Masataka Shintoku
Tokyo, Japan
Summary
👤
Senior🎓
Top SchoolMasataka Shintoku is a product-focused engineering leader with 15+ years of experience building resilient, user-centered systems across government, enterprise, and startups from Tokyo. He combines hands-on full‑stack development (TypeScript, Go, React, Next.js, GCP/AWS, Terraform) with product strategy and UX practices to turn messy legacy codebases and hardware-constrained IoT problems into shipping products and compliant platforms. As an early private-sector engineer at Japan’s Digital Agency he helped deliver a national payment service (PCI‑DSS) and an HR app that saved 1,800 hours annually, and he has repeatedly proven an ability to scope feasible PoCs where stakeholders expected failure. He’s scaled teams from zero, introduced IaC and testing culture, and translated technical ideas for executives and cross-cultural audiences—evident in his work localizing bootcamps and translating a Bitcoin programming book into Japanese. Pragmatic, evidence-first, and bilingual, he focuses on integrating global best practices into Japan’s context while remaining curious about philosophy, meditation, and the quiet craft of a good morning coffee.
