01. About Me

Building scalable backends & elegant frontends

I'm a Software Engineer currently working as an L1 Engineer at Shadhin Lab, passionate about building things that live on the internet.

At Shadhin Lab I work with the backend team — Java Spring Boot, JPA, Thymeleaf and Docker, while also crafting UIs with React. I care about clean, well-documented REST APIs and thoughtful system design.

Beyond my day job I also build with Django, and love designing data models with PostgreSQL and MongoDB. Continuously exploring cloud-native patterns.
