What I'm looking for

I'm looking to build reliable full-stack products and automation systems, collaborate closely with engineers and product teams, and keep growing through challenging client-facing work.

I've delivered and maintained full-stack web applications for One Terrace Japan across five enterprise and commercial clients, including JP-MIRAI, KPMG Japan, Taiheiyo Consultant, Toshin Language School, and One Terrace.

Across eight projects, I contributed to system design and development for real-time communication, calendar scheduling, authentication, user management, and business workflows. I also resolved production performance bottlenecks, memory leaks, and UI/API defects where reliability and minimal downtime were critical.

At KBTG, I develop Maestro automated test cases and regression suites for the K PLUS mobile banking app, collaborating with QA engineers and developers to expand coverage and investigate failures.

I've also shipped WDTM, an AI-powered Chrome extension with 40+ installs, launched the open-source Hermes OmniVoice Python TTS plugin, and co-authored a JCSSE 2026 paper comparing five image-segmentation techniques across 500+ mango images.
