Summary
👤
Senior🎓
Top SchoolDavid Zhang is a web engineering leader with 12 years of experience building reliable, high-scale web platforms and automation tooling, currently leading Reliability, Automation & Tooling for Cash App’s web stack. He has deep expertise in CDN-layer security, rate limiting, and full-stack continuous deployment systems that operate across billions of daily requests and multi-CDN environments. Prior roles at Snap, Scale AI, and others show a track record of designing scalable product catalog services, integrating ML-powered extraction and observability, and migrating monoliths to robust microservice and IaC-driven architectures. David blends hands-on engineering with program-level coordination—organizing web summits, producing tech talks, and embedding AI agents into developer workflows to boost productivity. He’s comfortable across languages and systems (from JVM frameworks to Temporal, BigQuery, and Cloud infra) and has a Waterloo software engineering background with a pattern of improving reliability and developer velocity. An under-the-radar strength is his knack for shipping pragmatic instrumentation and monitoring that turns ambiguous outages into actionable, automated responses.
