About Me

I've been shipping code for 7+ years. I'm a Full-Stack Developer who builds real products with TypeScript, React, Node.js, and AWS. I've worked across retail, IoT, telecom, and SaaS—building everything from frontend interfaces to backend systems to cloud infrastructure.

Right now, I'm learning AI and automation. Not as a consultant selling AI services, but as a developer who wants to integrate these capabilities into the things I build. I'm experimenting with Claude APIs, Abacus assistants, and agentic patterns—learning by doing.

My approach is simple: build solid software with proven technologies, then explore how AI can make it better. I'm not overhyping AI or claiming to be an expert. I'm a developer who ships code and is actively learning new capabilities.

I'm looking for projects where I can contribute as a full-stack developer and potentially integrate AI features. If you need someone who can build reliably while exploring what's next, let's talk.
