Description

Does your live platform need to support tens of thousands of simultaneous viewers without degradation? Does your video pipeline need to process dozens of streams in parallel?

10 years building and operating these types of infrastructures — for the 24h of Le Mans (32 simultaneous onboard streams), Nike for the Paris 2024 Olympics (5200m² 16K screen), interactive reality TV (750h of live), or AI video surveillance (hundreds of cameras in production).

AWS Media Services (MediaLive, MediaPackage, MediaConvert), FFMPEG transcoding pipelines, HLS/DASH/LL-HLS live streaming, H.264/AV1 codecs — live/VOD OTT platforms, multi-tenant architectures, automated TV channels (IPTV/FAST), video surveillance.

Architecture, IaC (Terraform, CDK), CI/CD, Datadog observability (APM, RUM, Logs), FinOps — from design to production.

AI video surveillance startup (€50M raised, 250+ municipalities, UK & Italy expansion). Platform Engineer squad (10 people): sole developer for the Media API and the video on-demand extraction system.

• Media API developed and migrated to production on a new AWS account (CDK TypeScript, Lambda Python, Datadog), hundreds of operational cameras
• Video on-demand extraction from cameras (RTSP/VPN), S3 cache (download time ÷3), FFMPEG assembly — pipeline orchestrated by Step Functions + ECS
• Multi-camera fusion: up to 4 angles of the same camera combined into a single video with timestamp synchronization
• Refactoring of the WebM 2-pass timelapse encoding pipeline into a sharded architecture on ECS Fargate SPOT ARM64: up to 10 encoders in parallel then FFMPEG merge. Average encoding time reduced from 40 min to less than 15 min, 5h peaks eliminated, costs ÷5, quality preserved for 8x zoom.
