Building iOS apps that perform

I'm a Senior iOS Developer with 7+ years of IT experience and 6 years of specialised expertise in iOS application development (iOS 13–17). I build performant, clean-architecture apps that users love.

My expertise spans Swift, Objective-C, SwiftUI, UIKit, and Combine, with a deep focus on MVVM patterns, performance profiling, and scalable code that stands the test of time.

I've shipped apps with 100K+ collective downloads and maintained 4.6+ star ratings on the App Store — from fintech platforms handling international money transfers, to high-traffic e-commerce apps and community platforms.

Experienced integrating Firebase, WebEngage, Branch SDK, Lottie, and payment gateways, and managing CI/CD pipelines via GitHub Actions. I'm comfortable owning the full release lifecycle end-to-end.
