The Challenge
The client needed a secure, high-quality platform for physiotherapy training videos, connecting users with certified specialists, protected video streaming, subscription-based access, progress tracking, and content management. The solution had to be fast, production-ready, and scalable without compromising quality.
No existing platform
Need for secure HLS streaming
Advanced subscription & billing system
User–specialist matching
Health path tracking
Fast delivery timeline
The Solution
I designed and built a complete SaaS platform using Next.js, Node.js, Strapi, PostgreSQL, and AWS (S3 + CloudFront). The platform includes secure HLS/DASH video delivery, a real-time chat, user-specialist matching, analytics, and a full admin panel powered by Strapi. Everything is deployed with a scalable AWS + Vercel + Docker infrastructure and has operated with zero downtime since launch.
