Who is Jin Kobayashi? Head of testing at Food Tracker Compass
Head of testing & ML engineering
MS Computer Science, Carnegie Mellon · Tokyo, Japan · he/him
Jin runs the daily testing lab at Food Tracker Compass. He wrote the harness that drives every benchmarked app through the same 36-dish cross-check on real devices — twelve iPhones, eight Pixels, two iPads — and the dashboard that compares median-time-to-log across photo, search, voice and barcode paths. He spent four years on Stripe’s machine learning platform and three years on Snap’s AR camera team, where he learned how mobile latency and recognition quality actually trade off in production. He owns the comparative reviews on the site and most of the head-to-head comparison pages.
