Top SchoolTetsuo Yamabe is a data engineer with 11+ years of experience building data platforms and product-facing ML features across education, HR tech, ad tech, and startups.

Now freelancing and building data-driven product features for an F&B startup, he repeatedly combines academic rigor with pragmatic delivery in cross-cultural teams.
