What I'm looking for

I’m looking for an iOS role where I can own app delivery end-to-end—building Swift/MVVM features, integrating APIs, and improving stability and UX through testing and performance-focused engineering.

I’m an iOS Developer with 5+ years of experience designing, developing, and managing apps across the full SDLC, with a strong focus on third-party API integration, requirements analysis, effort estimation, and technical design.

At iSemi Technology (An Infosys Company), I work as a Senior Software Engineer on Apple’s internal macOS & iOS application (Willow/SafeView). I contribute to an MVVM-based hybrid stack (SwiftUI + AppKit), using Swift Structured Concurrency (async/await) and XPC, and I’ve delivered fixes across window management, Picture-in-Picture behaviors, screenshot saving edge cases, and navigation issues across OS flows and deployment environments.

Previously, at Datamatics Global Services, I developed the Mahindra Imaxx iOS app for Bosch, integrating RESTful APIs for real-time telemetry, live tracking (individual and fleet), payment gateway integration (CC Avenue), and DigiLocker for document access. I’ve also strengthened reliability through unit testing (XCTest), QA-aligned UI validation, and performance-minded UI/UX work including multi-language localization.
