💻 10+ Years of Mobile App Development Experience ⭐ Top Rated Talent with Consistent 5-Star Client Reviews 🚀 Expert in Building Native iOS Apps from Idea to App Store Hi, I'm Sandip Singh, a Senior iOS Developer with over 10 years of experience building high-quality mobile applications for startups, businesses, and growing companies. I specialize in native iOS development using Swift and SwiftUI, helping clients transform ideas into polished, scalable, and App Store-ready products. Whether you're launching a new MVP, modernizing an existing application, or integrating AI-powered features, I focus on delivering clean architecture, excellent performance, and a great user experience. Over the years, I've worked with startups, agencies, and established businesses across healthcare, fintech, education, transportation, real estate, and B2B/B2C products. I've also contributed to production applications such as MagicPlan and other commercial mobile products used by real customers. ### What I can help you build ✅ Native iOS applications with Swift & SwiftUI ✅ AI-powered features using OpenAI, LLMs, chatbots, assistants, and workflow automation ✅ Firebase integration (Authentication, Firestore, Analytics, Cloud Messaging, Crashlytics) ✅ User authentication (Apple Sign-In, Google Sign-In, Email & Social Login) ✅ Subscription-based applications with In-App Purchases and Stripe integration ✅ REST APIs, GraphQL, WebSockets, and third-party SDK integrations ✅ Push notifications, deep linking, analytics, and event tracking ✅ Performance optimization and app architecture ✅ Bug fixing, feature development, code reviews, and long-term maintenance ✅ App Store deployment, TestFlight distribution, and release management ### Apple Technologies • Swift • SwiftUI • UIKit • Objective-C • Core Data • Core Location • MapKit • AVFoundation • Vision Framework • ARKit • RoomPlan ### AI & Modern Integrations • OpenAI APIs • LLM Integration • AI Chat • AI Automation • Prompt Engineering • Voice AI Features • Firebase AI Integrations ### Backend & Cloud • Firebase • AWS • Google Cloud Platform • REST APIs • GraphQL • MySQL • SQLite ### Cross-Platform Experience While my primary expertise is native iOS development, I also have experience working with: • Flutter • React Native • Kotlin • Java This allows me to collaborate effectively with cross-platform teams when projects require it. ### Development Approach I believe successful mobile applications are built through thoughtful planning, clean architecture, efficient communication, and attention to detail—not just writing code. When working together, you can expect: • Clean, maintainable, and scalable code • Clear communication and regular progress updates • Reliable timelines and professional collaboration • Performance-focused development • Long-term support after launch My goal is to build applications that are stable, scalable, and enjoyable for users while helping clients achieve their business goals.
