From a blog post to LinkedIn — in one button.

Every post on simeonherbert.com deserved a LinkedIn version — but doing it by hand meant copy, paste, reformat, fight with line breaks, pick an image, and then inevitably ship the post a week late. The friction was killing the cadence.

The blog admin — built in Lovable, backed by Supabase — has a character counter built in that tracks against LinkedIn's 3,000 character limit as you write. When you're ready, you hit Schedule via Buffer and it calls a Supabase Edge Function that hands the post off to Buffer, which queues it for LinkedIn at the right time. If the post is too long for LinkedIn, the editor prompts for a shorter version and appends the canonical link automatically.

One source of truth. The blog stays canonical. LinkedIn becomes the megaphone.

The short-version prompt is currently manual — I want an AI step that drafts the LinkedIn teaser for me given the full post, so I'm editing rather than writing from scratch. The failure path when Buffer throttles also needs a friendlier retry than a toast notification that disappears.

Posting cadence held for a full quarter without a Sunday-night panic. The LinkedIn versions out-perform the ones I used to write manually — probably because they actually ship.
