Top SchoolAlfonso Garcia-caro is a senior full-stack engineer based in Japan with over a decade of experience designing high-availability systems and data-driven applications across finance, biotech, renewable energy, and more. Creator of the Fable compiler (F# to JS/TS/Python/Rust) and a contributor to the core F# ecosystem and language server, he blends deep open-source compiler work with pragmatic engineering for enterprise BI and ETN product tooling. At Nomura he engineered end-to-end ETN management systems and executive Power BI dashboards, while his consultancy portfolio spans genome-data handling, real-time media, and high-throughput logistics systems. Comfortable across cloud CI/CD, complex ETL, and legacy-modernization challenges, he is bilingual in Japanese and English and excels at translating domain complexity into resilient, automatable solutions. An unexpected strength is his background in language research and localization, which informs his attention to tooling, documentation, and developer UX.
