I understand you require a full native Android app in Kotlin to rebuild your fintech B2B portal with API integration, biometric SDK support, and a lightweight, fast UX similar to SpiceMoney. You need the app to implement secure login with OTP, MPIN, device binding, and modules like AEPS, DMT, and BBPS, avoiding any WebView solution. With over 15 years of experience and more than 200 projects completed, I specialize in Mobile App Development and API Integration, including Kotlin-based Android apps and backend connectivity with PHP and MySQL. My background ensures clean, scalable code following MVVM and Clean Architecture principles that align perfectly with your requirements. I will develop the app using Retrofit for API calls and JSON parsing, integrate biometric authentication via the RD Service SDK using intents, and implement SSL pinning and token-based sessions for security. The dynamic dashboard will load from APIs as specified, and I estimate delivery within 6-8 weeks, focusing strictly on Android app development as requested. Feel free to share more details so we can discuss how to move forward smoothly on this rebuild.

Being an experienced and accomplished Android developer, I have a solid grasp of the stack necessary to execute your project with professionalism and utmost efficiency. My skills in Kotlin, Retrofit, and Clean Architecture perfectly align with your technical requirements. Additionally, my experience in API integration would ensure that your existing backend seamlessly integrates with the native Android app that I am capable of building. In line with your need for a secure login system, I am well-versed in implementing OTP, MPIN, and Device Binding mechanisms that guarantee utmost safety and usability. The inclusion of biometric integration using RD Service (Mantra/Morpho/Startek) via Intent for AEPS support is also well within my purview. To ensure snappy performance akin to SpiceMoney's UX, I prioritize writing clean, lightweight code with minimal dependencies. My solutions are not just limited to the present; I invest time in devising future-proof ideas to ensure the scalability of the project as well as its long-term relevance. Building an aesthetic, user-friendly fintech app that enhances user experience while ensuring security forms my ultimate goal

Hello! As per your project post, you want to rebuild your existing B2B fintech portal into a full native Android app using Kotlin, with proper API integration and biometric based modules, not a WebView solution. My approach will be to develop the application fully in Kotlin using MVVM with Clean Architecture. I will structure the project into presentation, domain, and data layers to ensure long term scalability. Retrofit will be used for secure API integration with proper request interceptors, token handling, and structured JSON parsing. SSL pinning and encrypted shared preferences will be implemented for secure session management. Login flow will include OTP verification, MPIN setup, device binding logic, and biometric authentication where required. RD Service integration for Mantra, Morpho, and Startek devices will be handled via Intent based communication for AEPS transactions. Dashboard and all modules such as AEPS, DMT, BBPS, Recharge, Wallet, Ledger, Flight, PAN, and Loans will be dynamically loaded via backend APIs with proper state handling and error management. I have 7+ years of experience in Android development including fintech style secure applications with biometric integration and token based authentication systems. Estimated timeline for a structured MVP level rebuild is 4 to 6 weeks depending on API readiness and testing cycles. I can share a detailed cost breakdown in chat. Best regards, Pratiksha Gupta
