Calendar synchronization tool for syncing events across multiple Google calendars with configurable rules and multi-user support. While there are products in the marketplace that do this, we are builders and felt this integration as a Google Cloud project would lead us towards further innovations. Supports multi-calendar sync with customizable rule configurations, enabling seamless event coordination across teams. Deployed on IONOS Cloud using Infrastructure as Code with Terraform, containerized with Docker, and automated through GitHub Actions for continuous delivery.
