About Me

I am a software engineering student with a strong focus on building practical, production-ready systems. I enjoy working at the intersection of backend development, cloud platforms, and security - where performance and reliability matter.

My approach is simple: build systems that are secure, scalable, and actually usable in the real world.

Outside engineering, I love cooking (especially Asian cuisine), watching all types of sports, and bringing a fun, energetic, and always-happy attitude to what I do.

I have worked on projects ranging from data pipelines and full-stack applications to secure backend APIs and cloud-based architectures, both independently and in team environments.
