Back to original languageAbout Valentin
Expert Data for over 6 years, passionate about the field, I have led and executed numerous Data projects in the aeronautics and logistics sectors (DAHER). I work on both the Design part (creating an architecture that considers technical and budgetary constraints) and the Build part (development, testing). With over 4 years of experience and certified on Azure, I am able to support you on large-scale projects.
I had the opportunity to be the technical leader of a Big Data project for analyzing flight data at DAHER (TBM Analytics), which was awarded the Big Data Paris 2019 Innovation Trophy. This project led to a smartphone application that you can find on mobile stores: Me&MyTBM.
