Derwin O.

I am a Backend Engineer at Bank Rakyat Indonesia (BRI), currently working on the core infrastructure for BRImo (Mobile Banking) and EDC (Electronic Data Capture) systems. What I bring to your project: - Scale & Reliability: I architect high-concurrency microservices using Go and NestJS that survive heavy production loads. - Event-Driven Architecture: I implement Apache Kafka and RabbitMQ to ensure complex data flows are processed asynchronously and without data loss. - Infrastructure Ownership: Unlike many backend devs, I handle my own deployments. I am proficient with Kubernetes (K3s/OpenShift), Docker, and AWS. - Protocol Expertise: Experience with gRPC for low-latency internal communication and ISO 8583 for payment processing. I have been shipping production code for major financial institutions since 2024.
