I've built production backend systems for Careem, POS Malaysia, Hijra Bank, Traveloka, and Indonesian telecom and manufacturing companies. My work spans dispute resolution, vehicle renewal, KYC onboarding, analytics, and large-scale operational platforms.
At Careem, I enhanced Apollo, an internal dispute resolution platform, delivering APIs and real-time contextual data for support agents. I integrated Zendesk and Genesys and implemented Flowable-driven workflows to standardize resolution processes across ride, food, bike, and logistics services.
At POS Malaysia, I maintain enterprise integration services and backend capabilities for vehicle tax and insurance renewal. I also led centralized OAuth2 identity work with WSO2, Keycloak integration, and a Vue.js and Go registration portal, while helping migrate Apache Camel services from Java to Go.
Earlier, I improved Hijra Bank selfie-verification accuracy from 80% to 85%, introduced Kafka, Docker, and Kubernetes at PT Eluon Indonesia, and built factory systems that replaced manual and Excel-based workflows. I work hands-on across Java, Kotlin, Go, Spring Boot, cloud platforms, distributed systems, and modern frontend stacks.
