About

A bit about
who I am

I'm a 6th-semester Informatics student at Del Institute of Technology, Laguboti, Indonesia. My passion lies in bridging design and engineering, building applications that are functional, intuitive, and scalable.

My expertise spans front-end development (React.js, TypeScript), mobile engineering (Kotlin, Flutter), and back-end architecture (Laravel, Node.js, RESTful APIs). I take pride in writing clean, maintainable code and delivering user-centric digital solutions.

Outside of coding, I serve as a Teaching Assistant for Procedural and Functional Programming, and I'm actively involved in organizational leadership on campus. I was awarded 1st Place in a Scientific Writing Competition organized by LLDIKTI Region I (August 2025).
