A bit about me

I'm a final-year Computer Science student at BINUS University and a Software Engineer Intern at Moladin, where I work in a cross-functional team on the Risk Intelligence System — async scraping, OCR + LLM document extraction, and the services around them.

Outside work I ship my own products end-to-end: Playfield, a real-time matchmaking platform for racket-sport communities, and DearNote, a SaaS for personalized digital letters. When I'm not building, I'm probably watching (or playing) badminton.
