Freelancer profile translated to English.

Description

Coming from business intelligence (BI development then consulting), I have progressively expanded my scope to data governance and architecture. 20 years of experience, from on-premise legacy to cloud platforms (Snowflake, BigQuery, dbt).

End-to-end governance: business scoping, prioritization/roadmap, target architecture, delivery, production deployment and run (SLA/SLO), change management.

Positioning: bridging the gap between business objectives, IT constraints, and data execution, while staying close to the ground to validate technical choices before industrialization.

–Quality: testing strategy and GA/Piano reconciliation (gap < 7% validated by business). Metadata governance via Collibra. Privacy scoping: normalization of identifier protection practices and validation of compliance rules before industrialization.
–FinOps: cost stabilization at approx. 0.53 USD / 1M events; reduction of BigQuery costs by > 30% (query optimizations, standardization).
–Industrialization: prototyping (dbt, Kestra, Terraform, GitHub Actions), then handover for production industrialization. Onboarding new sites, tracking conventions, runbooks.
–Complementary projects: provision of Sales KPIs (in-store); migration of geolocation data to improve web revenue distribution between stores.
