Kotlin-Based B2B Fintech App Rebuilding

@Srashtasoft

Hi there, I have read your project requirement. You need a fully native Android app (Kotlin) for your existing fintech B2B portal with API integration, biometric support, and scalable clean architecture—similar to SpiceMoney. We will build a native Android app using Kotlin with MVVM/Clean Architecture. All modules (AEPS, DMT, BBPS, Recharge, Wallet, etc.) will be integrated via your existing APIs using Retrofit. RD Services (Mantra/Morpho/Startek) will be integrated via an intent-based biometric flow for AEPS. Security will include SSL pinning, token-based sessions, device binding, and OTP + MPIN authentication. The UI will be optimised for fast, lightweight performance with a smooth UX like leading fintech apps. Questions: ========= Kya aapke APIs properly documented hain (Postman/Swagger)? Kya RD Service devices ka testing environment available hai? Kya aapko Play Store compliance (KYC, privacy policy, permissions) me bhi support chahiye? Expected timeline kya hai for first MVP launch? Best Regards, Srashtasoft Team

With my 7+ years of experience as a seasoned Android developer, I bring to the table not just the technical skills in Kotlin and Java you require, but also a deep understanding of your specific project needs. The fact that I've built highly scalable apps using both Kotlin and MySQL, along with my expertise in the modern Android architecture stack including MVVM, Retrofit, and Jetpack Libraries like LiveData and Room make me an ideal fit for your fintech app rebuilding project. I'm well-versed with API integrations, and with your backend APIs already at hand, I can seamlessly ensure a robust correlation between the front-end and back-end of your app. Moreover, I understand the significance of security in fintech applications firsthand. My proficiency in implementing secure logins using OTPs and MPINs, as well as instituting biometric integrations using RD Services that align with AEPS framework demonstrate my thoughtful approach towards this aspect. Additionally, I place a strong emphasis on performance optimization which would ensure your Kotlin-based B2B fintech app not only meets but exceeds user expectations in terms of agility.

As an accomplished developer with equal command over Flutter, React Native, and Android development, I believe my skillset perfectly aligns with your demand for a Kotlin-based B2B Fintech app rebuild. With extensive experience in both frontend and backend technologies, I can efficiently handle the entire app development process by leveraging your existing API's and bringing them alive in a contemporary and performant interface. Having already worked on apps heavily reliant on APIs like yours, I am well acquainted with Retrofit and JSON parsing which makes me adept at integrating APIs seamlessly. Security being paramount for fintech apps, my proficiency in implementing secure login measures such as OTP, MPIN, device binding and biometric integration following RD Service will ensure your users' confidential financial details stay secured. I understand you need an app that's not only hustle-free but also swift and lightweight like SpiceMoney. Being well-versed with Kotlin's clean code practices and its consequent impact on future scalability, I promise to deliver a high-performing app that prioritizes user experience without any compromise on speed or efficiency. Let's connect so I can understand more intricacies of your project to make this app even better than you envision it now.

Hi, I’ve reviewed your fintech B2B portal and the SpiceMoney reference, and I can rebuild your app as a fully native, high-performance Kotlin application with clean, scalable architecture. I’ll implement MVVM with proper separation, integrate your existing APIs via Retrofit, and ensure secure authentication using OTP, MPIN, and device binding. I also have hands-on experience integrating RD services (Mantra, Morpho, Startek) via intents for AEPS, along with SSL pinning and token-based session handling. The UI will be lightweight, fast, and dynamic, driven entirely by APIs. Before proceeding, I’d like to clarify: do you already have API documentation with error handling standards? Any preferred UI/UX guidelines or should I follow SpiceMoney style? For biometric SDKs, are licenses and testing devices available?

I will rebuild your fintech B2B app in native Kotlin with MVVM architecture, secure API integration (Retrofit), OTP + MPIN login, device binding, and full RD service biometric support (Mantra/Morpho/Startek). You’ll get a fast, lightweight, and scalable app with dynamic dashboard, all modules integrated (AEPS, DMT, BBPS, Recharge, etc.), and enterprise-level security (SSL pinning, token sessions) similar to top fintech apps.

Hello Client, I’ll deliver your native Android app in Kotlin with a unified brand identity, fast performance, and easy maintenance. The app will follow MVVM/Clean Architecture, featuring secure login (OTP, MPIN, device binding), biometric integration via RD Service, and SSL pinning with token-based sessions. Your dashboard and multiple modules (AEPS, DMT, BBPS, Recharge, Wallet, Ledger, Flight, PAN, Loans) will dynamically load via Retrofit API integration. You’ll get clean, documented code with setup instructions and walkthrough for a smooth handover. My expertise spans mobile apps and API integrations, ensuring a lightweight, scalable, and robust solution that surpasses SpiceMoney’s UX. Regards Anton Prinsloo

Hi, Native Kotlin app build kar dunga, WebView nahi. Aapka existing PHP + MySQL backend APIs direct integrate karunga. Scope: * Kotlin + MVVM / Clean architecture * Retrofit based API layer + token session * OTP + MPIN + device binding secure login * Dynamic dashboard from API * Modules: AEPS, DMT, BBPS, Recharge, Wallet, Ledger, Flight, PAN, Loans * RD Service biometric (Mantra / Morpho / Startek) via intent * SSL pinning + encrypted local storage * Lightweight UX similar SpiceMoney type * Clean scalable code + reusable base components Deliverables: * Full native Android codebase (well structured) * Biometric AEPS integration working * Error handling + loader + retry * Build variants (prod / staging) * README + API mapping doc * APK + AAB ready for Play Store Already done fintech / AEPS style apps, so RD service flow familiar. Backend ready hai toh fast delivery possible. Start kar sakte hain immediately. APIs + sample login share kar dein. Contact at (+91) 94543-89834
