Software Engineer — |

I've always been drawn to the logic and creativity behind technology — what started as a childhood fascination with games and problem-solving became a deeper interest in how systems are built, optimized, and connected. Today I build well-structured microservices in Java and Python, and ship them end to end through Docker, Kubernetes, and Terraform.

About

I'm a recently graduated Software Engineer with hands-on experience across five backend and cloud-native roles — building well-structured microservices in Java and Python (Spring Boot, FastAPI), and working end-to-end through CI/CD, Docker, Kubernetes, and Terraform.

What drives me is the process of building things that work — not just in theory, but in practice. I enjoy digging into challenges, writing code that's clean and purposeful, and collaborating with others to bring ideas to life. Whether it's streamlining a workflow or improving system reliability, I'm always looking for ways to make an impact and keep learning along the way.

I'm especially interested in environments where curiosity, ownership, and continuous improvement are part of the culture — and I'm eager to keep growing as a backend or platform engineer.
