Practical software notes from a Korean programmer and software architect in Indonesia — Laravel/Vue SaaS projects, DevOps, AI agents, and the Korea to Southeast Asia tech bridge.

I told my AI agent my blog looked like garbage. It loaded 54 real-world design systems, ran a comparative analysis, and rebuilt the entire theme with Linear.app's design tokens. Swapped between three AI models mid-task and learned which one handles structure vs. polish. 1,500 lines of CSS, 3 commits, one afternoon.
