At OY! Indonesia, I build and maintain end-to-end fund disbursement services for transaction processing, multi-vendor routing, automated failover, and cross-border remittance.

I increased bulk disbursement throughput by 75% through concurrent batch processing and reduced query processing times by 40% through database optimization. I also support 99.9% uptime through on-call incident response, production monitoring, and robust transaction APIs.

I've also built Android, full-stack, and frontend products, including a Kotlin-based SuperAgree app, an SPM quiz platform with AI study recommendations, and WebGIS census applications. I enjoy building scalable systems that connect payments, data, and real-world user needs.
