Telemedicine platforms are software systems enabling remote healthcare delivery. They typically include video conferencing (doctor-patient visits), patient record management (HIPAA-compliant storage), appointment scheduling, electronic prescription handling, billing integration, and messaging. Platforms range from simple video consult tools to full-featured EHR replacements. Telemedicine engineers work on core infrastructure (WebRTC-based video, latency optimization), healthcare data management (FHIR standards, HL7 integration), compliance (HIPAA, audit logging), and user experience (patient portals, provider dashboards).
