About Julien

The lockdown and this situation allowed me to train as a data scientist. For over 5 years I have been working with data to classify different wine selections, to present different rental apartments, to compare real estate projects, to automate the reading of scientific PDF files.

Thanks to the R language and the R Studio software, data hold no more secrets for me. I can clean and organize data to make it speak. But above all, I can visualize them using a set of graphs.
Python is mainly useful for me to collect my datasets and automate my monitoring processes.

I have worked in the following sectors: real estate, audiovisual, hospitality, and wine distribution.
I am dynamic, motivated, and open-minded. I have always pushed my limits and I always look far ahead.
Today I want to use all my acquired skills and all my knowledge as a data scientist for your needs.

What can I do for you?

Do you want to benefit from the maximum of your user or customer data and don't know how?
Do you want to classify your prospects or your customers?
Do you need to identify insights from your technical data?
Do you want to gather data (sql, excel, csv, pdf)?
Do you want to understand and visualize your data using graphs?
Do you want to use Natural Language Processing (NLP) to find patterns?
Do you need to identify patterns in your data to continue identifying your targets? To better target your prospects?
Do you want to automate the evolution of your data from your websites or applications?

If you have other needs, do not hesitate to let me know and I will tell you if I can solve your problems...

    La formation était surtout axé sur les techniques liées à l'image et à la communication.
