🏆 Senior Mobile Game Developer - 7+ Years Shipping Games That Earn I build mobile games that people play, pay for, and return to. Over 7+ years, I've taken games from concept to global launch on iOS and Android - owning the full lifecycle: game design, core-loop engineering, backend, LiveOps, analytics, and monetization. My titles have generated 10K+ downloads and 50K+ revenue, and I specialize in the rarest combination in this market: game-feel engineering + on-device AI/computer vision + revenue design. If you need a developer who treats your game as a business - not just a build - you're in the right place. 🎮 Mobile Game Development - Full-Cycle Ownership ✅ Engines & Frameworks: Unity (C#), Flutter (Dart) with Flame, native iOS (Swift/ARKit) & Android (Kotlin) ✅ Core Systems: 60fps game loops, physics, real-time input pipelines, progression & ranking systems, reward economies, daily quests, battle passes, leaderboards ✅ Backend & LiveOps: Firebase, PlayFab, Node.js, cloud saves, remote config, A/B testing, event-driven live content ✅ Store Excellence: App Store & Google Play submission, ASO, review-guideline compliance, phased rollouts, crash-free releases (99.9%+ stability) I've shipped hybrid-casual, fitness/motion, and family-audience games - genres where retention is won or lost in the first 90 seconds of gameplay. 🤖 On-Device AI, Computer Vision & Motion Detection This is my sharpest edge. I build camera-based, real-time motion games where the phone sees the player: ✅ Pose Estimation: MediaPipe (BlazePose), MoveNet, custom TensorFlow Lite & Core ML models ✅ Real-Time Performance: GPU/NNAPI delegate optimization, sub-50ms inference, keypoint smoothing (Kalman / One-Euro filters), thermal & battery management for long sessions ✅ Gesture & Strike Classification: velocity-vector analysis for punch/swing/rep detection, accuracy tuning across lighting conditions, camera angles, and low-end devices ✅ AR & Sensors: ARKit, ARCore, sensor fusion (IMU + vision) Motion-controlled gameplay only works when detection feels instant and fair - I engineer for exactly that. 📈 Retention, Progression & Monetization - Games as a Business I design economies, not just features: ✅ Retention Engineering: D1/D7/D30 optimization, FTUE (first-time user experience) design, session pacing, streak & habit loops - I've lifted on a live title by rebuilding onboarding into the core loop ✅ Monetization: subscriptions, IAP economies, rewarded ads, hybrid models, price testing, LTV/ARPDAU growth ✅ Family-Safe Revenue: COPPA, GDPR-K & UK Children's Code compliance, Apple Kids Category and Google Play Families policies - monetizing mixed kid/adult audiences without store rejections or regulatory risk ✅ Analytics: Firebase, GameAnalytics, Amplitude, funnel & cohort analysis, data-driven roadmaps ⚡ AI-Accelerated Development - Claude Code & Modern Tooling I build fast without sacrificing quality. My daily workflow includes Claude Code, Cursor, and Copilot for rapid prototyping, refactoring, test generation, and CI/CD automation - routinely compressing weeks of work into days. I combine AI velocity with senior-level judgment: clean architecture, code review discipline, and maintainable systems your next developer will thank you for. 📱 Broader Mobile & Software Expertise Beyond games, I deliver: cross-platform app development (Flutter, React Native), REST/GraphQL APIs, cloud architecture (AWS, GCP), payment integration (Stripe, RevenueCat, StoreKit), push/engagement systems, video & camera pipelines, and companion apps for physical/IoT products - including hardware-paired experiences where a physical product drives app adoption. 🤝 How I Work - Ownership Mindset 🔹 I take vision and run with it - you get a strategic partner, not a task-taker 🔹 Clear milestones, demo builds, and business-language reporting (retention, revenue, growth - not jargon) 🔹 Long-term thinking: scalable architecture, live-ops roadmaps, and games designed to grow for years 🔹 Fluent communicator with founders and non-technical teams 💬 Let's Build Something Players Love - and Pay For If you're launching a mobile game, a motion/camera-based experience, an app paired with a physical product, or need to turn an existing game into a revenue engine - message me. I'll respond with specific, actionable thinking about product, not a template.
