Hello there! I Have 7+ years of experience as mobile application developer. I've created several projects of different natures for professional folks like yourself. Have a pretty good grip on Swift, Swift UI, and regarding ReactNative I have worked around 1.5 years on that. Major iOS framework that I work upon on daily basis: AuthenticationServices BackgroundTasks UIKit MapKit CoreData WebKit UserNotifications Beyond my technical skills, I have solid management and communication skills which I’ve groomed over the years while studying at university and working in both large and small companies. I’ve worked at some of Pakistan’s top software companies with clients worldwide – in several leadership roles. I’ve had the chance to work with clients from across the world, both through Upwork and at the companies I’ve worked at, which has given me extensive exposure in ensuring I meet timelines and maintain communication, irrespective of time zones. I am looking forward to hearing from you!

🫵 Need a senior iOS & macOS engineer who can take your product from idea to App Store – and keep it fast, stable, and maintainable as it grows? 🏆 Key Highlights • 7+ years of deep, hands-on experience building and scaling complex iOS & macOS applications in real production environments. • Senior-level architecture & coding: MVVM, VIPER, Clean Architecture, modular design, dependency injection, SOLID – I design codebases that stay clean and extensible for years, not months. • Deep focus on quality and performance: crash reduction, memory/CPU optimization, complex UI and heavy lists, smooth animations, and profiling with Instruments. • Solid experience with complex integrations: secure payments, authentication/authorization, offline modes, background sync, advanced navigation and routing, analytics, and monitoring. 📱 What I Do Best • End-to-end product delivery • Strong, scalable architectures • Performance & stability engineering • Legacy rescue & modernization ⭐ What Makes Me Different • Production first, not demos – I work with real users, real traffic, and real constraints, focusing on reliability, performance, and maintainability instead of “just working on my machine.” • Engineering with standards – systematic crash reduction, profiling with Instruments, careful Core Data / storage optimization, and attention to edge cases and failure modes. • Architecture as a long-term asset – I design modular, testable systems that keep your future changes safer, faster, and cheaper, regardless of team size. 💼 Experience Areas • Fintech & banking • Payments & loyalty platforms • Marketplaces • Cloud storage • Maps & geolocation • Health & wellness • Media-heavy applications • macOS productivity tools 🔄 How I Work I start by clarifying goals, constraints, and edge cases. Then I propose a clear implementation plan with milestones, risks, and trade-offs upfront. I deliver in short, transparent iterations with production-ready standards, clean code, and predictable results. Comfortable working async with distributed teams or integrating smoothly into existing workflows. ☑️ Core Skills & Technologies 1) Apple Platforms • iOS, macOS • Swift, SwiftUI, UIKit, AppKit • Auto Layout, XIB-based interfaces 2) Architecture • MVVM, Clean Architecture, VIPER, Coordinator • Dependency Injection, modular design • SOLID principles 3) Concurrency & Performance • async/await, Combine, RxSwift, GCD, OperationQueue • Instruments profiling (time, memory, CPU, allocations) • Performance tuning, memory & CPU optimization 4) Data & Offline • Core Data, Realm • Caching strategies, background sync, conflict resolution • Large media handling (photo / video) 5) Networking • REST APIs, OpenAPI / Swagger-style contracts • URLSession, Alamofire • Pagination, retry / backoff strategies, response caching 6) Security • Keychain, secure token storage • Session management, OAuth / JWT-based auth flows • Banking-grade client security practices 7) Analytics & Monitoring • Firebase (Auth, Firestore, Storage, Analytics) • Sentry, Crashlytics • Production debugging & observability 8) CI/CD & Release • Fastlane, TestFlight, App Store Connect workflows • Code signing & provisioning • Git-based CI/CD pipelines 9) Quality & Maintainability • XCTest (unit & UI tests) • Code reviews, refactoring • SwiftLint, SwiftFormat, clean coding standards 10) Advanced Topics • ML & Computer Vision integrations • ARKit basics • Algorithmic problem solving • Maps, routing logic, geospatial features 📩 Ready to move fast without sacrificing quality? Invite me to your job on Upwork - I’ll help you turn complex requirements into a stable, scalable Apple-platform product. Last updated: January 2026

