I specialize in: - on-device AI integration using MediaPipe / TFLite / Google ML Kit (Object detecton , Face and pose detection , Text summarizing / OCR , text-to-speech , speech-to-text , etc.); - building media, social, and everyday tools (not games); - fixing app performance , memory leaks , crashes and ANRs , especially in complex or “vibe-coded” apps. 🌟🌟🌟🌟🌟 Recent feedback : "I was particularly impressed by his strong attention to detail — nothing was overlooked, and the quality of the work consistently met high standards. He showed real commitment to the project, staying engaged and proactive throughout the development process. His regularity and consistency in delivering work made collaboration smooth and reliable." - Neil 🚀 Also I've been building my own Android apps so that gives me a deep understanding of not only a technical part but also ASO and monetization strategy. ✅️ Recent large-scale projects: --- PDF Maker & Reader (130k+ installs , 🌟4.6 on Google Play) Role: Android Developer / Android App Developer / Kotlin Developer I recently built this high-performance Android app from scratch based on Figma mockup using Kotlin.

I help teams build stable, high-performance Android applications by making the right architecture decisions early and fixing them when they weren’t. Most Android apps don’t fail because of bad UI. They fail because of fragile architecture and technical debt. I’m a Top Rated Android Engineer with 4+ years of experience delivering production-ready Android apps where performance, stability, and long-term maintainability actually matter. ❖ What I Do I design, build, and maintain native Android applications using proven engineering practices: ✓ Android App Development • Native Android apps with Kotlin & Java • Jetpack, Jetpack Compose, Android SDK ✓ Architecture & Code Quality • MVVM & Clean Architecture (used only when it makes sense) • Refactoring fragile or messy codebases • Reducing long-term technical debt ✓ Performance & Stability • Fixing crashes, ANRs, and memory leaks • Performance profiling and optimization • Production issue debugging ✓ Long-Term App Ownership • Adding complex features safely • Maintaining and scaling existing apps • Taking over apps that need stability and direction ❖ How I Work I don’t start by writing code. Before implementation, I focus on: • Where will this app break in 6 months? • Which parts will be hardest to maintain? • What can be simplified now to save time and money later? Then I design solutions that are: • Predictable to scale • Safe to extend • Easy for other developers to understand I don’t over-engineer. I don’t under-engineer. I engineer for real-world use. ❖ Tools & Technologies ✓ Languages: Kotlin, Java ✓ Android: Android SDK, Jetpack, Jetpack Compose ✓ Async: Coroutines, Flow ✓ Data: Room, Retrofit, Firebase ✓ Media: ExoPlayer ✓ Architecture: MVVM, Clean Architecture ✓ Workflow: Git, Gradle (Strong tools matter — but good decisions matter more.) ❖ Why Clients Hire Me ✓ Top Rated with a proven track record ✓ Strong focus on performance & stability ✓ Honest feedback — even when it’s uncomfortable ✓ Clear communication and realistic expectations ✓ Long-term mindset, not quick fixes If your project is small, I’ll tell you. If something is a bad idea, I’ll tell you. That honesty is why clients rehire me. 🚀 Let’s Work Together I’m not the right fit if you’re looking for the cheapest Android developer. But if you want someone who will think, question, and protect your product, let’s talk. 📩 Send me: • What your app does • What’s currently not working • Where you want it to go I’ll tell you honestly how I’d approach it.

"I build Android apps that don’t just work—they scale." Most developers can build an app for 1,000 users. I specialize in architecting Native Android ecosystems designed for 10 to 15 Million users. With 3.5+ years of experience and a current role as a Senior Android Developer at SoftAxes Technology, I bring enterprise-level stability and high-velocity engineering to every project. 🚀 Velocity & Results I prioritize efficiency without compromising code quality. At my current firm, I recently delivered a production-ready System Utility app with 13 core features in just 6 working days. I achieve this speed by using modern architectures like MVI (Model-View-Intent) and strict Clean Architecture, ensuring that logic is decoupled, testable, and ready for rapid growth. 🤖 AI & The Modern Stack I stay ahead of the curve by integrating Generative AI (Gemini/OpenAI) into mobile solutions to create "smart" features that drive user retention. My technical foundation is built on: Languages: 100% Idiomatic Kotlin & Java. UI: Jetpack Compose, Material Design 3, and custom animations. Architecture: MVI, MVVM, Clean Architecture, and Modular Design. DI & Local Data: Dagger-Hilt, Koin, Room Database, and SQLCipher. Networking: Retrofit, OkHttp, and WebSockets for real-time data. Background Ops: WorkManager and Foreground Services for high-reliability background tasks. 🏆 Why Work With Me? I maintain a 100% Job Success Score because I treat every project as a business partnership. My experience collaborating with global firms like Ikame Global and Appvestor has taught me that the most expensive mistake a startup can make is "cheap code" that has to be rebuilt. I build it right the first time. My Expertise Covers: High-scale Marketplaces (C2C, B2B, Escrow logic) Fintech & Payment Gateways (Safepay, JazzCash, EasyPaisa, Stripe) System Utilities & Phone Cleaners Real-time Navigation & GPS Tracking Content Delivery & Media Apps (4K Wallpapers, AI Content) If you are looking for an Android Architect who understands the difference between an MVP and a Scalable Product, let’s connect. I’m happy to discuss a technical roadmap for your vision.
