Summary
Andrew Tsui is a Senior Software Engineer based in San Francisco with six years in mid-to-senior roles and a longer history of engineering work spanning internships to full-time positions at companies like Salesforce, LendingClub, Flexport, and Highnote. He brings a polyglot systems background (Java, C, Python, C#, PL/SQL) and a track record of shipping backend and platform services for fintech and logistics domains. With MS and BS in Computer Science (and a BS in Mathematics) from Cal Poly, he pairs strong theoretical foundations with pragmatic production experience. His career shows steady progression from internships and junior roles to technical ownership at startups and established firms, suggesting reliability in both scaling systems and mentoring peers. Based in the Bay Area, he’s comfortable navigating high-velocity product environments and cross-functional teams. A not-obvious strength is his early dual focus on math and CS, which helps him reason about complex algorithms and data integrity in production systems.
