPS accuracy improvement through custom test rigs. Pragmatic, research-savvy, and results-oriented, he thrives on squeezing more signal out of data and infrastructure at scale.
