Tokyo-based software engineer working on large-scale infrastructure and developer tools.
I’m Alfred, a software engineer and open source software enthusiast with over 10 years of experience designing scalable, high-performance systems and leading cross-functional, multi-regional development teams.
Today I work across cloud infrastructure, distributed systems, and developer tooling. I have an extensive background in building end-to-end video platforms and media processing pipelines delivering low-latency streaming video solutions to millions of end users.
Video is still where I spend my own build time. I’m the creator of Video Commander, a desktop app for video engineers, along with a handful of open source video and FFmpeg tools used by thousands of developers.
I'm based in Tokyo, Japan. My career spans cloud, video, and backend systems across global engineering teams, including Comcast NBCUniversal and Sky UK.
