Razorpay Integration & Text Chat

I already have the PickCab Partner Android app live on Google Play ([login to view URL]). I now need two additions: 1. Integrate the Razorpay payment gateway end-to-end, handling order creation, callbacks, success / failure states and error logging, then pushing a new build to internal testing so I can see live payments working. 2. Add a real-time, one-to-one text-only chat inside the app so drivers and riders can message each other. Basic features I expect are time-stamps, typing indicator and push notifications when the app is in the background. You are free to use Firebase, [login to view URL] or any solid alternative. No extra authentication screens are necessary; the new modules should plug straight into the existing flow. Deliverables: • Updated, well-commented source code with Razorpay SDK and chat module integrated • Signed AAB + APK for testing along with a short hand-off document • Video or screen-recorded proof of successful payments and chat messages on both foreground and background states Let me know your fixed price and exact turnaround time so I can lock in the milestone and get this moving right away.
