Led the development of scalable iOS features in SwiftUI with Combine, from technical discovery to test coverage, accessibility, tracking, and A/B rollout. Refactored legacy core selection logic into a modular, protocol-oriented, Combine-based component, enabling cleaner architecture and scalable feature expansion. Designed and implemented Auto Save as a protocol-oriented, testable Swift module using Combine, contributing to measurable revenue growth. Delivered multi-quantity add-ons, Meal Completion, and Cart Revamp using SwiftUI and Combine, boosting engagement and contributing to AOV uplift. Improved operational efficiency by configuring Firebase traces, Grafana alerts, and reducing QA workload via UI automation, cutting manual tests from 32 to 11 and saving ~0.5 developer days.

Senior iOS Engineer delivering multiple scalable features in SwiftUI with Combine, covering technical discovery, test coverage, accessibility, tracking, and A/B rollout. Refactored legacy core selection logic into a modular, protocol-oriented Combine-based component to enable cleaner architecture and scalable feature expansion. Designed and implemented Auto Save (protocol-oriented Swift module using Combine), driving ~1.4% increase in average order value (AOV) and revenue. Delivered multi-quantity add-ons, Meal Completion, and Cart revamping using SwiftUI and Combine; improved engagement. Reduced QA workload by introducing UI testing automation and performance improvements.

Led high-impact initiatives such as AutoSave, CartRevamp, MealSelection, and Subscription Add-ons using SwiftUI and concurrency, resulting in a 1.4% AOV increase in the Cart, translating to millions in revenue. Refactored legacy core selection logic to reduce conflicts and improve quality, covered missed unit tests, and automated manual tests significantly reducing the number from 32 to 11. Managed and mitigated critical cart domain issues and wrote post-mortems. Enhanced operational excellence by integrating Firebase performance traces and configuring metrics alerts on Grafana. Fostered a strong code review culture promoting continuous improvement among developers.
