The brief

Build and scale a white-label, multi-tenant employee healthcare management platform enabling HCL Healthcare to onboard large enterprise clients, manage their health check packages and appointment workflows end-to-end, and provide employees with a seamless self-service health benefits portal — replacing manual operations and fragmented tools with a unified digital ecosystem.

What we built

A comprehensive end-to-end employee health management SaaS platform ("Healthbook" / "Habit Health") serving enterprise B2B clients. Deliverables include:

  • Dual-portal web app — internal admin/agent/clinical-agent portal and external employee-facing portal — for appointment booking, health package management, group/tenant management, and bulk HR operations
  • Multi-tenant configuration engine with custom subdomains, domain-email validation, Drools-based eligibility rules, and partner/DC management
  • Flutter mobile app (Habit Health) with Razorpay payments, UPI deep-linking, Shorebird OTA updates, and Fastlane CI/CD
  • WhatsApp appointment booking flows and an AI-powered chatbot replacing a static decision tree
  • Corporate wellness cohort dashboards, personalized smart reports with biological age and risk prediction, and CleverTap behavioural analytics (30+ events)
  • AWS SQS/Batch-powered bulk onboarding and onsite health-camp management pipelines
  • Clinical quality management (CQM/CQE) platform with audit form versioning, scoring, compliance gap tracking, and 65-index MongoDB optimization
  • PDF split/merge utility, HTML mailers, and Webflow/Lottie-animated wellness engagement pages.
