About Christopher

Lauréat de la compétition de datascience FINTOC (compréhension automatique de la structure d'un document) en 2021
Auteur du livre "Deep learning with Theano" en 2017
15 000 visiteurs uniques sur christopher5106 github
Diplômé du master "mathématiques, vision par ordinateur et apprentissage informatique" (MVA) de l'ENS Cachan en 4e année de l'Ecole Polytechnique

J'ai travaillé sur de nombreux projets et POC, à partir de mon expertise en vision par ordinateur au départ (détection de piétons, analyse automatique des factures, des documents d'identité, des plaques d'immatriculations, des contrefaçons, recherche visuelle, géolocalisation par l'image, ...) puis en langage naturel (analyse automatique des documents, des contrats, classification des lignes de dépenses, chatbots, déduplication de bases de données d'entités légales ou produits, ...).

Je suis à votre disposition pour vous accompagner, ou bien en tant que développeur Python/Machine Learning/IA/data science/data-engineer, ou bien en phase amont de vos projets pour discuter de la faisabilité: rien ne vaut une bonne étude avant de se lancer.
