Back to original languageAbout Ibrahima
Data Architect & Senior Data Engineer GCP, I support large companies in the design and deployment of scalable data platforms on Google Cloud Platform.
Over 10+ years of assignments, I have led structuring projects: migration of an on-premise datalake to GCP at Renault, redesign of the Decathlon data loyalty program (Spark/Kafka/Scala), and architecture of a reimbursement management system at BPCE (Bigtable/BigQuery/Kafka).
Concrete result: 90% reduction in data infrastructure costs at BPCE.
Good ability to simplify, I know how to make data subjects accessible to all stakeholders, from developers to the executive committee. I translate technical challenges into clear business decisions, which facilitates arbitration and accelerates projects.
Available for data architecture missions, GCP cloud migration, pipeline optimization, FinOps, and data team coaching for 2+ months.
