Full-Stack Developer — AI Automation & Web Platforms

I'm a full-stack developer based in Seoul, South Korea, with about 5 years of professional experience building web platforms and, more recently, AI-assisted automation systems.

My recent work spans browser automation (Playwright), workflow orchestration (n8n), and backend services in TypeScript, Go, and Python. A few things I've built: a Cloudflare Workers job-crawler platform with D1-backed storage, a cron-triggered collection pipeline, and Cloudflare AI-powered translation; a proxy bridging Anthropic's Claude API to local LLM servers; and a GPU-accelerated WebGL2 visualization library.

I use AI-assisted development (Claude Code) as a day-to-day tool across the whole workflow — planning, writing code, reviewing database migrations, and triaging bugs — but I treat AI output as untrusted input that I review and test before anything ships. I'm upfront about this with every client: AI helps me move faster, it doesn't replace judgment or QA.

Comfortable with milestone-based delivery and async communication across time zones. Available 10-20+ hrs/week depending on scope.

Work Terms

Based in Seoul, South Korea (KST, UTC+9). Typically online mid-morning to evening KST, but flexible for overlap with US/EU time zones — comfortable with async communication.

Prefer milestone-based payments for fixed-price work, with a working demo at each milestone before moving to the next. Open to hourly for ongoing/maintenance work.
