Summary
👤
Senior🎓
Top SchoolTsung-en Hsiao is a Tokyo-based software engineer with 12 years of professional experience and about 7 years focused on backend development, cloud networking, and payments systems. He has driven cross-team refactors, data migrations, and performance tuning at scale—most recently improving API p99 latency and payment error rates at PayPay and now contributing to BBPOS under Stripe. His background blends hands-on backend Java/Kotlin and Spring Boot work with deep operational expertise in GCP networking, CDN, Redis, and MySQL diagnostics from roles at Google and startups. Comfortable leading projects end-to-end, he’s been the go-to person for cache and CDN incidents and has led major refactors requiring careful backward compatibility and coordination. Fluency in Japanese-enabled engineering in Japan and a history of building and migrating complex e-commerce and payment workflows give him a rare mix of product sense and low-level systems debugging skills.
