About
Developer in all forms of data processing: from visualisation to the creation of processing processes through to machine learning algorithms (AI).
I've been working as a independent data engineer since 2018 for consulting firms
, large companies, startups and SMEs.
I support my clients
on their digital transformation trajectory gthanks to the diversity of my skills acquired over the course of my assignments in,
data processing (ETL), setting up data storage architecture de
on the Cloud and all types of data enhancement (visualisation, machine learning algorithms, automation).
As I'm heavily involved, I keep a close eye on the level of performance expected by my clients.
I love the variety of encounters and challenges, as well as taking part in new technological challenges that have a positive impact. Thanks to my entrepreneurial activity and some of my clients, I've been able to help promote accessibility and digital access for people with disabilities.
I'm based in Montpellier, South of France, but my work takes me to Paris on a regular basis and I work most of the time remotely. I'm always on the lookout for new technologies and topics, which I share via my Blog.

CTO à Onefinestay (Groupe Accor)
Florian has been working with us for 2 years. Initially, it was for a 6 months contract, consisting in migrating our data pipelines to work with the new systems we were implementing at time. Florian did very well, understood the business concepts quickly, our tech environment as well, meaning that the job was achieved in time, although it was not very easy with the amount of legacy transformation queries we had at the time. Since everything was going well, and that we had growing internal needs, I decided to continue working with Florian. He continued to clean up our legacy systems, and he migrated our whole ELT processes into DBT. He prepared training slides, and trained the teams internally. The job was achieved in less than 2 months. This greatly improved our ways of working, thus the internal teams satisfaction. Florian also worked on pushing our financial data coming from our backoffices to NetSuite. This was a very complex project, with multiple NetSuite customization needed. Florian never abandoned, even though it was really difficult to get all the required information sometimes. Florian worked on many other structural and strategic projects during these 2 years, and he never let me down. The only reason we had to stop working together is because we wanted to internalize the position, but Florian wanted to remain as a contractor, which I can fully understand. Florian is a true gem, he can work on very complex projects, and go to the bottom of them, without any doubts. He is also a very nice person, which is always a nice addition :) We will miss him, for sure.

En plus d'un relationnel très agréable, Florian est consciencieux, rigoureux, à l'écoute tout en étant force de proposition. Florian a très vite compris mes besoins, à savoir la mise en place d'une base de données regroupant certaines données publiques que je souhaitais exploiter sur Tableau software. Il a réalisé plusieurs scripts permettant d'automatiser la mise à jour quotidienne de la base de données et fait le nécessaire pour installer ensuite celle-ci sur un serveur. Il m'a épaulée dans le choix d'une formule d'hébergement pour le serveur. Le travail rendu est très propre et bien documenté. Un vrai talent que je recommande totalement.
