Could you build this?
Partial A basic UI with OAuth flows is easy to vibe-code, but robust multi-way calendar sync requires handling complex recurring event edge cases, webhook race conditions, and CalDAV protocol intricacies.
What it would actually take: A production implementation requires a queue-based background worker architecture (e.g., Temporal, BullMQ, Redis) handling webhooks and incremental sync tokens across Google Calendar, Microsoft Graph, and CalDAV. The difficult parts include iCalendar RRULE parsing/expansion, idempotent event deduplication, split-brain conflict resolution, and handling strict rate limits. Specialized domain experience with calendar sync RFCs and third-party calendar APIs is required.

Same idea, different domain
Nobody's really built a workflow automation tool for Real estate yet.
