About Me I am an Android developer skilled in Kotlin, XML, and MVVM architecture. I build clean and modular mobile applications with features like user authentication, API integration, and payment systems. I focus on delivering fast and reliable MVP apps. Why choose me for your Android project? • Modern Android Development: I build clean and reliable apps using Kotlin, XML (ViewBinding), and MVVM architecture for better performance and scalability. • Payment Integration Ready: Experience working with Razorpay and basic PhonePe integration, with simple escrow flow handling. • Firebase Integration: I use Firebase for authentication and real-time data, making it easy to manage users and admin features. • Fast MVP Delivery: I can provide a working UI/demo within 2–3 days to show clear progress. • Modular Code Structure: The app is built in a way that allows easy addition of features like chat, ratings, and notifications later. • Reliable Support: I provide clear documentation and support to help you run and maintain the app smoothly.
