Full-stack Web Developer
I am a full-stack web developer working primarily with JavaScript, especially Next.js and Astro.
I am currently expanding into AI engineering through hands-on work with automation, AI agents, RAG, and AI-powered web applications. I use this site to share the projects I build and what I learn along the way.
