🧑‍💻 About Me

I'm a Senior Software Developer and API Integration Specialist based in Jakarta, Indonesia. With deep experience spanning Android, iOS, and full-stack web development, I specialize in building enterprise-grade systems — from mobile applications to cloud-native microservices. Currently working with Bank BNI on API integration, I bring a product-minded approach to every line of code, whether it's a payment gateway, a POS system, or a Kubernetes-deployed mock API.

I believe in clean architecture, disciplined engineering, and shipping things that actually work.
