The brief

Build and stabilize a telehealth platform for men's sexual health (ED/PE) enabling seamless patient-to-doctor video consultations, treatment package purchases, and personalized treatment journeys — taking over an existing codebase via KT and extending it with Agora video calling, Razorpay payments, admin panel enhancements, and production deployment on AWS.

What we built

A comprehensive end-to-end telehealth platform for men's sexual health (ED/PE) spanning:

  • Agora-powered video consultation rooms with in-call prescriptions, chat, screen share, recording, and PIP mode
  • a multi-gateway payment system (Razorpay + Cashfree + Pine Labs) with a custom checkout page and GST-aware invoicing
  • a full CRM and sales operations suite with a lead dashboard, DoubleTick/Gupshup WhatsApp automation, dialer integration, slot-booking-pending workflows, and DC team leaderboards
  • structured clinical modules including dynamic patient history forms (ED/PE branching), SHI psychometric scoring, milestone-based therapy tracking, and TP cohort analytics
  • a multi-domain web presence (qurex.in, rxmen.in, wellness, qurexhealth.com) with SEO, SSR, Core Web Vitals optimization, and microfrontend R&D
  • AWS infrastructure with auto-scaling, RDS read replicas, Redis caching, Lambda workers, and load testing; and
  • a progressive backend migration from Express Node.js to NestJS microservices (payment, notification, video services).
⊛ Live in production

Multiple live domains (rxmen.in, wellness.rxmen.in, qurexhealth.com, wellness.qurex.in) with active DC and TP call flows, Cashfree-primary payment processing, WhatsApp notification automation via Lambda, an admin CRM with lead dashboard and DC team revenue tracking, Agora video consultations with audio recording and PIP mode, NestJS microservices (payment, notification) in active development, and SSR-migrated Angular frontend.
