iOS companion app
Nexus
Native SwiftUI companion to Nexus Study, hitting the same Supabase backend through dedicated mobile-facing Edge Functions instead of a second copy of the business logic.
A strong case study should explain the workflow, the constraints, and the product judgment behind the interface.
Primary metric
Shipping alongside the web app
Product maturity
3/3 shipped signals
Role
Native app architecture, backend integration, and decoder/reliability hardening.
Challenge
A native client and a web-first backend drift apart — mismatched field casing, date formats, and silent fixture fallbacks that mask a real API failure as an empty state.
Approach
Hardened the decoding layer against schema drift, removed silent-fallback paths so a broken response fails loudly instead of quietly showing fake data, and migrated auth token storage to the Keychain.
Impact
Students get the same study loop natively, and the app now fails honestly instead of hiding backend problems behind demo content.

Ships the same study loop natively, hardened against the schema drift that a native client and a web-first backend inevitably develop.
Highlights
- Shared Supabase backend
- Schema-drift-hardened decoders
- Keychain-backed auth
