About me

I'm a Full-Stack AI Developer passionate about building modern web solutions. I specialize in Next.js, React and TypeScript on the frontend, and .NET and Node.js on the backend.

I'm particularly fascinated by AI and automation. I build intelligent agents using LangChain and LangGraph that help businesses automate processes and increase efficiency.

I believe technology should serve people. That's why I focus on creating solutions that are not only functional but also intuitive and enjoyable to use.
