Summary
👤
Senior🎓
Top SchoolTengis B is an Engineering Manager in SRE based in Mountain View with nine years of hands-on experience building cloud-native infrastructure and fintech platforms across Asia and the US. He has led cross-geo teams at Mercari, evolving Kubernetes-based microservice platforms, improving observability, and practicing fin‑ops to balance reliability with cost efficiency. Previously he owned core payment microservices, drove zero-downtime legacy migrations, implemented chaos engineering, and shipped P2P transfers and credit features—demonstrating both product-facing impact and deep operational discipline. Comfortable in polyglot environments (Go, Node.js, Python) and with infrastructure-as-code, he combines developer-friendly platform building with security and scalability stewardship. A global perspective informed by studies in Korea and Mongolia and a hacker’s mantra of “try. break. build. enjoy.” make him both pragmatic and curious in solving complex systems problems.
