I work beside the people doing the work.
I’m an independent software engineer based in Tokyo. From web apps to workflow automation, development foundations, and technical advisory, I support teams that have few or no engineers of their own.
About
What I do
- 1.1Web application developmentWorking mainly with TypeScript, Next.js, and Astro, from requirements to design, implementation, and operations. I also build on Cloudflare Workers and Supabase.
- 1.2Automation & DXReducing manual work with GAS, Teams bots, and internal tools, in a form the team can keep running.
- 1.3Development foundations & AITemplates, CI/CD with GitHub Actions, and IaC with Terraform, plus Claude Code workflows that standardize how a team builds.
- 1.4Technical advisory & mentoringChoosing technology for teams without engineers, and mentoring people until they can work on their own.
How I work
I work directly with marketers, sales teams, and the people doing the work to pin down requirements, then carry it through design, implementation, and deployment. I choose technology by its cost-effectiveness and by whether the people running it can manage it.
What I value most is leaving behind systems that keep running without me. Through templates, documentation, automation, and mentoring, I reduce manual work without letting knowledge sit with a single person.
