Founder & Solo Developer at GRAXEL

Solo developer building and operating GRAXEL. I design SaaS monorepos with Next.js, Rust, and Python — running services like MyHyetaek (RAG for Korean government benefits), JobFit (AI recruiting), and K-Guide (Korea life guide for foreigners) end-to-end. Since starting GRAXEL in December 2025, I have been documenting how a single-operator stack on Cloudflare Pages, Oracle ARM, and Thunderbolt 5 networking handles real production traffic at near-zero monthly cost.
