Summary
👤
Senior🎓
Top SchoolRyo Nakagawara is a data scientist based in Tokyo with 10 years of experience building reproducible analytics, ETL pipelines, and R-based tooling for international development programs at ACDI/VOCA. He combines hands-on software development in R and SQL with product-focused outputs—R packages, Shiny apps, dashboards and automated reports—that drive monitoring and decision-making across global projects. Outside the NGO sector he consults on Japanese football analytics, runs the "Shogun Soccer" newsletter, and has contributed to notable open-source R packages (co-author of ggshakeR, author of tvthemes). His background—an MSc (Distinction) from UCL, international work across Ghana, India, Germany, the US, Ireland, the UK and Japan, and active leadership in the R community—makes him adept at translating complex data into actionable insights for diverse stakeholders. An often-overlooked strength is his stewardship of an entire R codebase and release-ready package ecosystem that keeps operational analytics resilient and reproducible.
