The Challenge

What We Were Up Against

Solving healthcare's most complex technical and compliance challenges at enterprise scale.

Fragmented Data Systems

Patient data was siloed across 12 incompatible legacy EHR systems with no unified API layer, making cross-state care coordination impossible. Data migration alone required processing 18M+ patient records without downtime.

HIPAA Compliance at Scale

Every element of the platform — storage, transit, video streams, audit logs — required HIPAA-compliant architecture. Zero shortcuts could be made while ensuring low-latency performance for thousands of concurrent video consultations.

Real-Time Video at Scale

Supporting 5,000+ simultaneous video consultations with sub-100ms latency, automatic failover, and mobile compatibility across iOS, Android, and Web — without sacrificing video quality or call reliability.

Complex Billing Automation

Healthcare billing involves insurance verification, ICD-10 coding, claim submission, co-pay calculation, and denial management — all requiring real-time integration with 14 different insurance providers and payment gateways.

Scalability Under Peak Load

Morning appointment rushes created unpredictable 10× traffic spikes. The system needed elastic auto-scaling that could provision capacity in under 30 seconds without cold-start latency issues.

Cross-Platform UX

Patients ranged from 18 to 85 years old across varied devices and internet speeds. The UX had to be intuitive for first-time users on 3G connections while remaining feature-rich for power users on desktop.

Goals & Objectives

What Success Looked Like

Clear, measurable objectives defined at the outset. Every technical decision was evaluated against these targets.

Reduce Patient Wait Time

Cut average appointment wait time from 45 minutes to under 15 minutes through smart scheduling.

Increase Doctor Productivity

Enable each doctor to see 40% more patients per day via streamlined digital workflows.

Cloud-Native Infrastructure

Build on AWS with auto-scaling, 99.9% uptime SLA, and full disaster recovery capability.

Full HIPAA Compliance

Pass all HIPAA security audits and achieve SOC 2 Type II certification within 6 months.

Our Solution

How We Built It

Kawach Technology designed a cloud-native, microservices-based telehealth platform built from the ground up for HIPAA compliance, elastic scalability, and exceptional patient experience.

We began with a 3-week discovery sprint — embedded with the client's clinical and operations teams — to map every patient journey, identify integration touchpoints with existing EHR systems, and define the infrastructure architecture.

Architecture Strategy

The platform is built on a microservices architecture deployed on AWS ECS Fargate, ensuring each service (scheduling, video, billing, notifications) scales independently based on real-time demand. A GraphQL API gateway unifies 14 backend services into a single, efficient data layer.

UX Approach

We conducted 40+ user interviews across patient demographics (18–85 age range). The UI follows a progressive disclosure model — complex features revealed only when needed — resulting in a 94% task completion rate in usability testing.

Key Achievements

Why This Project Matters

Beyond the numbers — this platform has improved healthcare access for patients in underserved communities across 12 US states who previously had no access to specialist care.

HIPAA-Compliant from Day One

Not retrofitted — designed with HIPAA as a core architectural constraint from the first line of code.

Zero Downtime Migration

Migrated 18 million patient records from 12 legacy systems to the unified platform with zero service interruption.

Multi-State Rollout in 6 Weeks

After initial launch in 3 states, scaled to all 12 states with no additional infrastructure work required.

Cloud-Native Auto-Scaling

Handles 10× traffic spikes automatically — peak morning appointment rushes processed without latency.

Improved Rural Healthcare Access

Patients in rural counties now access specialist consultations within 24 hours vs. 6-week average travel-based wait.

AI-Powered Clinical Notes

Ambient AI documentation saves each doctor 45 minutes per day — equivalent to 3 extra patient appointments.

FAQ

Common Questions

Have more questions? Book a call with our team.

How much does telehealth platform development cost?

Custom telehealth platforms typically range from $80,000 to $500,000+ depending on complexity, integrations, and compliance requirements. Our solutions start at $80K for a core MVP. We provide detailed fixed-price proposals after a discovery sprint. Contact us for a scoping call.

How do you ensure HIPAA compliance throughout development?

HIPAA compliance is a first-class architectural concern — not an afterthought. We conduct a full HIPAA risk assessment at the start, sign BAAs with all vendors, implement AES-256 encryption for all PHI, enforce role-based access control, maintain immutable audit logs, and engage third-party pen testers before go-live.

What technologies are best for healthcare software?

For healthcare platforms we recommend React/Next.js for frontend (proven performance and accessibility), Node.js or Python for backend (large talent pools, strong libraries), PostgreSQL for structured clinical data, AWS for cloud infrastructure (HIPAA-eligible services), and WebRTC or Twilio for video consultations.

Can the platform scale globally?

Yes. The platform is built on AWS with multi-region deployment support. It is currently live across 12 US states and designed to support international expansion. Internationalisation (i18n), currency, and regional compliance (GDPR, PIPEDA) can be added as layers.

How long does healthcare app development take?

A full-featured telehealth platform like MedCore's takes 5–7 months for enterprise scale. A focused MVP covering video consultation + scheduling + patient portal can be delivered in 10–14 weeks. We recommend a 2-week paid discovery sprint before committing to a full timeline.

Do you provide post-launch support and maintenance?

Yes. We offer tiered support packages from basic bug-fix SLAs to full managed service with 24/7 monitoring, proactive performance optimisation, and ongoing feature development. MedCore is on our Managed Growth plan with a dedicated Kawach engineer embedded in their team.
