Summary
👤
Senior🎓
Top SchoolMotomu Ohtsuki is a seasoned software engineer based in Mountain View with 11+ years of hands-on experience building high-throughput, scalable backend systems across ad tech and cloud-native environments. At Google he’s driving a migration from SQL-based monetization pipelines to map-reduce architectures, and earlier at Criteo he tuned a real-time bidding backend to handle 570k+ QPS while multiplying A/B testing capacity fivefold. Comfortable across Golang, PHP, Java, Python and a broad data stack (Kafka, Redis, MemSQL, Spark, Aerospike), he has a track record of reducing latency and CPU usage through careful profiling and concurrency fixes. He also brings full-stack infrastructure experience—Docker, Kubernetes, AWS/GCP—gained from building production systems and developer CI environments. Notably, he won reliability and performance gains by eliminating online cache server hits via in-process synchronization, a pragmatic optimization that reflects his focus on measurable impact.
