Valentin en quelques mots

I am a French data scientist with experience working in startups of different sizes and scales, in Australia (Sydney), France (Paris), and Germany (Berlin)

I have experience building ML pipelines that have to serve predictions under high load (millions to billions of events per day) and low latency (few milliseconds). (TensorFlow, TFS, Kubernetes, Scala)
