Slimane Lakehal

Analytics engineer freelance, I help data teams build reliable pipelines, clear models, and actionable dashboards — from ingestion to visualization.

My playground: the modern data stack. I work daily with Python, SQL, dbt, BigQuery, and Power BI, both for modeling complex data and for automating robust ETL/ELT flows.

What sets me apart? A dual grounding in field experience and pedagogy: I am also a data trainer at Le Wagon, which forces me to clearly explain every technical choice — your teams understand what we are building together, not just what it produces.

What I handle:

- dbt modeling (staging / intermediate / marts layers, tests, documentation)

- Python pipelines for data ingestion and transformation

- Decision-oriented Power BI or Looker Studio dashboards

- REST API development (Fastapi)

- Audit and restructuring of existing data projects

- Support and skill development for your teams

My background — pharmacist, retail manager, then data — taught me to read a business need before touching code. I don't deliver pipelines, I deliver useful value.
