Back to original languageAbout Tamsir
I am a financial performance consultant and Data Analyst, with over 8 years of experience in finance, management control, and audit, particularly in structured environments (Mazars, public sector, IT/ERP).
I assist companies in analyzing and steering their performance by transforming their data (sales, purchases, finance) into clear and actionable indicators.
Thanks to a dual business (finance/accounting) and technical (SQL, Power BI, Python) expertise, I design dashboards and decision-support tools to optimize profitability, cost monitoring, and business management.
I primarily intervene in:
- Power BI dashboard creation
- Financial data analysis
- Process and reporting optimization
- Data structuring and modeling (ERP / SAP)
My goal: to help companies better understand their figures and make more effective decisions.
