Summary
👤
SeniorKun Zhou is a software engineer based in San Francisco with nine years of experience building resilient database infrastructure and distributed systems. He has driven large-scale data projects at Airtable and Stripe—shipping a petabyte-scale MySQL-to-S3 archival system, productionizing CDC with Apache Flink, and resharding billions of records to enable multi-regional availability. His work repeatedly targets operational pain points: slashing MySQL replication lag to sub-second, automating risky DDL migrations, and reclaiming over $1M in annual cloud costs. At WePay he moved onboarding to a session-based microservice architecture and sped local builds by 80%, showing a knack for developer experience improvements as well as data plumbing. Now at Sierra, he continues to focus on reliable, cost-effective storage and serving layers that keep high-throughput services online. Colleagues describe him as deliberately private yet consistently impactful—preferring technical craftsmanship over fanfare.
