Most mobile apps in healthcare, wellness, and fitness don't fail because of missing features. They fail because they can't handle real-world usage. Slow screens. Broken sync. Unreliable data. And once users lose trust in a health app, they don't come back. That’s usually the moment I get involved. I'm a Senior Mobile App Developer with 15+ years of hands-on experience delivering iOS, Android, and cross-platform apps in healthcare, wellness, fitness, and connected systems where reliability matters as much as innovation. I don’t build quick demos; I build mobile systems that hold up under daily real-world use. A lot of my recent work sits at the intersection of mobile + healthcare + AI + GPS + connected devices. I’m selective about where intelligence and automation go. Features only stay when they improve outcomes or reduce friction. 📱 Mobile Development Expertise • Cross-Platform: React Native, Flutter (production apps) • Native iOS: Swift, SwiftUI, iPad apps • Native Android: Kotlin, Android features • Hybrid/Web: Ionic, WebRTC Focus Areas: • Real-world performance under heavy load • Offline-first systems, sync reliability, and state consistency • Clean, modular architecture • App Store & Google Play readiness 🗺️ GPS & Location Systems I build reliable location-based mobile systems that work in real conditions: • Real-time GPS tracking and route mapping • Background location tracking (battery-optimized) • Geofencing and location-triggered actions • Live location sharing • Fitness route tracking (running, cycling, walking) • Map integrations (Google Maps, Mapbox) These systems are designed to stay accurate even with weak signals, offline usage, and device restrictions. 📡 BLE & IoT Connected Systems I specialize in Bluetooth Low Energy (BLE) and IoT integrations where mobile apps connect to devices and sensors. • BLE device pairing and real-time communication • Wearable integrations (health & fitness tracking) • IoT systems using AWS IoT Core and Azure IoT • Sensor data streaming and sync • Background reconnection and stability handling I focus heavily on reliability: stable connections, clean reconnection logic, and consistent data sync. 🏥 Healthcare, Wellness & Fitness This is where most of my work lives: • Health tracking: vitals, symptoms, dashboards • Fitness apps: workouts, habits, progress systems • Wellness apps: journaling, meditation, mental health flows • Telemedicine: messaging, video consults, scheduling • GPS fitness tracking with real-time route analysis • Wearable + BLE health device integrations 🧠 Smart AI Integration AI is only used where it adds real value: • Personalized fitness and wellness insights • AI coaching and behavioral summaries • Journaling and guided health flows • OCR-based input for tracking • AI combined with GPS + sensor data ⚙️ Backend & Integrations • Node.js / Python (FastAPI) • Firebase & Supabase (real-time sync) • APIs, push notifications, in-app purchases • GPS + IoT data pipelines 📊 Impact • Fixed unstable wellness apps with sync issues • Built GPS-based fitness features with high retention • Delivered health MVPs without rewrites • Improved BLE reliability and reconnection stability • Integrated AI to reduce user friction, not add complexity 💬 How I Work Clients usually reach out when: • Apps break under real usage • GPS or BLE features are unreliable • MVPs need to become production-ready systems • AI needs to be integrated properly I’ll always point out what’s unnecessary early and clearly. 🏆 Additional Services 6 months free maintenance after launch Full IP transfer from day one (client GitHub) Agile development with regular updates App Store & Play Store deployment handled end-to-end I also work with no-code/low-code tools when it makes sense: Bubble, FlutterFlow, Webflow, Lovable, Base44 + AI APIs (Claude, GPT, OpenAI) 🧩 Core Skills Mobile App Development | iOS | Android | React Native | Flutter | Swift | Kotlin | AI Apps | Healthcare Apps | Fitness Apps | GPS Tracking Apps | Location-Based Services | Geofencing | Real-Time Tracking | BLE Development | IoT Integration | AWS IoT Core | Firebase | Supabase | WebRTC | API Integration | HIPAA-aware systems | In-App Purchases | App Store Deployment 🤝 Why Work With Me Healthcare, Fitness, Wellness, GPS, and connected systems aren’t just features. They need trust, stability, and real-world reliability. That’s what I focus on. 📧 Send me your project idea and I’ll give you a clear, practical next step. Rudy Pasillas
