   • Implemented an automated customer notification system (invoice statuses and payment confirmations) to reduce manual follow-up.
   • Built an integration with Rev.io and implemented document storage on Microsoft Azure to extend the platform’s billing and storage capabilities.
   • Maintained and operated a fleet of 40+ cloud-native .NET and Angular microservices on GCP, containerized and deployed to Kubernetes (GKE) with Helm and Istio through a GitOps CI/CD pipeline, within an Nx monorepo applying TDD.
