I'm a backend software engineer with experience designing scalable microservices and API workflows — especially in cloud-native environments using Python, Flask, Django, and Google Cloud Platform.

Currently, I'm expanding into Java and thoroughly enjoying the Spring Boot ecosystem and object-oriented design principles. I value clean, maintainable, and elegant code, and love learning how different languages and frameworks approach software architecture.

While backend is my core strength, I'm also growing toward a full-stack skill set. I'm actively building projects with React and reinforcing my frontend fundamentals in JavaScript and TypeScript.

Whether it's building robust APIs, integrating AI workflows, or creating smooth user interfaces, I enjoy solving real-world problems through thoughtful engineering.
