Experience
- medici.tvChief Technical OfficerCULTUREDecember 2018 - June 2022 (3 years and 6 months)Île-de-France, FranceMedici.tv: the leader in online classical music.As head of tech and data strategy, I redeployed all our resources on AWS, modernized our application with a dedicated front-end (vue.js), and introduced serverless services. A data-driven architecture allowed us to optimize real-time calculation of audience, royalties, and recommendations using machine learning (Kafka, Elasticsearch, AWS Athena).I resolved video streaming issues in peripheral regions (Asia, Oceania, South America) with a custom, low-cost CDN despite hundreds of terabytes of video files (Cloudfront, Queue, Lambda).Result: doubled subscriber base since I joined.
