• Make independent team-level architecture decisions and communicate tradeoffs across usability, security, performance, reliability, and delivery speed.

• Build resilient transactional experiences with deliberate validation, error handling, recovery paths, testing, and observability.

• Coordinate dependencies with backend, platform, security, compliance, product, and design partners to move initiatives from ambiguity to production.

• Mentor engineers and raise the team's standards for mobile architecture, code quality, operational ownership, and customer-centered engineering.
