Freelancer profile translated to English.

Description

Hello!

**Junior Data Analyst / Data Scientist**, specializing in **Python, SQL & BI**, I support teams that are starting or structuring their data initiatives: cleaning data, building relevant KPIs, and delivering clear dashboards rather than incomprehensible "black box" models.

After 4 years of experience (Orange, CREM, MTN) and several personal projects (dashboards, workflow automation, predictive model POCs), I position myself as an operational profile, autonomous on concrete topics butcapable of simply explaining what I do and why.

**What I can do for you**:

Improve the quality of your data (SQL / Excel / Python) and prepare a clean, documented dataset.
Create or improve your performance reporting (Power BI / Tableau / Streamlit): activity tracking, sales, customer service, operations.
Develop ad hoc analyses and "reasonable" ML models (segmentation, simple scoring, anomaly detection) when there is a real business interest.

**My added value**: a junior profile, therefore flexible and approachable, but already accustomed to working with business teams and delivering concrete deliverables (dashboards, reusable scripts, mini-apps) with skills transfer so that you remain autonomous afterward.
