Senior N8n Automation Developer – Google Calendar & Firebase Integration

We are seeking an experienced automation developer for a test project with potential for long-term collaboration. The project involves building a highly optimized and reliable integration between Google Calendar and Google Firebase using n8n. When a reservation or task is created in Google Calendar, the system must automatically create a corresponding record in Firebase, and when a reservation is canceled, the related record must be removed or updated accordingly. After the scheduled time has passed, the reservation status should automatically change to “Completed.” The solution must be scalable, production-ready, and include strong exception handling for issues such as concurrent bookings, duplicate executions, race conditions, API failures, and synchronization conflicts. We are looking for someone with strong experience in n8n workflows, Google APIs, Firebase architecture, and automation optimization who can deliver clean, maintainable, and efficient workflows with proper logging, retry logic, and error management. Candidates should also provide documentation, architecture explanations, and examples of similar automation projects they have completed.
