Lagune Market est une place de marché en ligne inventée, basée à Abidjan, en Côte d'Ivoire, avec des prix en FCFA et des paiements par mobile money, carte ou à la livraison. Tous les clients, commandes et documents sont inventés.

Dossier	Rôle	Fichiers	Devoir
data-scientist/	Data Scientist	orders.csv, customers.csv, products.csv	Charger et relier les fichiers, faire des graphiques et partager vos constats
ml-engineer/	Ingénieur en apprentissage automatique	deliveries_train.csv, deliveries_test.csv	Prédire si une commande arrive en retard (late)
ai-engineer/	Ingénieur IA	docs/en, docs/fr (règles et rapports mensuels), questions.csv	Un assistant conversationnel qui répond aux questions de l'équipe sur l'entreprise, avec ses sources
project-lead/	Chef de projet	project_brief_en.md, project_brief_fr.md	Un plan sur 12 semaines : étapes clés, qui fait quoi, 3 principaux risques

Les fichiers viennent d'un export Excel au format français : il faut donc faire attention en les chargeant. Les réponses ne sont pas dans ce dépôt.

Le schéma « How the tables join » ci-dessus montre comment relier les tables : orders.customer_id vers customers, et orders.product_id vers products. Chaque dossier contient un README.md avec les consignes complètes.
