Top SchoolJiahuan He is a Software Development Engineer II with nine years of experience building reliable, high-throughput systems at scale, currently based in Old Toronto. At Amazon he has driven end-to-end features that streamlined tens of thousands of new-hire offers and audited pay rates for over a million hourly associates worldwide, including designing automated pay-rate update workflows tied to tenure and job profile. He has a track record of improving performance and operational resilience—implementing in-memory caching that made rate calculations 10+ times faster during peak wage-change events and executing complex data backfills during the 2022 stock split.

He pairs strong engineering execution with production-minded thinking about observability and auditability, and has a Computer Science degree from the University of Saskatchewan.
