Senior Android Developer | Kotlin + Jetpack + Firebase + AI | SaaS • HealthTech • Finance Apps 👋 Hi! I’m a highly experienced Android developer and AI engineer with a Bachelor’s in Software Engineering and a Master’s in Artificial Intelligence from the University of Sussex, UK. With a deep passion for clean architecture, cutting-edge UI, and scalable backend integration, I bring years of real-world expertise in delivering production-grade mobile apps across industries — including logistics (Click & Collect), healthcare, and finance. Android Development Expertise: As the Lead Developer of Opus, a custom-built Click & Collect logistics app for VJ Technologies Ltd United Kingdom, I built and maintained a modern, high-performance Android app with: 1. Kotlin & Jetpack (Compose, Navigation, ViewModel, LiveData, Coroutines) 2. MVVM + Clean Architecture for scalable, maintainable code 3. Modular codebase with single-activity architecture using NavHostFragments 4. Complex RecyclerViews, diff utils, and view binding for responsive UIs 5. Image handling with Coil, smart preloading, and error-safe loading states 6. Optimized memory management to avoid leaks and ensure smooth performance 7. Camera management, ai model ONNX integration, facial detection (eye, nose, hands) reaction data extracting using Machine Learning. ✅ Integrated full offline/online state handling, clean separation of UI and domain layers, and robust background job handling for syncing and status updates. ☁️ Backend & API Skills 1. Retrofit + Moshi/Gson for clean, async API integration 2. Firebase (Firestore + Auth + Cloud Functions) for real-time, secure apps 3. AWS Lambda + API Gateway usage for serverless logic and secure endpoints 4. Full error handling with Snackbar/Toast, HTTP status mapping, and retry policies 5. Secure user authentication (Firebase Auth & OAuth2) and encrypted session storage 🧠 AI & HealthTech Projects With a strong academic background in AI, I conducted real research in neurological disease early detection: 1. Developed an AI-driven system for Alzheimer’s detection using MMSE scoring models and natural language interaction 2. Built mobile-first prototype apps that analyze speech, responses, and patterns using ML models for risk scoring 3. Worked with structured medical datasets and integrated with AI pipelines (classification, NLP, risk prediction) 💰 Finance & Productivity Apps I’m also the creator of FlexyMint, a smart personal finance & budgeting app for small business owners. Built using Kotlin with Firebase, it includes: 1. Multi-account syncing 2. Daily/monthly budget breakdowns 3. Local + cloud data storage 4. Real-time analytics with charting 🚀 What Sets Me Apart 1. Clean, scalable code with architecture that’s built for real-world growth 2. Deep experience in both UI/UX and backend/API integration 2. Performance-first mindset — optimized RecyclerViews, memory-safe ViewModels, smart image loading 3. Experience building apps that serve real customers, not just prototypes 4. Fluent in Kotlin, Jetpack Compose, and modern Android design systems 5. Comfortable with agile collaboration, Git, CI/CD, and long-term maintenance 🎓 Education 🎓 Master’s in Artificial Intelligence – University of Essex, United Kingdom 🎓 Bachelor’s in Software Engineering – IIU Kotlin, Android, Jetpack Compose, MVVM, Clean Architecture, Firebase, Firestore, Firebase Auth, Retrofit, Coroutines, RecyclerView, Coil, Navigation Component, Jetpack ViewModel, LiveData, QR Code Scanning, CameraX, Barcode Scanner, ML Kit, Google Face Detection, Biometric Login, AI Mobile Apps, Machine Learning, TensorFlow Lite, MMSE Testing, HealthTech, Alzheimer Detection App, FinTech App, Budget App, SaaS App, Click and Collect, Kotlin Expert, Android Performance Optimization, Memory Leak Prevention, Secure Login, Modular Android, Android Jetpack, REST API Integration, Google Play Publishing, Agile Development, Git, MVVM Android, Firebase Realtime, Smart UI/UX, Cross-Device Compatibility, Android Clean Code
