About

I build web systems — and the teams that ship them.

Software engineer with eight years of experience, two of them leading teams. I work across the stack with PHP/Laravel, React, and Python/FastAPI, for Japanese enterprise clients.

Right now I lead a five-person team building a production RAG system — AI-powered question answering over a company's own documents. I stay hands-on: ingestion pipeline, FastAPI services, vector search on pgvector, prompt design on Azure OpenAI.

I also design the engineering standards my company runs on — code review templates, coding guidelines, onboarding — and I run the training programs that go with them.

Case study

Turning around a Japanese enterprise web system

I took over a project that was already four weeks late. The codebase carried heavy technical debt, bugs kept coming back, and the client's feedback had turned into a steady stream of complaints. Nine months later we had shipped three releases in a row, on schedule, without losing a single person from the team.

The problem

4

weeks behind schedule when I took over

  • Significant technical debt across the codebase
  • High bug rate, with regressions reaching the client
  • Conflict inside the team and low morale

What I did

  • Restructured the task breakdown and reassigned work so it matched each engineer's strengths
  • Introduced merge request templates and enforced a structured code review process
  • Ran weekly alignment meetings with the PM to keep expectations explicit

The result

3

consecutive releases delivered on schedule

  • Bug rate down noticeably once code review took hold
  • Client complaints replaced by explicit praise in writing
  • Zero turnover on the team for the whole project
