What I'm looking for

I'm open to full stack work with React.js.

At PT. Moladin Digital Indonesia, I co-initiated the Loan Origination System and Loan Management System, which handle hundreds of daily transactions. I also designed and built a centralized settlement layer that brought fragmented transaction records into one auditable history.

Previously, I built Node.js microservices and APIs for transaction processing and digital banking platforms, including Jenius and DKatalis (Bank Jago). I’ve also worked on travel systems such as Aeroticket and built PHP API integrations for transportation, accommodation, and PPOB services.
