A little about me

I am a final-year Computer Science student at Institut Teknologi Bandung and a full-stack engineer. At Paper.id, I spent a year building reporting and invoice workflows in Go, Angular, and PHP for enterprise clients.

I like work where product decisions and system design meet. That has ranged from an orientation platform used by 5,000+ students to teaching full-stack development and Java object-oriented programming to hundreds of ITB students.

I work best when I can understand a system deeply, make the trade-offs explicit, and leave the next person with code and explanations they can trust.

Selected work

Three projects, chosen for different reasons: shipped scale, systems depth, and product impact.
