Led a team of 12 iOS engineers across technical and people management, making architecture decisions, setting code standards, hiring, and supporting career growth. Owned performance reviews, onboarding, and 1-on-1s. Ran the end-to-end iOS hiring pipeline with technical interviews and offer decisions. Planned iOS roadmap with product, set team priorities, and drove delivery processes (sprints, code review, release cycles) while reporting to leadership. Completed migration from a monolithic architecture to a modular system of 100+ frameworks, improving scalability and team velocity. Reduced time-to-market by 25% through modular architecture and CI/CD pipeline improvements. Introduced AI-assisted development workflows including test-first generation of unit/integration tests, structured debugging, and validation pipelines to verify AI-generated code. Increased automated test coverage from 5% to 70%, reducing regression risk in a large production codebase.
