About Me

I'm a software engineer with 4+ years of experience building full-stack applications and enterprise-grade systems. Currently based in Germany, I work at K Line Europe GmbH where I design and ship production management tools used daily across 10+ teams on the factory floor.

My stack spans Next.js, React, Node.js, and PostgreSQL on the application side, backed by hands-on experience with AWS, Docker, Kubernetes, Terraform, and CI/CD pipelines on the infrastructure side. I care about writing clean, maintainable code that solves real problems at scale.
