Indonesia

Message

At DANA, I developed products including Velo, S-Mart, and BoraMart, and received the 2023 MVP award for Velo. I implemented product and order search with Meilisearch and optimized a batch sync of about 14 million records from roughly 60 seconds to 180 milliseconds.

At Moka (Gojek / GoTo Group), I led the design, implementation, and testing of Partner Service for connecting Moka outlets with GoBiz. I also contributed to migrating Moka POS from Ruby on Rails to Java Spring Boot microservices.

Earlier, at TEXO, I developed backend APIs for e-wallet, payment, merchant, and biometric services using Go and Java. My work has also included financial products at DOKU and Java web applications and reporting systems for enterprise clients.
