MOBILE ↔ BACKEND OWNERSHIP

A strong mobile engineer designs around API contracts, authentication, error mapping, realtime behavior, persistence boundaries and server-authoritative business rules. These are demonstrated as engineering judgment—not fabricated employer history.

ENGINEERING JUDGMENT

Production situations worth discussing

Token refresh race condition

Coordinate a single refresh and safely replay eligible queued requests.

Offline sync and conflicts

Separate local intent, reconciliation and domain-specific conflict policy.

Old apps vs new backend

Evolve APIs around real mobile adoption and store-release latency.

Deep links and cold start

Resolve bootstrap, auth and pending navigation through one state owner.

Payment idempotency

Treat server reconciliation—not a button response—as payment truth.
