Paramount+ App

Project Overview

Paramount+ represents one of the most ambitious streaming platform launches in recent history, consolidating content from CBS, Paramount Pictures, Nickelodeon, MTV, Comedy Central, BET, and Smithsonian Channel into a unified global streaming experience.

During the pivotal Viacom-CBS merger, we worked as an integrated extension of the internal ViacomCBS engineering teams to develop and maintain the Paramount+ mobile applications across iOS, Android, and AppleTV platforms. Our team was deeply embedded in the client's agile workflow, participating in daily standups, sprint planning, and architectural decisions alongside their core engineering organization.

The platform delivers premium content including blockbuster movies, exclusive originals like Star Trek: Discovery and The Good Fight, live sports coverage including NFL on CBS and UEFA Champions League, and thousands of episodes from beloved franchises across the ViacomCBS content library. Our implementation focused on delivering broadcast-quality 4K HDR streaming with robust DRM protection, offline download capabilities, and seamless multi-device synchronization.

Our Role & Responsibilities

Technical contributions and key deliverables

Native Mobile Development

Architected and developed native iOS features using Swift 5+ with VIPER clean architecture pattern for maintainable, testable codebase with reactive programming patterns
Implemented FairPlay DRM-protected video player integration supporting 4K HDR playback with adaptive bitrate streaming (HLS/DASH) and offline download capabilities
Built robust offline download functionality with content expiration management, storage optimization, and background sync for premium subscribers across all platforms
Optimized rendering performance and memory management for smooth 4K streaming on resource-constrained mobile devices with adaptive quality switching

Enterprise Collaboration

Integrated directly with ViacomCBS internal engineering teams across Los Angeles, New York, and London offices in scaled agile framework (SAFe)
Participated in daily standups, bi-weekly sprint planning, and quarterly roadmap alignment sessions with product and engineering leadership
Conducted thorough code reviews, established coding standards, and mentored junior developers on iOS and Android best practices with documentation
Coordinated closely with client QA organization on test strategy, automation frameworks, and release validation across extensive device matrix

Technical Implementation

Integrated Braze SDK for sophisticated push notification campaigns, in-app messaging, and user engagement analytics with A/B testing capabilities
Implemented NewRelic for comprehensive crash analytics, performance monitoring, and real-time alerting with custom instrumentation and dashboards
Established CI/CD pipelines with Jenkins and Fastlane for automated building, testing, and deployment to TestFlight and Google Play Console
Managed beta deployment programs through TestFlight (iOS) and AppCenter (Android) with phased rollouts and crash-free release monitoring

Streaming & DRM

Implemented FairPlay (iOS/tvOS), Widevine (Android), and FairPlay Streaming (AppleTV) with secure key exchange and MPAA-compliant content protection
Built adaptive bitrate streaming with intelligent buffer management, quality switching algorithms, and seamless transitions without playback interruption
Created multi-device synchronization system with conflict resolution, offline-first architecture, and background synchronization for watch state and favorites
Integrated TV Provider Authentication for cable subscriber access with SAML/OAuth flows and entitlement verification across all supported platforms

Technical Challenges & Solutions

Complex problems we solved during development

DRM & Content Protection

Challenge: Premium Hollywood content required MPAA-compliant DRM protection across multiple platforms with zero tolerance for security breaches
Solution: Implemented FairPlay (iOS), Widevine (Android), and FairPlay Streaming (AppleTV) with secure key exchange, certificate pinning, and hardware-backed keystore
Result: MPAA-compliant content protection with zero security breaches during production operation and successful studio audits

4K Streaming Performance

Challenge: Delivering 4K HDR content on mobile devices with varying network conditions and limited bandwidth availability
Solution: Implemented adaptive bitrate streaming with intelligent buffer management, quality switching algorithms, and predictive pre-fetching based on network conditions
Result: 99.5% playback success rate with seamless quality transitions, minimal rebuffering, and <2 second video start time

Offline Download Management

Challenge: Managing downloaded content with licensing windows, storage constraints on mobile devices, and synchronization across multiple user profiles
Solution: Built content lifecycle management system with automatic expiration, intelligent storage optimization, download queuing, and background refresh for expired content
Result: Efficient storage utilization with 40% reduction in cache size through intelligent compression and 99.2% download success rate

Multi-Device Synchronization

Challenge: Maintaining watch state, favorites, continue-watching, and user preferences across iOS, Android, AppleTV, web, and smart TV platforms
Solution: Implemented real-time sync with conflict resolution, offline-first architecture with background synchronization, and event-driven state propagation
Result: Seamless cross-device experience with <2 second sync latency, 99.9% data consistency, and graceful degradation on poor connections
