About Youssef
I’m a freelance Business Intelligence consultant with over 14 years of experience helping companies turn complex data into clear, actionable insights. I design and deliver end-to-end BI solutions, with strong expertise in Power BI — from advanced data modeling (DAX, M) to high-performance dashboards built for business users.
What I help you with:
- Power BI development: data modeling, DAX optimization, interactive dashboards, row-level security, and performance tuning
- Cloud data pipelines: ETL/ELT design and orchestration with Informatica IICS
- Modern data platforms: Snowflake data warehousing, ELT processing, BI integration
- BI industrialization: CI/CD, GitHub versioning, automated deployments, best practices
How I work:
I integrate easily into existing teams and Agile/Scrum environments. I work closely with stakeholders, data teams, and developers to deliver reliable, scalable solutions — from raw data ingestion to executive-ready reports and business insights.
Availability:
Open to short- or long-term freelance missions to modernize your data stack, improve reporting performance, and maximize the value of your data.
