Description

Senior Data Data Analyst / Analytics Engineer with over 6 years of experience.

I work across the entire analytics chain:

Centralization of sources and data orchestration
Data organization and implementation of reliable indicators
Data visualization and BI reporting used daily by business teams

My core expertise lies in:

Structuring cloud data warehouses (BigQuery)
Analytical data modeling (Kimball, star schema, marts)
Implementing robust and maintainable SQL transformations (dbt)
Reliability and consistency of metrics (SaaS, product, finance)
Providing clear KPIs and dashboards (Metabase, Looker, Power BI, Tableau)
Advanced data analysis (Python)
Developing POCs and data applications (Streamlit, Plotly)

I master Python for automation and data analysis, particularly with pandas and NumPy for dataset exploration and preparation. I also use orchestration tools like Airflow to design and operate reliable data pipelines.

I work with startups and scale-ups, as well as more mature organizations. I collaborate directly with product, marketing, finance, and management teams to ensure data reliability and improve decision-making.
