At KuickTech, I developed social features for LikePost, including friend connections, profiles, post sharing, collections, and an activity feed. I also improved feed loading time by 30% through pagination, caching, and optimized API requests.

At M Three Health, I implemented real-time heart rate zone monitoring for Apple Watch workouts and integrated HealthKit to read and write workout data. I also implemented synchronization between the iPhone and Apple Watch apps.

At Zeythech, I created custom UIKit elements, implemented unit and UI tests, and automated testing and build distribution through CI/CD. My iOS work includes Swift, SwiftUI, GraphQL, Apollo, and maintainable architectures.
