I am a senior Data consultant specializing in Business Intelligence within Microsoft BI (MSBI) solutions — SQL Server, SSIS, SSAS, SSRS — as well as Power BI, ODI, Semarchy xDI/xDM, and Business Objects.
I help organizations transform their data into levers for operational and strategic performance by offering integration, modeling, and decision-support solutions tailored to their business needs. Leveraging solid technical expertise and a deep understanding of business challenges, I enable my clients to make their data reliable, automate their BI processes, and accelerate their decision-making with dashboards and architectures that deliver measurable value quickly.
Result: reliable and visible indicators, increased responsiveness of business teams, and improved competitiveness in a demanding digital environment.
If you are looking to fully leverage your data to optimize costs, improve performance, or structure your BI strategy, I offer a quick diagnostic of your decision-support information system to identify immediate possible gains.
