Problem

Legacy patient portal software caused long appointment booking queues, confusing multi-step forms, and frequent session timeouts. Healthcare coordinators spent over 25 hours weekly manually confirming patient schedules and following up on biometric monitoring check-ins.

Solution

We developed a high-performance, accessible Next.js patient web portal paired with a secure microservice backend. The portal integrates directly with existing electronic health records (EHR) via HL7/FHIR APIs, offering one-click appointment rescheduling, instant SMS reminders, and real-time vital telemetry logging.

Stack

  • Frontend Platform: Next.js App Router, React 19, TypeScript strict mode.
  • Accessible Design System: Tailwind CSS v4 tokens, Radix UI dialog and accordion primitives.
  • Backend Infrastructure: Node.js & Go microservices, PostgreSQL with encrypted at-rest records, Redis cache.
  • Compliance & Security: HIPAA-compliant audit logging and role-based access control.

Outcome

  • 94% patient adoption rate achieved within the first 90 days of deployment.
  • No-show appointments reduced by 38% with automated Cal.com and SMS reminder workflows.
  • 100% WCAG 2.1 AA compliant UI tested with automated Axe and screen reader verification.
