What I'm looking for

I’m looking to build production-ready iOS apps in Swift/SwiftUI using MVVM & Clean Architecture, owning secure real-time API features and measurable performance improvements—collaborating closely with backend and QA to ship reliably.

I’m an iOS Developer with 3+ years of experience building scalable, high-performance mobile applications using Swift, SwiftUI, and UIKit. I bring strong expertise in MVVM and Clean Architecture, API integration, CoreData, and real-time data handling, with a track record of delivering production-ready apps across pharma and sales domains.

In my recent role, I developed SaaS-based iOS applications, improved app performance by ~30%, reduced API latency, and implemented secure handling of sensitive data through encrypted API communication and authentication. I also reduced crash rate by ~25% through debugging and memory management, and I enjoy collaborating with backend and QA to ship stable releases. I’m energized by building secure, responsive, real-time user experiences and turning complex data workflows into reliable products.
