About
Senior Software Engineer with 35+ years of experience. I solve complex problems that others gave up on — from proposing the "Engine-on-Wing" configuration for the HondaJet to independently developing the core UI for the world's first HDD-integrated DVD recorder at Panasonic.
What I Solve:
• Complex debugging that other teams gave up on
• Failing projects that need rescue and stabilization
• Cross-platform consistency (macOS ↔ Windows)
• Legacy system modernization
I am a master of Swift and C#, delivering high-quality code through async-first communication (Slack, email, GitHub). Open to voice/video meetings when needed for design discussions or team sync. I excel at rescuing failing projects and redefining architectural standards.
Work Experience
Providing high-level architectural consulting and full-stack development for major Japanese enterprise clients and open-source projects.
• Modernization & Rescue: Rescued multiple failing large-scale Java projects for critical infrastructure (Power, Securities, Public Services), improving performance and maintainability by redefining system architectures.
• Cross-Platform Expert: Developing native desktop utilities (IMEIndicatorClock) using Swift for macOS and C#/.NET 8 for Windows, prioritizing zero-dependency and high performance.
• Async-First Collaboration: Delivering through clean code and clear documentation via Slack, email, and GitHub. Open to voice/video meetings when needed for design discussions or team sync.
Led the solo development of the core User Interface for the world's first HDD-integrated DVD recorder (DMR-HS1).
• Mastered complex international DVD standards (English-only documentation) within 2 months to architect the system from scratch. • Independently designed and implemented critical HDD-DVD dubbing functions, bypassing inefficient organizational structures to deliver a high-quality product on a tight schedule. • This project established the foundational UI architecture for a new generation of consumer electronics.
