JOB FOR only & only Jharkhand's Developers

!!! only Need jharkhand based devlopers ***************************************************************************** I am adding several core features to an existing mobile app and I need someone who is physically based in Jharkhand to work with me on-site when required. Here is what has to be delivered: • Razorpay integration that covers the full payment flow—one-time payments, recurring subscriptions, and automated refund processing—using the official Razorpay SDK and webhooks. • Real-time user-to-user chat built into the app with typing indicators, read receipts, and offline message queueing. • A simple in-app feedback module so users can rate their experience and leave comments that post to our backend. • Connection to the “ALAO 3” third-party API (documentation supplied) so the app can fetch, display, and update data through its authenticated endpoints.
