About Me
I'm a software engineer based in Khon Kaen, Thailand. Most of my web work is in React, Next.js, and TypeScript. For mobile I use Flutter, and on the backend I use Node.js and NestJS.
I've worked on e-commerce, EV charging, vehicle rental, and school administration systems. On those projects I've built customer-facing apps, admin tools, and payment integrations, along with the SQL databases they run on.
I use AI coding agents every day. When a project calls for it, I also set up MCP connections, write agent skills, and call LLM APIs from code.
