About Me

About Me

I am a passionate full-stack developer specializing in building modern, high-performance web applications with Next.js, React, and TypeScript.

Beyond web development, I work deeply on AI integration (LLM, RAG, Prompt Engineering) and OpenClaw AI Agent framework development, helping clients bring AI into their real business workflows.

I also build cross-platform mobile apps (iOS / Android) and have Unity3D game development experience across WebGL, PC, and mobile. I use N8N extensively to connect business systems and design automation workflows.

From corporate websites, e-commerce, and admin dashboards to AI agents and games — I deliver end-to-end digital product solutions.
