Summary
👤
Senior🎓
Top SchoolRitsuki Kokubo is a pragmatic data engineer with eight years’ experience building end-to-end systems across manufacturing, web, mobile, game, and IoT domains. At ミイダス株式会社 he drives data reliability and democratization for a ~2,000-table analytics platform, building ETL, a tbls+Docusaurus data catalog, and automations that cut BI onboarding and permissions work. Previously as an in-house SE in manufacturing he delivered Android handheld apps, OPC/time-series collection pipelines, and custom BI plugins—often iterating UI with Figma to ensure operator adoption. He also ships solo hobby projects (Go/Unity online games and SwiftUI iOS apps) end-to-end from concept to store release and monetization, giving him product-minded engineering instincts. Comfortable from legacy .NET maintenance to modern Python/TypeScript/Go stacks, he leverages AI coding agents (Claude Code, Copilot) to accelerate specification-driven development and rapid prototyping.
