Screenify - streaming service with 100,000+ content

I managed to achieve a page load time of less than 1 second, even with a database of over 100,000 content items. This allowed to reduce the bounce rate by 25% and cut customer acquisition costs by 15%, saving over $2,000/month on marketing.

The client contacted us through a freelance platform with the idea to create a streaming service for movies and TV shows, accessible on the web, mobile devices, and Smart TV. The main goal is to create a scalable product with a premium UX.

Project tasks:
1. Scalable infrastructure — ensure stable operation under high load
2. Own analytics and CRM — tracking user behavior, views, searches, and integration with user analysis systems
3. Modern design — convenient, aesthetic, and intuitive interface
4. Mobile and TV applications — optimized for Android, iOS, and Smart TV
5. Powerful streaming system — subscriptions, resume watching from any device, recommendations, search
6. Payment integration — subscriptions, payment management, monetization

What I implemented within the project:
1. Performance optimization with Redis and Next.js — caching and SSR provided ultra-fast loading
2. Offline mode support and AirPlay — users can download videos and stream to other devices
3. Reliable database — PostgreSQL (clustering and sharding) for content + MongoDB for individual data
4. CDN and load balancer — custom DNS-based solution for efficient video delivery
5. Smart analytics — deep tracking of user sessions, habits, and engagement linked with CRM

Screenify today is a scalable, fast, and user-friendly streaming service for content viewing on any device.
