About Victor

Senior Analytics Engineer | Data Analyst

Expert en transformation des données en actifs stratégiques pour les organisations, je conçois et implémente des architectures data modernes, intégrées et évolutives.

Mon expertise
Je combine data engineering, analytics et data science appliquée pour créer des solutions concrètes à fort impact business :
  • Architectures data modernes : Conception de pipelines robustes et évolutifs sur AWS, GCP et Azure en utilisant des frameworks comme dbt, Airflow et les technologies cloud natives.
  • Modélisation analytique avancée : Création de structures de données optimisées (Lakehouse, approche Bronze/Silver/Gold) sur Snowflake, BigQuery, Fabric ou DuckDB pour garantir performances et fiabilité.
  • Insights métier actionnables : Transformation de données complexes en visualisations percutantes et KPIs stratégiques via Power BI, Looker ou Tableau.
  • Industrialisation de l'intelligence data : Développement et déploiement de modèles prédictifs intégrés aux workflows métier pour la segmentation, le forecast, la détection d'anomalies et l'optimisation.
Ma valeur ajoutée
Mes interventions se distinguent par :
  • Une compréhension rapide des enjeux métier pour orienter les solutions techniques
  • L'automatisation systématique des processus pour garantir fiabilité et scalabilité
  • Une approche DevOps/DataOps avec versioning, CI/CD et documentation
  • La capacité à traduire des besoins métier complexes en architectures data cohérentes
Je peux intervenir aussi bien dans des environnements data matures que sur des projets nécessitant de poser les fondations d'une infrastructure analytique.

Mon objectif : transformer vos données en levier de performance mesurable, avec des solutions adaptées à vos enjeux spécifiques et une mise en œuvre rapide et efficace.
