MOBILE PRODUCT TEAMS / IOS & ANDROID
Mobile products with reliable backend contracts.
For teams building or repairing native apps where the problem crosses device state, identity, API behavior and release ownership.
SYSTEM RISK / REAL FAILURE CONDITIONS
The boundary is the problem.
An app can pass a happy-path test and still fail during token refresh, reconnection, account recovery or an interrupted upload. The backend needs to enforce permission regardless of client integrity or cached state.
TRUST FLOW / ILLUSTRATIVE ARCHITECTURE
- 01SwiftUI / Kotlin screens and device state
- 02Signed requests, identity and offline queueing
- 03API object authorization and server-owned records
- 04Observability, release gating and rollback
Reference architecture / representative request flow.
NEGATIVE-PATH VERIFICATION
What we'd test
- Revoked session during an in-flight operation
- Cross-account request with a legitimate app instance
- Backgrounded device and duplicate retry
- Rollback and version skew during staged deployment
EXPECTED PROJECT OUTPUTS
What the team receives
- Defined API and state contracts
- Implemented client/server changes where scoped
- Negative-path regression tests
- Release checklist and handoff
Scope, access, deliverables and acceptance conditions are agreed before work begins.
