The client needed more than a brochure: a professional brand site with authentication and OAuth so the right users can access protected areas securely.
Interface sketch
The problem
01Public marketing pages and private access often live in separate systems. The client needed both: a credible public face and authenticated entry without fracturing the brand.
Approach
02- Next.js project base from Figma with responsive UI and motion
- Authentication + OAuth for secure access
- Content/SEO structure for marketing campaigns
- Collaboration loops with marketing for content velocity
Key decisions
03- Treat auth as part of the product UX, not a bolted-on portal
- Keep public and private surfaces visually consistent
- Prefer clear error/empty states over silent auth failures
