Sotaro Ichii · Statistics, UC Berkeley

Turning messy data into systems people can rely on.

I'm a Statistics student at UC Berkeley who builds data pipelines and web products end to end, from ingestion and normalization to deployment. I co-founded IDEAVALU, a launch platform for Japanese indie developers, and I'm on a CITRIS research team mapping Physical AI in healthcare. Native Japanese, business-fluent English.

01About

The rigor of a statistician, the ownership of an engineer.

I study Statistics at UC Berkeley's College of Computing, Data Science, and Society. Before transferring in Fall 2026, I studied computer science at Orange Coast College (GPA 3.82, President's List).

Most of what I build starts with messy data: listings from five platforms with different formats, external API feeds, and product usage logs. I enjoy the unglamorous work of making that data consistent, testable, and trustworthy, then measuring whether a change actually worked and reporting the result honestly, even when it is negative.

As a native Japanese speaker with business-fluent English, I've built products for users in both Japan and the United States.

What I bring

01

Data engineering

Ingestion from APIs and web sources, normalization of inconsistent data into consistent, queryable formats, and automated reporting.

02

Statistics and analysis

Coursework in probability, statistical computing in R, and data science, applied to product questions such as retention measured in production SQL.

03

Full-stack product development

Built and launched a production platform on Next.js, TypeScript, Supabase (Postgres), and Vercel with a team of four, and keep it running for real users.

04

Evidence-driven communication

Hypothesis-driven iteration measured in production data, with findings explained clearly to non-technical stakeholders in English and Japanese.

IDEAVALU

Live

Launch platform for Japanese indie developers

  • Built and launched the platform with a team of four on Next.js, TypeScript, Supabase (Postgres), and Vercel.
  • Built an ingestion pipeline that collects items from Hacker News, Product Hunt, GitHub Trending, Zenn, and Qiita, and connected GA4 and Postgres usage data to automated Slack reporting.
  • Measured retention in production SQL (83% of makers posted once and left), shipped three interventions, and re-measured. A proxy metric rose 6.4x but retention did not move, so I reported the negative result and moved on to the next hypothesis.

Code activity

Most of my production code lives in private repositories, so this activity includes work that is not publicly visible. I am happy to walk through code on request.
