About the Client
The client is a technology-driven healthcare company focused on modernizing care delivery across India by digitally connecting health plans, healthcare providers, corporate organizations, and patients.
With a vision to enable a fully cashless healthcare experience, the organization began by building a digital Outpatient Department (OPD) ecosystem alongside specialized corporate employee health plans.
This initiative became a key component of the client’s broader digital health transformation strategy, designed to make healthcare more connected, accessible, transparent, and efficient.
Background
India’s traditional OPD ecosystem is highly fragmented. Patients often interact separately with hospitals, doctors, diagnostic laboratories, pharmacies, insurers, and payment systems, with limited coordination between them.
This fragmentation created administrative complexity throughout the healthcare journey. Manual processes slowed onboarding and claims, disconnected systems made information difficult to exchange, and limited visibility affected both patient experience and operational efficiency.
The client envisioned a unified digital ecosystem capable of managing the complete healthcare journey from appointment scheduling and consultations to diagnostics, claims, billing, and payments.
The platform needed to connect multiple stakeholders while supporting interoperability, scalability, data security, regulatory requirements, and a seamless user experience.
Achieving this vision required more than digitizing individual workflows. It required an end-to-end transformation of how healthcare stakeholders interacted and exchanged information.
The Challenge
Several structural and operational barriers made scaling a cashless OPD ecosystem challenging.
Fragmented Healthcare Operations: Patients, doctors, laboratories, pharmacies, insurers, and corporate administrators operated through disconnected systems and processes.
Manual Workflows: Paper-based claims, billing, onboarding, and approvals increased administrative effort, turnaround times, and the risk of errors.
Limited Interoperability: Healthcare and insurance systems lacked standardized connectivity, making patient, clinical, and claims information difficult to exchange and validate efficiently.
Limited Transparency: Patients and corporate clients lacked timely visibility into claims, approvals, settlements, and healthcare utilization.
Security & Compliance Requirements: Sensitive Protected Health Information (PHI), identity data, and financial information required robust security controls throughout the platform.
Scalability Requirements: The architecture needed to support a growing network of providers, patients, corporate customers, insurers, laboratories, and pharmacies without compromising performance.
The client needed a role-aware and interoperable digital infrastructure capable of bringing these stakeholders together while delivering efficiency, transparency, and security at scale.
The Solution
The client partnered with Supply Medium to design and implement an end-to-end digital healthcare platform connecting patients, doctors, laboratories, pharmacies, insurers, corporate administrators, and internal operations teams within a unified ecosystem.
Built using AWS and modern application frameworks, the platform was designed around scalability, interoperability, automation, security, and user experience.
Technology & Architecture Framework
Accessible Digital Experience
Patient and corporate-facing applications were developed using React.js and Next.js, creating responsive digital experiences across devices.
Server-side rendering supported performance and discoverability where required, while web applications leveraged Amazon S3 and Amazon CloudFront for scalable content delivery and low-latency access.
HTTPS protected data in transit, while GitHub Actions automated deployment workflows to improve release speed and consistency.
Authentication & Role-Based Access
Amazon Cognito provided centralized identity and authentication capabilities across the ecosystem.
The platform supported multi-factor authentication, corporate Single Sign-On (SSO), and federated identity scenarios.
Role-Based Access Control (RBAC) ensured that patients, doctors, claims teams, corporate administrators, and other users could access only the applications and information relevant to their responsibilities.
Data Security & Governance
Security was incorporated throughout the platform architecture.
AWS WAF provided protection against common web application threats, while encryption, AWS Key Management Service (KMS), and controlled IAM policies protected sensitive clinical, identity, and financial information.
Comprehensive audit trails and access controls strengthened accountability and traceability across platform interactions.
Digitized Healthcare Workflows
Core processes including consultations, claims, billing, and onboarding were digitized using FastAPI-based Python microservices deployed on Amazon EKS.
Services communicated through secured internal APIs, while AWS Application Load Balancer (ALB) managed application traffic.
This microservices architecture enabled individual workflows and services to evolve independently while supporting the broader healthcare ecosystem.
FHIR-Based Clinical Data Layer
HAPI FHIR, implemented using Spring, served as the clinical interoperability layer.
FHIR-based data models enabled standardized exchange of healthcare information between the platform and connected systems, reducing dependence on proprietary data structures and simplifying integration across the ecosystem.
Clinical and non-clinical information was logically separated to strengthen data management and governance.
Performance & Scalability
Amazon EKS enabled containerized workloads to scale according to traffic and resource requirements.
Redis was used for caching frequently accessed information and improving application responsiveness, while Amazon RDS for PostgreSQL provided persistent relational storage.
Separate schemas for FHIR and non-FHIR datasets maintained logical separation between clinical and operational information.
Healthcare Ecosystem Integration
Dedicated FastAPI connectors were developed for external laboratories, pharmacies, insurers, and other healthcare systems.
Each connector could operate as an independent EKS workload, enabling integrations to be developed, deployed, scaled, and maintained without tightly coupling them to the rest of the platform.
Combined with HAPI FHIR, this architecture created a flexible foundation for expanding the healthcare partner network.
Clinical Decision Support
Relevant clinical information and contextual alerts were incorporated into consultation and claims workflows.
By making structured clinical information available at key decision points, the platform helped healthcare professionals and claims teams make more informed and efficient decisions.
Continuous Usability Improvement
Doctors, corporate administrators, claims teams, and other users participated in continuous testing and feedback cycles.
Insights from real-world usage were used to refine workflows, reduce friction, and improve platform adoption across different stakeholder groups.
Platform Components
The digital healthcare ecosystem included multiple specialized portals operating on a shared technology and data foundation:
Onboarding Management Portal — Streamlined onboarding for healthcare providers, partners, corporate customers, and other stakeholders.
Doctor Coordination Portal — Supported consultation management and coordination between physicians, patients, and related services.
Lab Services Coordination Portal — Connected diagnostic workflows and facilitated structured exchange of laboratory information.
Insurance Claims Management Portal — Digitized claims submission, validation, approval, tracking, and related workflows.
Financial Management Portal — Supported billing, payments, reconciliation, and settlement processes.
Corporate Client Administration Portal — Provided corporate customers with tools to manage employee healthcare programs and monitor utilization.
