I build mobile apps where performance, reliability, and technical execution directly affect the business. My work includes official Amazon Location Service Android SDKs, ONWARD Medical ARC-EX, an FDA-cleared spinal cord stimulation system, and Fibe, a fintech lending app with 10M+ downloads. I am usually hired when the project involves more than standard app screens: real-time systems, BLE/IoT, AI, payments, hardware integrations, maps, regulated workflows, or complex architecture. 𝐂𝐨𝐫𝐞 𝐄𝐱𝐩𝐞𝐫𝐭𝐢𝐬𝐞 • Android: Kotlin, Java, Jetpack Compose, MVVM, Clean Architecture • iOS integration: Swift, SwiftUI, native SDKs, platform channels • Cross-platform: Flutter and Kotlin Multiplatform for Android and iOS • BLE, IoT, and hardware: medical devices, robotics, RFID, connected products • Real-time systems: WebRTC, Socket programming, video streaming, low-latency chat • Maps and location: geofencing, live tracking, routing, custom SDKs • Fintech and payments: wallets, KYC flows, subscriptions, payment gateways • AI mobile 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, low-end devices, and performance-sensitive flows. 2. The app cannot fail Medical, fintech, real-time, logistics, hardware, or business-critical workflows where reliability matters. 3. The app is technically difficult BLE devices, AI features, native SDKs, WebRTC, payments, maps, or legacy code that needs expert handling. 4. The product needs senior ownership Architecture, implementation, 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 with clean architecture, reliable state management, testing, CI/CD readiness, and maintainable structure I am the right fit if your mobile app is complex, high-value, scaling fast, connected to hardware, using AI, handling payments, relying on real-time data, or currently suffering from poor architecture. If that sounds like your project, send me your goal, current stage, and biggest technical concern. I will respond with a clear plan, a realistic timeline, and the safest way to move forward.
