As Android Developer / Mobile Developer with 10 years of experience I'm helping small businesses, startups, and indie founders translate their vision into scalable, high-performance apps from 0 to launch, launch MVP in weeks, integrate on-device AI and upgrade apps to comply with the latest Google Play requirements. In 2026 I specialize in: - on-device AI integration using MediaPipe / LiteRT / Google ML Kit ( Object detecton , Face detection , Pose detection , Text summarizing / OCR , text-to-speech , speech-to-text ); - video / media editing apps ( FFMpeg , AndroidX Media3 ); - building media , social , and productivity 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. It allows users to quickly convert images to PDF and edit existing PDFs using a fast, local-first architecture. The app has achieved 130k+ downloads and 8k monthly active users on Google Play, with the crash rate lower than 0.1%. --- --- US Medical Education App (COMQUEST for COMLEX & COMAT Prep) Role: Android Developer / Android App Developer / Mobile Developer As part of an international team alongside iOS Developer and Web Developer, I built this Android app from scratch based on Figma designs for US medical students. Continue providing ongoing support for this project, ensuring the mobile app remains a stable and reliable tool for users. --- --- US Automotive Video Suite app Role: Android Developer / Android App Developer / Mobile Developer In collaborating with an iOS Developer and a Full Stack Developer, I built two native Android apps from scratch as a clone of iOS apps (Dealer Video Inventory and Dealer Video Suite) that allows dealers to capture high-quality vehicle inventory videos and photos. These projects helps dealers increase sales through personalized video. --- 🌟 🌟🌟🌟🌟 "Dmitri is a pleasure to work with. He's Android programming skills are exceptional. He's always professional and easy to work with. He is very methodical in his approach. Which at times has resulted in delivery scheduling slipping a little but I rather have a good product than a hastily put together product. We're continuing to work with Dima for other projects." - Philip Whether you are looking for a Mobile Developer to lead a new project or an Android Developer to optimize an existing Java / Kotlin codebase or optimize performance, my goal is to provide technical clarity and long-term stability. As a team player for cross-platform projects I have a proven track record of working alongside iOS developers to ensure smooth releases. I also have specific experience collaborating with Flutter Developers and Full Stack Developers to bridge the gap between cross-platform Flutter / React Native code and the system features specifically by developing custom Java / Kotlin modules to handle native Android OS functionality that standard Flutter plugins can't reach. --- 🚀 My core stack: 🔸️Languages: Java , Kotlin 🔸️UI: XML , Jetpack Compose 🔸️Architecture: MVVM , MVI , Clean Architecture 🔸️Native: Android SDK , Android Studio 🔸️Multiplatform: Kotlin Multiplatform ( KMM / KMP ) / Compose Multiplatform ( CMP ) 🔸️Key features: Camera , Photo & Video capture and edit using FFMpeg , OpenGL , OpenCV ; GPS , Location , Chat , Background syncronization , WorkManager and foreground services, ofline-first approach, on-device AI / LLM , VPN / WireGuard , ExoPlayer / Media3 🔸️On-device AI integration : Video analysis , Image recognition , Object detection , Face detection , Pose Detection , Camera stream analysis , Text-to-Speech , Speech-to-Text ( MediaPipe / Google AI Edge , TensorFlow / TFLite , Google ML kit ). 🔸️Cloud AI integration : OpenAI , Gemini API

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.
