I build the mobile apps that can't fail: official Amazon Location Android SDKs, ONWARD Medical's ARC-EX (a first-of-its-kind FDA-cleared spinal cord stimulator), and Fibe, a fintech lending app with 10M+ downloads. I'm usually hired when a project involves more than standard app screens: real-time systems, BLE/IoT, AI, payments, hardware integrations, maps, regulated workflows, or complex architecture that needs senior ownership. 𝐂𝐨𝐫𝐞 𝐄𝐱𝐩𝐞𝐫𝐭𝐢𝐬𝐞 ▪ Android: Kotlin, Java, Jetpack Compose, MVVM, Clean Architecture ▪ iOS: Swift, SwiftUI, native SDKs, platform channels ▪ Cross-platform: Flutter and Kotlin Multiplatform (KMM) ▪ BLE, IoT & hardware: medical devices, robotics, wearables, connected products ▪ Real-time: WebRTC, Socket Programming, Twilio, video, low-latency chat ▪ Maps & location: geofencing, live tracking, routing, custom SDKs ▪ Fintech & payments: wallets, KYC, subscriptions, payment gateways ▪ AI features: streaming chat, character memory, LLM integrations, on-device ML ▪ App rescue: refactoring, crash fixing, performance tuning, architecture cleanup 𝐖𝐡𝐲 𝐂𝐥𝐢𝐞𝐧𝐭𝐬 𝐇𝐢𝐫𝐞 𝐌𝐞 ① The app needs to scale: millions of users, peak traffic, complex state, performance-sensitive flows. ② The app cannot fail: medical, fintech, real-time, hardware, or business-critical workflows where reliability is non-negotiable. ③ The app is technically difficult: BLE devices, AI, native SDKs, WebRTC, payments, maps, or legacy code that needs expert handling. ④ The product needs senior ownership: architecture, technical decisions, tradeoffs, code quality, and delivery without heavy supervision. 𝐇𝐨𝐰 𝐈 𝐖𝐨𝐫𝐤 ▪ I clarify the product goal, technical risks, and success criteria before writing code ▪ I break work into clear milestones, so progress is visible ▪ I share frequent updates and demo videos for major features ▪ I communicate tradeoffs directly instead of hiding problems ▪ I write production-grade code: clean architecture, reliable state management, testing, CI/CD readiness, maintainable structure With 10+ years and 25+ shipped apps (three with 1M+ users), I've worked across fintech, healthcare, AI, robotics, BLE/IoT, real-time communication, and developer SDKs, including public contributions to Amazon Location Service under the AWS Geospatial organization. If your mobile app is complex, high-value, scaling fast, connected to hardware, using AI, handling payments, or relying on real-time data, send me your goal, current stage, and biggest technical concern. I'll respond with a clear plan, a realistic timeline, and the safest way to move forward.

One Person. Full Product. Zero Gap Between Design and Code. What You Approve in Figma Is Exactly What Your Users Get. From First Wireframe to Both App Stores, I Own It All. Hiring a designer and a developer separately sounds logical. Until the designs don't match the app, the developer can't follow the files, and you're stuck in the middle, managing two people who've never worked together. I'm Arfan. 7+ years in UI/UX design and Flutter development equal depth in both. I design your product and build it myself. What you approve in Figma is exactly what ships. No middlemen, no miscommunication, no budget surprises. I've shipped products across fintech, healthcare, e-commerce, SaaS, real estate, food & restaurant, EdTech, and early-stage startups, so whatever you're building, I've likely shipped something close. ✅ Problems I Solve: → When the same person designs and builds, there's no gap. Every component in Figma gets built exactly that way in Flutter. No version two that nobody told the developer about. → Flutter runs natively on both platforms from one codebase. Same quality, both stores, significantly less cost and time. → My files are built for development, auto-layout, named components, spacing tokens, and clear specs. When I'm also the developer, handoff is instant. → I audit the full journey, find where friction is happening, redesign those flows, and rebuild the screens. A real fix, not a theory. → I design dashboards where data hierarchy and user actions come before colours. Functional first, beautiful second. → Clear milestones. Deliverables at every stage. You see progress before paying for the next phase. No surprises, no disappearing. ✅ Design — How I Work: → Users First, Preferences Second: UX research, user flows, and journey mapping before any screen is touched. Beautiful screens on the wrong foundation don't convert. → Wireframes That Actually Think Logic and structure are fully mapped before any visual polish. Structure before style, always. → Production-Ready Figma Auto-layout, reusable components, design tokens, spacing systems. Every file is dev-ready from day one. → Prototypes That Feel Real: Fully interactive prototypes you can click through before a line of code is written. Catch problems early, not after weeks of development. ✅ Development How I Build: → One Codebase, Both Platforms: Flutter for iOS and Android. Clean architecture, smooth performance, built to last beyond launch day. → No Approximations I designed it, so I built it exactly right. Every pixel, every transition, every edge case. No shortcuts. → Scalable Architecture BLoC, Riverpod, or Provider based on complexity. Adding features later won't mean rewriting everything. → Backend & Integrations Firebase, Supabase, REST APIs, Stripe, push notifications, Google Maps, geofencing wired in and production-tested. → Full Store Deployment App Store and Play Store, start to finish. Certificates, metadata, compliance, and release. Done. 🛠️ Flutter, Dart, FlutterFlow, Firebase, Supabase, BLoC, Riverpod, Stripe, Git, Xcode, Android Studio ✅ How It Works: 01 Discovery → goals, users, and constraints mapped before anything else 02 Wireframes → structure and flows defined before visuals or code 03 UI Design → full Figma screens reviewed and signed off before build 04 Prototype → You click through the product before development starts 05 Flutter Build → clean, scalable, and exactly as designed 06 Integration → backend wired and tested on real devices, both platforms 07 Deployment → both stores handled, your app goes live cleanly ✅ Why Me: One hire. Full ownership. Faster delivery. Fewer revisions. Design and development by the same person who understood your product from day one, from the first user flow to the last line of code. No gap between what was designed and what gets built. Click Invite to Job, share your Figma files or idea, and let's get started.
