I'm a software engineer focused on desktop application development with WinUI 3 and C#, alongside embedded systems (esp32) and full-stack development (NestJS + Vue.js). My work spans from building high-performance ground station software for satellite and rocket tracking to developing ESP32-based IoT systems and scalable web applications.

Currently at ELM Inc., I specialize in crafting efficient Windows desktop applications that demand real-time performance, clean architecture, and reliability — while also working on firmware for ESP32, full-stack web applications, and mobile app development as needed.

Work Experience

Software Engineer II

Jan 2026 — Present

ELM Inc. · Kagoshima City, Japan

Desktop Development Algorithm Python

⬤ Reduced CPU usage by 80% by architecting a ground station desktop application in WinUI 3 (C#) supporting satellite tracking via TLE propagation and rocket tracking across three modes (Program, Auto, Monopulse) while improving real-time telemetry visualization and responsiveness.

⬤ Reduced print time by 50% and material costs by 90% by designing a cylindrical slicing technique in Python for support-free 3D printing of a 2.4m parabolic antenna.

Software Engineer I

Jul 2024 — Dec 2025

ELM Inc. · Minamisatsuma City, Kagoshima, Japan

Embedded Systems IoT Python Mobile Development

⬤ Built the source module for an IR audio data streaming system on ESP32, handling multi-source audio capture (analog mic, Bluetooth, SD card) with real-time PWM streaming and low-latency processing.

⬤ Developed a Raspberry Pi-based night-vision system in Python using IR cameras to detect wild boars and automatically trigger deterrent lighting, reducing crop damage.

⬤ Built a .NET MAUI cross-platform mobile app enabling BLE communication with ESP32, featuring device discovery, QR-based pairing, and real-time data transmission.

Selected Projects

UNISHARE

Developed and maintained a RESTful backend for a university student rental marketplace, supporting property listings, management features, Stripe payment processing, and automated student verification through university ID validation.

Next.js Spring Boot PostgreSQL

Online Exam Proctoring

Implemented an automated online exam proctoring system that continuously monitors examinees’ eye movements and activity. Detects attempts to switch exam tabs or look away from the screen beyond teacher-specified limits, and alerts the teacher with supporting evidence such as camera footage and screen recordings.
