Senior🎓
Top SchoolYasuhisa Yamazaki is a seasoned technology leader and co-founder/CTO with 11+ years delivering full-stack, data-first platforms and cloud infrastructure across Japan. He builds hands-on products—from Snowflake-backed data architectures and serverless ETL to LLM/AI integrations—and led Srush to rapid adoption by automating analytics work from 240 to 10 hours per year for customers. A self-taught polyglot technologist, he moves quickly between roles (developer, data scientist, product manager, 3DCG artist) and prizes "safe speeding": high-quality output at startup velocity. He combines product-minded engineering with offshore team leadership and a 90% customer-feedback implementation rate, shipping features in days to weeks. Passionate about human-centered design and behavioral science, he aims to make data as consumable as content to boost Japanese firms’ global competitiveness. Unusually, he preserves work-life balance by reserving weekends entirely for family while sustaining intense short-sprint productivity.
