Data Analyst focused on automation and decision-ready dashboards using Power BI, SQL, R, and DAX.
FranceWhat I'm looking for
I’m a Data Analyst with experience building advanced Power BI dashboards and data models to support operational and decision-making monitoring. In a fixed-term role, I optimized SQL query deployment for financial audits, uncovering over 10,000 anomalies, and I automated reporting with R to move from a week-long process to a single click.
I also bring a business analysis mindset from roles in requirement gathering and stakeholder alignment, standardizing client needs and turning multi-actor requests into actionable technical specifications. I’m motivated by clear, reliable data analysis—data cleaning, visualization, audit, and impact measurement—so stakeholders can make strategic and operational decisions with confidence.
