Top SchoolYen-ming Lee is a staff backend engineer with 25 years of experience building scalable payment and financial infrastructure across top tech and fintech companies. He has driven large-scale projects—from partitioning a 10B-row ledger table and 100x write throughput improvements at Coinbase to integrating multiple payment rails and scaling teams at Robinhood—with deep expertise in Java and Go-based platform engineering. His work consistently focuses on resilience, throughput, and operational simplicity for fintech use cases rather than blockchain or cryptography. Based in Kirkland, he prefers senior individual-contributor roles at publicly traded or pre-IPO companies, fully remote in Pacific time or hybrid locally, and values sane work-life balance over 996-style schedules. An engineer who blends hands-on systems optimization with pragmatic product delivery, he selectively engages only with opportunities that include detailed job scopes and appropriate seniority.
