An energy platform that gave internal teams live pricing information and operational metrics to support daily decisions. Its core features included real-time dashboard updates, background data processing and integrations between backend services. I developed Node.js services using Redis, Firebase Pub/Sub and WebSockets, and contributed to Azure deployment pipelines, identity management, monitoring and Terraform infrastructure. My responsibilities also included production troubleshooting, UAT and release support, taking changes from implementation through verification and deployment.
