About

I'm a software engineer based in Seoul. I build consumer products and the infrastructure that runs them — Android, web, backends, and increasingly the CI/CD and observability that holds it all together.

I've shipped a profitable English-learning app solo (100K+ downloads), contributed to Hono.js, published an OSS payment library used in production, and am currently the tech co-founder of a live-commerce translation startup pushing real-time multilingual video through AWS Fargate.

My engineering values are pragmatic. I favor clean architecture because it keeps debugging cheap, testing at three tiers because bugs hide between layers, and observability because production is the only place that matters. I don't over-engineer — ship, measure, iterate.

What I take on

Contract work with product teams that need mobile done properly: shipping an Android app end to end, porting an iOS app to Android, rescuing a release that is stuck, or building the backend behind it.

Full-time roles too, when the product and the team are right.

I hold an F-2-7 resident visa, so I am work-authorized in Korea and can take on contract and freelance work without a sponsor. Korean is a work in progress.

Background

• Coding since 2019, full-time professional since 2020
• Previous: StoneLab (Android + mobile + frontend, Seoul)
• Before that: CodemyUz (2020, Uzbekistan)
• Side projects: Spiko English (solo), Brivva Tech (co-founded, now open source)

Beyond code

I use NixOS + Obsidian + terminal-heavy workflows. I read more than I write. I'm slowly building a Korean vocabulary that will, one day, let me stop apologizing in English at the convenience store.
