One publish, six platforms
My role
Part of the Cognilium team build. The mirror orchestrator, the syndication targets, and the platform inventory behind it are my work.
The problem
Writing is the easy half. The reach comes from distribution, but manually reposting every article to a dozen platforms is the kind of chore that quietly never gets done.
What I did
- Built a mirror orchestrator: every Sanity publish fires one HMAC-signed webhook that syndicates the post to Dev.to, Hashnode, Flipboard, Bluesky, a LinkedIn newsletter, and a Resend broadcast.
- Made it idempotent per slug, so re-publishing or editing a post updates the mirrors instead of posting a second copy across six platforms.
- Built manual and selective fire modes (--only, --dry-run) plus a status tool that shows the mirror state of every post.
- Maintained a single-source-of-truth inventory of 130+ platforms with status tracking and an add-a-platform runbook, so the channel list is a system, not tribal knowledge.
The result
Distribution that runs itself: publish once and the post is optimized, indexed, and mirrored across the web automatically, with no duplicate posts.
The judgment call: what the AI couldn't do
I caught the syndication firing duplicate posts on re-publish before it shipped, and made the webhook idempotent per slug. Speed is worthless if it publishes the same article five times across six platforms.
