Role Purpose :

Own and lead the mobile application as a production-grade, offline-first system by ensuring correctness, data integrity, reliability, and performance across low-connectivity environments and low-end Android devices.

Key Roles & Responsibilities :

- Design and implement offline-first mobile architecture with robust local persistence and sync mechanisms

- Own local data models, schema versioning, migrations, and backward compatibility

- Implement reliable sync logic including retries, backoff, conflict resolution, and recovery

- Ensure idempotent data writes and safe replay under partial failure scenarios

- Manage app lifecycle events including backgrounding, restarts, long offline windows, and app kills

- Own crash handling, ANR prevention, memory usage, and battery performance

- Diagnose and resolve production issues using telemetry, logs, and profiling tools

- Define and maintain mobile-to-backend API contracts and schema evolution

- Ensure graceful degradation during network or dependency failures

- Own release management, upgrade paths, and zero data loss across app versions

- Establish observability standards for sync health, failures, and system reliability

- Define and enforce quality thresholds for production releases

- Collaborate closely with backend, data, and product teams to deliver reliable systems

Key Result Areas (KRAs) :

- Stability and reliability of mobile applications in low-connectivity environments

- Data integrity and zero data loss across sync cycles and app upgrades

- Sync success rates and recovery from partial or long-duration failures

- Reduction in crashes, ANRs, and production-only issues

- Performance efficiency on low-end devices including memory and battery usage
