The challenge
A portfolio app should prove judgment, not just implementation.
Many marketplace demos depend entirely on production secrets or a warm database. That creates a fragile first impression: the UI may compile, but the product story disappears when infrastructure is unavailable.
The solution keeps the production path intact while adding a typed, read-only catalog fallback. Search, filters, cards, and details share the same domain shape, so the public demo stays useful without hiding the real MongoDB and authentication architecture.
System design
Clear boundaries, graceful degradation.
Identity & permissions
Google OAuth with protected owner workflows and role-aware administration.
Data layer
Typed Mongoose models, validation at the boundary, and a resilient read-only demo fallback.
Delivery
Next.js App Router, dynamic rendering where it matters, health endpoint, and deployment-ready metadata.
Key decisions
What I optimized for.
- 01
Evaluator-first resilience
Public read paths fall back to curated data; authenticated writes still require the real persistence layer.
- 02
URLs as product state
Search filters use query parameters, keeping results shareable and server-renderable.
- 03
Boundary validation
The schema and API normalization own data constraints instead of relying only on form controls.
- 04
Progressive capability
The core browsing experience works immediately; identity unlocks owner and admin workflows.
