Summary

Senior🎓
Top SchoolYosuke Tomita is a seasoned software engineer with 17 years building and operating scalable web services, currently tech lead at Logiless Inc. His hands-on background spans backend development (Java, Python, Go), large-scale ad tech, API design, and log analytics, combined with deep SRE expertise in Kubernetes, Kafka, HBase and AWS. He led SRE at Chatwork—improving reliability, reducing costs and guiding an 8-person team through complex scalability challenges for a mission-critical messaging service. Yosuke brings practical datastore know-how (PostgreSQL, pgpool, HBase) and a history of driving migrations and automation to cut operational toil. He focuses on service reliability, resiliency and developer productivity while remaining actively involved in day-to-day operations rather than purely managerial work. An early adopter of Kubernetes in production, he has repeatedly translated research-level tooling (Hadoop/Hive/Pig) into production value for product teams.
