What I'm looking for

I want to build reliable, scalable backend systems in Agile teams—focused on clean code, testing, and performance. I’m happiest owning services end-to-end, improving latency and monitoring, and mentoring teammates while delivering measurable business outcomes.

I’m a Backend Java Developer with 4+ years of experience building and maintaining Java Spring Boot systems. At Bank Negara Indonesia (BNI), I delivered critical lending features—installment conversion, credit card activation, cash fund disbursement, insurance integration, credit limit adjustments, and loyalty point systems—while mentoring 2 junior developers and strengthening our clean-code, testing, and performance culture.

I enjoy working across the backend-to-integration layers: I migrated services using reactive WebFlux to improve API latency for 50K+ daily users and integrated Kafka for real-time streaming with faster incident response. I’ve also supported Sharia-compliant insurance platforms at Prudential Syariah and built secure API governance and insurance integrations using webMethods and 3scale on OpenShift, plus hands-on fintech payment development with Xendit & Durianpay.
