Product engineer building software that stays useful.
I'm a frontend-focused product engineer in Seoul. I take rough ideas past the first version, from interface decisions to the systems that keep them running.
My independent work focuses on self-hosted tools for writing and thinking. I care about clear interfaces, deliberate product choices, and long-term maintenance.
BLEX has been running since 2019. Ocean Brain has passed 10K Docker pulls. Those are modest numbers, not finish lines. I still build, use, and maintain both products.

If you're building a product where interface quality and long-term maintainability both matter, let's talk.
