About Yann

== Available remotely only, part-time ==

Consultant for 20 years (3/4 of which self-employed), I work in all areas of digital with a multi-skilled profile (Web, Mobility, Big Data, IoT).

Recent years could be summarized as 40% project management/coordination (Agile Scrum/Traditional), 40% expertise/development (fullstack), and 20% training, depending on the assignments.

I have had the opportunity to work on projects for numerous clients, from "start-ups" to large corporations: Total, Engie, Ymagis, Carrefour, Groupement des Mousquetaires, Makioly, Renault, Crédit Agricole, LCL, France Télévisions, PMU, Oxylane, Learning Tree International, ESAIP, Ministry of Economy and Finance, Orange.

I look forward to participating in yours!
