Project Overview:
We need an intermediate Kotlin developer to integrate the Razorpay payment gateway and set up biometric authentication inside our existing fintech app.

Requirements:
We are Fyntra Software, and we need some quick updates done on our existing Kotlin-based Android application. You will need to integrate the Razorpay SDK for subscription payments and set up secure Biometric Authentication (Fingerprint and Face Unlock) using the Android BiometricPrompt API. Code should be clean, modular, and well-documented. Please reach out so we can discuss the details and project scope in chat.

Deliverables:
Working Razorpay payment flow, completed biometric authentication module, and clean updated source code repository. Let's chat to talk about the final codebase delivery and testing.

Please feel free to ask any clarifying questions in chat before submitting your proposal.
