I'm a Full-Stack Software Engineer who builds web applications with TypeScript, Next.js and Node.js, and adds practical AI features to them: chat with your documents (RAG), streaming assistants and structured AI output. I work across the stack, from responsive interfaces to APIs, PostgreSQL and MongoDB databases, authentication, testing and deployment.

I enjoy turning ideas into practical software with clean code, thoughtful architecture, and a strong focus on user experience.
