about

I'm a CS student and backend developer who enjoys building APIs and full-stack web apps. I work mostly with Java and Spring, along with JavaScript and TypeScript — with some Solidity on the side for on-chain projects.

I'm also exploring AI on the side — particularly OCR and LLMs — and how they can be integrated into real-world applications. I like systems that are small, fast, and purposeful.

When I'm not coding I'm usually exploring the Java ecosystem, exploring backend concepts, or sketching out new API ideas.

things i've done
built REST APIs in Java & Node.js
deepening Java & Spring Boot skills
built on-chain apps with Solidity
integrated local LLMs into tooling
use AI tools to speed up iteration
