• Served as the primary maintainer of the open-source rust-sdks repository, responsible for end-to-end development including new feature implementation, bug fixes, and overall code quality
• Actively contributed to related SDKs such as python-sdks and node-sdks, which rely on rust-sdks as their core backend
• Designed and implemented various plugins to extend the LiveKit toolchain, including a Noise Cancellation plugin

• Led the development of the company's primary mobile application in collaboration with the design team. Built the app from scratch using React Native, managing its development, release, and ongoing maintenance.
• Designed and developed a complete redesign of the smart home system's edge computer, leading the transition from a Node.js system to a Rust-based solution. This resulted in a 90% reduction in memory usage and significantly improved the accuracy of previously unreliable timer-based functionality.

• Led the development of the company's primary mobile application, designing core functionality in Rust to ensure seamless operation across both Android and iOS platforms. Implemented platform-specific native UIs for a fully native user experience.
• Built a GraphQL API server in Rust to serve as the backend for the mobile application, ensuring high performance and scalability.

• Led the development of all divisions as CTO, overseeing backend, mobile app, and firmware development.
• Spearheaded the development of backend servers using Go, including the design, development, and maintenance of a WebSocket-based streaming server that connects all of the company’s IoT edge devices.
• Collaborated with the design team to replace the existing mobile app with a React Native solution, resolving maintenance issues caused by an outdated Android app.
• Migrated IoT devices from ESP8266 to ESP32, designing a new firmware architecture for the ESP32 generation and developing the initial firmware. Successfully obtained Echonet-Lite certification, a Japanese IoT standard for home automation devices.

Founded a prototyping and product development company focused on rapidly delivering MVPs and technical proof-of-concepts tailored to client needs. Notable projects include:

• Real-time voice communication server prototype for BONX, implemented in Go, enabling efficient group talk functionality.
• Robot conference system using Raspberry Pi with low-latency video and audio streaming, developed in C.
• Multiple React Native mobile applications, including:
  • A bike rental app supporting real-time inventory and booking.
  • A handcrafted goods marketplace app featuring seller dashboards and in-app messaging.
  • An official high school baseball app with live score updates and player statistics.

Worked across various teams to develop high-performance server-side components and cutting-edge web/mobile applications. Notable contributions include:

• Developed scalable game backends and asynchronous middleware using Perl, Go, and Node.js, with a focus on low-latency performance and high concurrency.
• As a member of the R&D team, led and contributed to the development of innovative web services and mobile applications, such as:
  • A voice-based social networking service, exploring real-time audio communication at scale.
  • A push notification API, designed for reliability and throughput.
  • Core development of Ark, a lightweight and flexible Perl web application framework, later adopted in production services.
  • Implementation of RTMP servers:
    • Kamaitachi, a full-featured RTMP server written in Perl.
    • A custom librtmp implementation in C, tailored for embedded environments.
