About me

I'm a full-stack engineer based in Tokyo. I've been programming for over 10 years and shipping production web products for 3+, usually owning the whole thing: product design, APIs, auth, payments, analytics and operations.

Since January 2025 I've been studying Japanese at the Academy of Language Arts in Tokyo while building on the side. Being a language learner myself, I care about products that work across English, Spanish and Japanese.
