I am French with a Post Ph.D in Machine Learning1. Furthermore I love web programming and design.

I am currently working remotely for Cisco Security team as a Clojure Software Engineer.

Previously I worked for Vigiglobe. The first six months I worked with node.js (API/MongoDB/Web). Then we upgraded our stack to Clojure, Haskell, Mesos, Kafka, Druid, etc… At that time we were two to make all technical decisions. In the end we made a real time analytics of social media content on a scalable architecture. Actually our architecture is able to manage (Aggregation & Machine Learning) thousands of messages per second.2 In particular, I’ve written an Haskell twitter stream absorber able to handle thousands of tweets per seconds. And I coded myself a real time sentiment analysis module taking algebraic properties into account to optimize its efficiency.

For an almost exhaustive list of my projects, you could check my github account:
