Technical articles about calendar APIs, OAuth security, free/busy merging, and the engineering behind reliable multi-calendar conflict detection.
About
Cal Clear Engineering is the byline for our technical articles — posts about Google Calendar's freeBusy API, OAuth token lifecycle, calendar caching anti-patterns, anti-spam architectures, and the real-time systems that make a booking page usable.
We believe that if a scheduling tool claims it checks multiple calendars reliably, it should be able to explain in plain English exactly how. Our engineering posts are that explanation for Cal Clear — and a critique of the shortcuts other tools take.
If you're a developer curious about how we handle OAuth refresh, time-zone arithmetic, availability caching, or spam detection, these posts are for you.
