Call me to talk about

Datavisualisation

I am highly experienced with D3js framework to produce high level datavizualisations. I worked on several datajournalism articles dealing with French Politics, environmental issues during the COP21. Otherwise, I am used to working on dashboard on business data to produce tactical application coupling datavizualisation and algorithms. For instance, I worked on datavisualization in other fields such as French luxury designer, French Top Electrical producer French Top bank and French Top telecom actor. Mainly in D3js, I worked also on network analysis under neo4j and gephi, and reporting on Tableau software.

Smart Cities

I intensively worked on data analysis and Machine Learning apply on the energetical field. I focused on Time-Series Forecasting, Predict and Classify User Behavior, Detection on Unknown Patterns and Outliers . I have a large knowledge in coupling internal data with external data (open-data, public data, IoT, social media).

Machine Learning

I have been exposed to a large range of statistical problematics. For instance, I have realized several Network Analysis with Social Media data, on Customers data for a Recommendation Engine, on Historical Data using A Temporal Space Model.
I have also good knowledge aboug Machine Learning techniques in NLP ( Latent Dirichlet Allocation, Word2Vec..)

Open Data

I am an Open Data Evengelist and I am speaker about state of arts and evolution in Open Data.
