Built with .NET, PostgreSQL, AWS, React, Kotlin & Swift
At DEIENAMI, we take pride in building scalable, secure, and future-ready products for healthcare innovators. This case study highlights our work with a fast-growing health-tech product company seeking a powerful telemedicine solution that could scale across regions, integrate with clinical workflows, and meet strict regulatory and user expectations.
Client Vision & Business Challenge
Our client, a health-tech product company, had a strong vision: to launch a comprehensive telemedicine solution enabling remote consultations, secure health data storage, prescription management, and easy doctor-patient interaction across mobile and web. Their goal was to create a solution capable of:
- Handling high user concurrency across mobile and web
- Ensuring data privacy & regulatory compliance (GDPR, HIPAA)
- Delivering native mobile performance for patient and doctor use
- Offering multi-clinic management, onboarding & monetization workflows
- Being market-ready with a stable MVP and extendable architecture
Our Product Engineering Approach
Our role wasn’t just to “build an app.” We partnered with the client’s leadership and product team from ideation to post-launch, delivering an enterprise-grade solution through our proven Product Engineering Methodology.
Discovery & Planning Phase
- Conducted deep-dive technical consultations with stakeholders
- Mapped out the patient, doctor, and admin workflows
- Designed a scalable system architecture tailored to future needs
Tech Stack Selection
We chose a modern, battle-tested tech stack optimized for performance, extensibility, and reliability:

- Multi-language support for regional expansion
- Future-ready modules like AI-based symptom checkers, lab integration, and chatbot-based triage
Security & Compliance Built-In
We implemented:
- End-to-end encryption for patient records
- Audit logs for all sensitive actions (login, record edits, prescriptions)
- Role-based access control (RBAC) for each module
- Prepared documentation for GDPR audits and HIPAA compliance
Business Impact
📈 5,000+ consultations in first 3 months
⚡ 90% reduction in manual scheduling & prescription errors
📱 High app adoption rate due to clean, native UI/UX
🧩 Modular backend ready for future integration with labs, insurance, and pharmacy APIs
.NET (ASP.NET Core) — Enterprise-Grade Performance & Longevity
We chose .NET as the backend framework for its:
- High performance and security (ideal for handling medical data and real-time APIs)
- Strong ecosystem and Microsoft support, ensuring long-term maintainability
- Cross-platform capabilities, allowing flexibility in deployment (Windows/Linux servers)
- Stability & predictability, which is essential in healthcare systems that must run for years with minimal disruptions
✅ ROI Advantage: Reduces future migration costs and simplifies third-party integrations due to wide industry support.
PostgreSQL — Powerful, Scalable & Open-Source
PostgreSQL is a robust, open-source relational database known for:
- ACID compliance and reliability (a must-have for health records)
- Advanced indexing and querying for efficient analytics
- Extensibility — can be customized as needs evolve
- Zero licensing costs with enterprise-level features
✅ ROI Advantage: Delivers the power of commercial DBs like Oracle without the cost, enabling budget-friendly scale.
AWS — Scalable, Secure Cloud Infrastructure
We deployed the app on AWS to ensure:
- Global availability and uptime using EC2, RDS, CloudFront, and S3
- Security compliance features (HIPAA-ready)
- Autoscaling and backup options for business continuity
- Pay-as-you-go pricing to optimize infrastructure costs based on usage
✅ ROI Advantage: Avoids overprovisioning, reduces hosting overhead, and supports future growth without reengineering.
React — Fast, Modular, & Developer-Friendly Frontend
React allowed us to build:
- A responsive and intuitive UI for doctors, admins, and patients
- Component-based architecture for reusable modules (booking, video call, prescriptions)
- Seamless integration with real-time data and 3rd-party tools (chat, calendar)
✅ ROI Advantage: Enables faster updates, smoother UX, and lower frontend development costs over time.
Kotlin & Swift — Native Mobile Experience
Instead of using a hybrid mobile framework, we went with Kotlin (Android) and Swift (iOS) to deliver:
- High performance and smooth UI/UX on both platforms
- Access to device-specific APIs (camera, biometric, push notifications)
- App store compliance and better security practices
✅ ROI Advantage: Improves user satisfaction and retention, which is crucial for patient and doctor adoption.
Strategic Outcome
This stack was chosen to maximize:
- Long-term sustainability (backed by global tech ecosystems)
- Performance at scale (millions of records, real-time video, security)
- Lower total cost of ownership (open-source + cloud + efficient dev practices)
- Faster iteration cycles for feature rollouts
