Own end-to-end delivery of production Flutter features — from scoping and architecture through to release — serving thousands of daily active users across iOS and Android. Built reusable widget libraries and modular component systems that reduced feature development time by ~30%, enabling faster product iteration across multiple squads. Drove performance optimisation initiatives (widget rebuild profiling, memory management, frame-rate analysis) to maintain smooth 60fps UI rendering at scale. Integrated RESTful APIs with PHP back-end services, reducing data-sync latency and improving perceived app responsiveness for end users. Implemented automated UI test suites using Appium to validate critical user flows across iOS and Android, improving release confidence and reducing regression rate. Shipped features iteratively in Agile/Scrum sprints, collaborating with backend, design, and QA teams — consistently meeting sprint commitments across concurrent product lines.
