Senior Mobile Engineer | 10+ Years of Expertise in Native, Cross-Platform, and AI-Driven Mobile Solutions I help companies design, build, and scale high-quality mobile applications that are fast, stable, and genuinely enjoyable to use. I’m a Senior Mobile Engineer with 10+ years of hands-on experience, specializing in Android-first development, cross-platform solutions when appropriate, and on-device AI features that add real value to users — not buzzwords. I take products from early concept to production and beyond, thinking holistically about users, performance, scalability, and long-term maintainability. I’ve worked with startups, enterprises, and government teams, and I treat every project as if it were my own product. What I Do Best 📱 Native Mobile Development (Android-First) Android is my home base (Kotlin / Java), with solid experience in iOS (Swift). I focus on: - Clean architecture & maintainable code - High performance in real-world conditions - Stable, production-ready apps that scale 🔁 Cross-Platform — When It Makes Sense - I use Flutter and Kotlin Multiplatform KMP strategically to share logic across platforms without sacrificing native UX or performance. - I choose tools based on product needs, not trends. 🤖 Mobile AI & On-Device Intelligence - I integrate AI directly on mobile devices using TensorFlow Lite, ONNX Runtime, and custom models, including: + Image recognition & segmentation + OCR & document processing + NLP and AI-assisted features + Real-time, on-device inference optimized for mobile hardware I’m especially focused on AI that improves user experience and reliability, not AI for marketing hype. 🧩 SDKs & Reusable Components I’ve built mobile SDKs and shared libraries used in production apps — clean, modular, well-documented, and easy for other developers to adopt. 🎨 UI/UX-Aware Engineering I work closely with design teams and care deeply about how apps feel, not just how they function. Tools & approaches include: - Material Design - Jetpack Compose - Native UI frameworks - Polished, intuitive, and accessible interfaces ☁️ Backend & Web (In Support of Mobile) - While mobile is my core focus, I’m comfortable building and integrating with: - Firebase - RESTful APIs - Custom backend services My backend work always serves the mobile experience: secure auth, real-time sync, media handling, and scalable data flows. Tools & Technologies Mobile: Kotlin, Java, Swift Cross-Platform: Flutter, Kotlin Multiplatform AI / ML: TensorFlow Lite, ONNX Runtime, On-Device ML Cloud & Backend: Firebase, REST APIs Other: Python, JavaScript, PHP, C++ How I Work - Experienced in leading and collaborating within agile teams - Clear communication, realistic timelines, and clean, readable code - Strong believer in long-term product health - Mentor junior developers and support healthy engineering cultures - Comfortable in startups, fast-moving teams, and enterprise environments
