Freelancer profile translated to English.

Description

I am Yassine, Analytics Engineer & BI Lead with over 8 years of experience. I help data and business teams transform their raw data into reliable, readable, and actionable reporting – whether at a major company like Cartier or Sonepar, or in a fast-growing scale-up like Exotec.

My playground: the Modern Data Stack (dbt, BigQuery, Power BI, Looker) combined with a real understanding of business needs – finance, marketing, sales, logistics, HR.

Concretely, I am involved in:

🔍 Audit and scoping — understanding where your data is hindering decision-making

🧱 Modeling — building robust and maintainable dbt pipelines

📊 Visualization — Power BI or Looker dashboards that your teams truly adopt

⚙️ Governance — standardizing, documenting, and industrializing your BI practices

🎓 Training — making your teams autonomous on their data tools

What sets me apart? I speak as fluently with developers as with business directors. I don't just deliver a report — I ensure it's used.

📩 Do you have a data or BI project? Let's connect, even for 30 minutes to clarify your needs.

🚀 Results achieved

◦ Reliable and industrialized reporting

◦ Faster and better-driven decisions

◦ Reduction of BI technical debt
