As the technical lead for a multimedia streaming service, my goal was to launch an Ad Video on Demand (AVoD) and live TV service from scratch on all major consumer platforms within six months.

• Successfully launched the streaming service on the top seven consumer platforms within six months with 100,000+ VoD assets and 60+ live channels. Subsequently, added several additional platforms and doubled the content.
• Created a new revenue stream with dynamic ad insertion while maintaining the perceived ad load for the user. Extended existing broadcast workflows for accurate content stitching.
• Designed a system that outperforms state-of-the-art broadcast experiences (playback lifecycle, channel switching, monetization) and ensures quality metrics remain excellent even during high-profile events.
• Built a distributed streaming platform with 99.99 % monthly availability for VoD, live TV and event streaming (ingest, transcoding, packaging, distribution).
• Built and managed two DevOps teams from scratch to scale the service and ensure 24/7 on-call operations.
• Launched content protection systems on all platforms to enable Subscription Video on Demand (SVoD) capabilities for Hollywood studio content.

This streaming platform serves millions of European viewers every day and has been battle-tested during several high-profile sporting events.
