Summary
👤
Senior🎓
Top SchoolKevin Liu is a senior software engineer in San Francisco with 9 years of experience building scalable distributed systems and cloud infrastructure. He has a strong track record shipping production services using Python and Ruby, from high-throughput APIs at Apple to mission-critical data pipelines and ingestion services at Convex and ServiceTitan. Kevin has driven measurable efficiency gains—90–100x query optimizations and a 92% Airflow runtime reduction—and led a team that generated roughly $1M ARR through custom integrations. He pioneered infrastructure-as-code and containerization practices, and bootstrapped microservices that enabled multiple daily releases without impacting core systems. Comfortable with both backend systems and data engineering, he also brings applied math training and hands-on data science experience from Galvanize to inform robust, data-aware designs. Colleagues rely on him for pragmatic, high-impact engineering that turns messy migration and integration problems into repeatable products.
