During 10 years, I built and collaborated on many differents types of webapps. Today, I'm using React a lot.
At Tweetping, I developed a strong expertise in big data, specially in the way to represent data and make it comprehensive.
I'm very familiar with realtime interfaces and realtime protocols for webapp (as Webscokets or ServerEvent).
Nodejs, Redis, Docker... Are my favorite tools to create microservices architectures, to scale, and to manage processes.
