I'm a Software Engineering undergraduate and Software Engineer Intern who enjoys building software across the full stack — from frontend interfaces and REST APIs to databases, QA, and deployment.
Currently I work across enterprise ERP systems, AI-assisted tooling, and cross-platform mobile apps, with a growing focus on system design, cloud infrastructure, and networking.
