I like the messy middle of consumer products — where engineering, product, and growth all pull in different directions, and the real work is figuring out what actually moves.
For the last few years I’ve been working on subscription and growth surfaces at Wolt (DoorDash) in Tokyo — owning parts of the funnel end-to-end, from entry points in cart and checkout through signup and retention. The work is rarely about building a single feature. It’s about breaking problems into experiments, removing friction, and shipping changes that measurably improve conversion, order volume, and retention.
Before that I spent four years at SmartNews shipping to millions of users, working across onboarding, feed, and server-driven UI. Before that, five years at Bodybuilding.com — where I grew into the role by taking ownership early, shipping full features, and learning what 60fps actually feels like under load.
Across all of that, the pattern is the same: I tend to end up close to the surface where product decisions and engineering reality meet — figuring out how to simplify flows, make systems behave predictably, and get changes shipped and measured.
Right now I’m going deeper into AI-native product work with Aside — a macOS app for AI-driven mock interviews. It’s less about “learning AI” and more about building real systems: orchestration across models, real-time speech pipelines, and retrieval over session context.
What I'm good at
Owning consumer features end-to-end. Reading a funnel and finding the four pixels of friction nobody’s looking at. Breaking large efforts into shippable experiments. Migrating and evolving iOS codebases without slowing the team. Building telemetry people trust enough to act on.
What I'm learning
How to build AI systems that behave reliably in real products — not just demos. Orchestration, evaluation, and where the edges actually are.

I live in Fujisawa, near the ocean south of Tokyo, in a house designed around airtightness, solar, and a V2H-equipped EV. Two young daughters. A very patient wife. Cycling year-round, snowboarding in winter, and re-learning to skateboard. Still imagining the day I finally start surfing.
