At BukuWarung, I deliver lending and payment products, including KYC/KYB flows and an automated lending flow processing 1,000+ loans each month. I also built a standalone EDC order flow that processes 2,000+ agent orders monthly and own the architecture, delivery, and maintenance of webviews for the BukuWarung and BukuAgen apps.

I've led a TanStack Start migration that reduced CI builds from 12–22 minutes to around six minutes while improving API credential security. Across fintech, e-commerce, and client projects, I build frontend products with React, Next.js, and TypeScript, with backend experience in Node.js, Express.js, Laravel, and Java.
