About

Senior Software Architect with 35+ years of experience. I specialize in breaking technological barriers—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. I am a master of Swift and C#, delivering high-quality code through high-speed asynchronous, text-only communication. I excel at rescuing failing projects and redefining architectural standards.

WPF
.NET
Windows Application
A lightweight Windows desktop utility built with C# and .NET 8 that integrates the IME (Input Method Editor) status into the system clock. It solves the common friction of unintended language input for bilingual professionals. Key features include zero external dependencies, high performance, and a clean MVVM architecture.
