About

What I do

I'm a Software Engineer with a focus on Java, passionate about automation and building complete, reliable systems. I enjoy developing and maintaining end-to-end solutions from backend services and APIs to frontend features, infrastructure, and CI/CD. While Java is my main language, I also like working with JavaScript and keep experimenting with practical tools that deliver real business value. Lately, I enjoy experimenting with AI, building agent flows and pipelines, and using and building MCP so development stays more productive, clean, and maintainable.
