Overview
From artwork to post, on time.
A panel and scheduler that renders the artwork and publishes the ads for my deals brand on Facebook and Instagram.
Product definition and AI-assisted development, connecting requirements, implementation and review.
Posting automatically to Facebook since 31 Oct 2026; Instagram was connected on 1 Nov 2026. One post every 6 hours per network, 93 tests passing, and only confirmed post IDs count as published.
The problem
Promoting communities every day on two networks, with copy that does not repeat, the right links for each network and no one having to remember to post.
The solution
A Next.js panel with Prisma and Zod validation; a worker that renders artwork and vertical ads with Sharp and FFmpeg (1080×1920, QR code on the last frame); a scheduler that publishes through Meta's official Graph API. Captions rotate across 30 openings for 10 artworks.

Technologies
Technical challenges
Meta OAuth. Authorisation came back with an empty list of Pages. Instead of asking for broader permissions, I logged only steps and counts (no tokens) and found the real cause: the account used managed no Page.
Real screenshots
Real output produced by the system.
Lessons learned
Simulation first, real posts later. The app ran in simulated mode for weeks before its first public post, and any uncertain send stays out of the count until it is confirmed.
