Background

About Arvind Dangar Ahir

I am a Senior Software Engineer with 9 years of experience in software development and engineering, specializing in iOS mobile application development and Java Spring Boot backend systems. I bring a product-driven mindset and strong technical leadership, with expertise spanning the full product lifecycle from concept to deployment. My core focus lies in building robust, scalable, and secure iOS applications for iPhone, iPad, and Apple Watch. I have hands-on experience in designing advanced UI/UX, managing complete app lifecycles, and integrating complex backend services with cloud and AI capabilities. In the iOS domain, I have developed applications with In-App Purchases, Wallet Pass integration, WatchOS support, SwiftUI-based interfaces, MVVM architecture, and advanced multithreading. I have built universal apps using size classes and auto-layout, and implemented secure app architectures using Keychain, Face ID/Touch ID, jailbreak detection, SSL pinning, and AES encryption for API communications. I’ve successfully led and managed entire development cycles for iOS apps — from assigning tasks and coaching teams to handling Apple Developer account management, certificate and provisioning profile generation, and App Store submission. I have extensive experience working with SQLite, RESTful APIs, AFNetworking, Alamofire, URLSession Codable, JSON parsing, and third-party libraries via CocoaPods. I’ve also integrated AWS S3 for secure file handling, iBeacons, Core Location, Core Data, Google Maps, and Firebase Chat. On the backend, I design scalable REST APIs using Java Spring Boot and integrate Azure AI services to enable intelligent and personalized app experiences. Key Highlights: • 9 years of software engineering experience (iOS & Java Spring Boot) • Expert in Swift, SwiftUI, Objective-C, In-App Purchases, Wallet Passes, WatchOS • Secure iOS development (Keychain, Face ID/Touch ID, SSL pinning, anti-debugging) • RESTful API design, Spring Boot backend, Azure AI integration • End-to-end mobile product development and deployment • Universal apps, multithreading, MVVM, advanced UI/UX • Team leadership, coaching, and project management I am passionate about crafting innovative and secure mobile experiences, constantly learning new technologies, and contributing to products that make a real impact.
