I am a Senior iOS Developer, I architect and deliver production grade iOS apps with 4+ years of focused experience in Apple’s ecosystem, I lead the development of apps from zero to App Store launch, rebuild unstable codebases and implement complex features spanning subscriptions, AI integrations, real-time systems and advanced native capabilities. 𝗖𝗼𝗿𝗲 𝗘𝗻𝗴𝗶𝗻𝗲𝗲𝗿𝗶𝗻𝗴 𝗘𝘅𝗽𝗲𝗿𝘁𝗶𝘀𝗲: • Native iOS development with Swift, SwiftUI, UIKit, and Objective-C. • Architecture design: MVVM, Clean Architecture, modular systems, scalable state management. • Concurrency and performance optimization using async/await, GCD and efficient threading models. • Building complex UI systems with smooth animations, adaptive layouts, and pixel perfect implementation. • Robust networking layers, API integrations, caching strategies, and offline resilience. 𝗜 𝗵𝗮𝘃𝗲 𝘀𝘂𝗰𝗰𝗲𝘀𝘀𝗳𝘂𝗹𝗹𝘆 𝗱𝗲𝗹𝗶𝘃𝗲𝗿𝗲𝗱 𝗮𝗽𝗽𝗹𝗶𝗰𝗮𝘁𝗶𝗼𝗻𝘀 𝗶𝗻𝗰𝗹𝘂𝗱𝗶𝗻𝗴: • AI-powered apps with complex backend integrations • Subscription-based platforms with reliable monetization flows • Real-time and media-heavy applications • MVPs that evolved into production products • Complete rebuilds of unstable or poorly structured apps 𝗛𝗲𝗿𝗲'𝘀 𝘁𝗵𝗲 𝗿𝗼𝗮𝗱𝗺𝗮𝗽 𝗳𝗼𝗿 𝗯𝗿𝗶𝗻𝗴𝗶𝗻𝗴 𝘆𝗼𝘂𝗿 𝗽𝗿𝗼𝗷𝗲𝗰𝘁 𝘁𝗼 𝗹𝗶𝗳𝗲: • Grasp project requirements thoroughly • Design the user interface of the application • Implement essential functionalities • Comprehensive testing • Submitting your app for launch When you collaborate with me, you can expect nothing less than meticulous attention to detail, a deep understanding of project requirements and a relentless drive for excellence.

Most mobile developers write code. I ship products. With 10+ years of native iOS engineering across 10+ live apps — from zero-to-one startups to mature platforms with real users — I know the difference between code that looks good in a demo and code that holds up at 2am when something breaks in production. My core is iOS: Swift, SwiftUI, UIKit, Objective-C. I've built everything from real-time multiplayer games to complex data-heavy apps to AI-powered mobile tools. If it runs on iPhone, I've probably built something like it. Beyond native iOS, I work with Flutter and React Native when cross-platform makes more sense for the project — I'm not religious about the stack, I'm focused on the right outcome for your product. What founders and product teams tell me they value: I don't disappear into a sprint and surface two weeks later with questions. I flag problems early, communicate clearly, and treat your product like it matters — because it does. Good fit if you're: — A startup that needs a reliable senior engineer to own the mobile layer end to end — An ongoing product that needs someone who can jump in, understand the codebase fast, and deliver — A team that's been burned by developers who overpromised and underdelivered 100% Job Success. Top Rated. Let's talk.
