Sheet 03 — Case Study
Creator platform
LiveLinkPostcard
A link-in-bio hub for creators: one page for links, short lessons, podcast episodes and connected platforms.
Automatic content sync coming soon.
The problem
Creators spread their work across course platforms, communities, stores and social channels, and a plain list of links can't show lessons or new episodes in one place.
Who it is for: Creators who sell courses, communities and products across several platforms.
What we built
- A public page for each creator, with links grouped by category
- Lessons published right on the page, with an optional code sample or video link
- Podcast episodes synced from an RSS feed
- YouTube, TikTok, Patreon and Gumroad account connections
- Pro billing through Stripe checkout, webhook and customer portal
Engineering quality
- Each platform was checked for a real public API before being offered; the rest are honest outbound links
- Email-confirmed sign-in, plus Google, GitHub and LinkedIn
- Connected accounts' tokens encrypted at rest with AES-256-GCM
- Vercel BotID, automated axe accessibility tests to WCAG 2.2 AA, secret scanning and static analysis
