Senior🎓
Top SchoolPiece Chao is a Senior Backend Engineer with 11 years' experience designing high-performance, cost-efficient backend systems for e-commerce, live streaming, and ride-hailing platforms. He excels at diagnosing and eliminating database and Redis bottlenecks—reducing query latencies from ~900ms to under 100ms and cutting RDS costs by 50% during peak traffic. Piece has built distributed dispatch architectures, multi-environment AWS VPCs with zero-downtime RDS blue/green migrations, and centralized multi-country product databases supporting global storefronts. Comfortable across PHP, Node.js and Go, he combines hands-on optimization (indexes, Redis data structures, persistent connections) with CI/CD automation and observability via Datadog and GitHub Actions. Based in Taoyuan City, Taiwan, he pairs practical system refactoring experience with a knack for translating business requirements into scalable, operable backend designs.
