Back to original languageAbout Sofiane
Freelance Data Analyst with experience in startup environments and a dual business and technical background.
I have independently managed the entire data scope for a mobile application: data structuring on Snowflake, building control dashboards on Power BI, and product analyses that led to concrete decisions, including a 12% increase in onboarding completion rate within two weeks.
Data Engineer Certification co-certified by Mines Paris completed in February 2026, giving me an end-to-end view of the data pipeline, from ingestion to delivery.
I quickly adopt new tools and environments. I translate data into actionable insights for non-technical stakeholders. Immediately available in the Île-de-France region.
