02 · Captain's note
Built in Makassar, shipped anywhere
I graduated in Informatics Engineering from Universitas Muslim Indonesia with a 3.86 GPA. Over the past two years I have built web applications with the MERN stack, Next.js, Python/Flask and PHP/Laravel, plus Android apps in Kotlin.
Right now I build and maintain internal platforms and dashboards at PT Aptana Citra Solusindo. Before that I delivered an IoT monitoring dashboard that is used in daily airport operations at Angkasa Pura Indonesia, and web systems for small-business clients.
On the Web3 side, my thesis put zero-knowledge proof generation on an Android phone talking straight to Polygon smart contracts. It was published as a journal article.