Got an idea you want to turn into a real product? Let's talk. I help non-technical founders and business owners build AI-powered MVPs, SaaS platforms and Mobile Apps (iOS & Android) from first concept to a live, working product. Based in Dubai, UAE, I work with clients across the US, UK and the Middle East who need someone they can trust to own the technical side of their project, so they can focus on their business. What makes me different: I'm not just a developer who writes code and disappears. I ask the right questions, give honest feedback on your idea and stay with you through the full journey from scoping to launch. ✅ WHAT I DELIVER ✔️ AI-Powered Web Apps & SaaS Platforms: Multi-tenant SaaS products with AI automation, smart dashboards, role-based access, subscription billing and third-party integrations. I integrate OpenAI and LLM APIs to give your product intelligent features, automated data extraction, AI-driven notifications, smart document processing and decision-support tools. ✔️ MVP Development: Got an idea? I help you scope it down to the essentials, build the first working version fast, and get it in front of real users. No bloated features. No wasted budget. Just a lean product that validates your idea. ✔️ Mobile Apps (iOS & Android): Cross-platform mobile apps built with Flutter and React Native from ride-hailing platforms to B2B tools and on-demand services. Clean UI, real-time features, and full App Store / Play Store deployment included. ✔️ Web Application Development: Full-stack web apps built on React, Node.js, Laravel, and Python/Django. Scalable from day one so you don't need a costly rewrite six months after launch. ✔️ AI Feature Integration: Already have a product and want to make it smarter? I add AI capabilities to existing platforms, document automation, intelligent alerts, chatbots, workflow automation and LLM-powered features using OpenAI API. ✔️ Dashboards & Admin Panels: Real-time analytics dashboards, role-based admin tools and reporting panels that turn raw data into decisions your team can act on. 🛠️ TECH STACK Mobile: Flutter, React Native, iOS, Android Frontend: React.js, Next.js, Tailwind CSS Backend: Node.js, Laravel, Python, Django, REST APIs AI: OpenAI API, LLM Integration, AI Document Processing Database & Cloud: PostgreSQL, MySQL, MongoDB, Firebase, AWS Payments: Stripe, PayPal, In-App Subscriptions HOW I WORK: I respond fast, communicate in plain English and I'll always tell you the truth about scope, timeline, and budget before it becomes a problem, not after. I take on a limited number of projects at a time so every client gets proper attention, not just a ticket in a queue. If something changes during the build, you'll know immediately. No surprises at the finish line. I WORK BEST WITH: - Non-technical founders building their first SaaS or mobile product. - Businesses that need an AI layer added to an existing platform. - Startups that want one reliable person to own the full technical delivery. - Companies with a legacy or broken app that needs a proper rebuild. - Entrepreneurs in the UAE, US or UK who want a partner not just a contractor. LET'S START WITH A CONVERSATION: Message me with a short description of what you're building. I'll get back to you within a few hours with honest thoughts on your idea, a rough scope and whether I'm the right fit for it. No pressure. No pitch. Just a real conversation. KEYWORDS: MVP Development, Startup MVP, AI-Powered SaaS, Full Stack Development, Cross-Platform App Development, iOS & Android, Flutter, React Native, App Store & Play Store Deployment, Real-Time Features, Push Notifications Web: React.js, Next.js, Node.js, Laravel, Python, Django, REST APIs, API Integration, Multi-Tenant SaaS, Stripe Integration AI: ChatGPT Integration, OpenAI API, LLM Integration, AI Automation, AI Chatbot Development, AI Document Processing, Generative AI, AI Workflow Automation Database & Cloud: PostgreSQL, MySQL, MongoDB, Firebase, AWS, Docker UI/UX: Responsive Design, Clean UI, Admin Dashboards, Real-Time Analytics Working style: Agile, Sprint-based delivery, Clear communication, UAE-based
