“Ive always had a strong appetite for digital,” says Renaud Colin. This Jurassia, installed near Lons-le-Saunier, learned to tame software and computer databases to extract information useful to businesses. An experience that he has gained over time after having worked for ten years in the Department of Law in the field of GIS platforms (geographic information systems). Today his daily life consists of 'web tracking', 'business intelligence' and 'data visualization'.

“When I started my company in 2014, I mainly focused on analyzing geolocated data. Then I opened up to a larger field of data by training myself online. “His work as a data scientist led him to play the role of computer scientist, mathematician, statistician ...

'The smallest company has to use data'

'We help companies make their decision by creating algorithms and extracting statistics,' summarizes Renaud Colin. “This can be used for activity management, as in the case of a company that wants to deepen its customer knowledge or analyze the typology of markets. In industry we can also identify this or that variable and explain the rejection rate when making a part on a line. ''

Its services also make it possible to create predictive models, “for example for the number of customers lost and gained by subscribing to a service. »There are many applications and affects all trades. “In the HR department, we can also define a fluctuation rate based on certain parameters. ''

Closer to the region, there are also engineering degrees with a big data specialization such as the IAMD: Engineering and Applications of Masses of Data (at Télécom Nancy). Bootcamps data can also be accessed as part of a retraining course. These short and intensive training courses usually last no longer than a year. The salary of a beginner varies between 35,000 and 40,000 euros and for an experienced professional can be between 60,000 and 70,000 euros.
