About

Senior iOS Engineer with 8+ years of experience building scalable, high-performance mobile applications using Swift, SwiftUI, and UIKit. I focus on designing maintainable mobile architectures and delivering reliable production systems used by enterprise and consumer applications. My experience includes Clean Architecture, MVVM, SOLID principles, dependency injection, and Core Data concurrency. I have led large feature implementations, reduced critical crash rates, and improved CI/CD pipelines and App Store release workflows for production iOS applications. Beyond mobile engineering, I also served as a Team Lead (Calibrator) on large-scale LLM evaluation initiatives (RLHF & InverseIF), managing distributed reviewer teams and improving structured model alignment processes. Core strengths • Swift, SwiftUI, UIKit • Mobile Architecture, Clean Architecture, MVVM • Core Data, Concurrency, Combine • CI/CD (Fastlane, GitHub Actions) • Agile/Scrum, Code Reviews • App Store deployment lifecycle • AI / LLM evaluation workflows I am currently based in India and open to relocating to Berlin, Amsterdam, and other EU tech hubs for Senior iOS Engineer roles.
