Over Ahmed

Lead Data Engineer | Architecte Data & Plateformes Analytics Scalables

J’accompagne les équipes produit, data et engineering dans la conception, la structuration et la mise à l’échelle de plateformes data modernes, fiables et orientées business.

Avec plus de 7 ans d’expérience sur des environnements cloud data à fort volume, je travaille principalement sur des sujets où la qualité des données, la performance et la maintenabilité sont critiques :

• Architecture data (batch & streaming)
• Pipelines temps réel (Dataflow, Pub/Sub, Beam)
• Data warehouses & lakes (BigQuery, GCS)
• Orchestration & fiabilité (Airflow / Cloud Composer, monitoring, alerting)
• Gouvernance, tracking événementiel, conformité (GDPR)

J’interviens souvent comme référent technique ou lead, en lien direct avec :
• les équipes produit
• les développeurs backend / frontend
• les équipes analytics, marketing ou CRM

J’apprécie particulièrement les missions où il faut :
• reprendre une plateforme existante et la fiabiliser
• concevoir une architecture scalable from scratch
• structurer de bonnes pratiques data au sein d’une équipe

Objectif : construire des systèmes data robustes, compréhensibles et exploitables sur le long terme

Disponible pour des missions Lead Data Engineer / Senior Data Engineer, en environnement cloud, avec un fort enjeu produit ou business.
