Description

I help organizations transform complex data into powerful business insights through end-to-end Business Intelligence solutions. With a strong foundation in data engineering and analytics, I specialize in designing interactive Power BI dashboards, building robust data warehouse architectures, and automating workflows to drive smarter decision-making.

My added value lies in bridging the technical and business worlds—combining hands-on expertise in T-SQL, SSIS, SSAS, and Power BI with a strong understanding of business needs, especially in the pharmaceutical and telecom industries. I’ve led data integration projects using multiple databases (PostgreSQL, Oracle, Teradata), developed REST APIs, and streamlined operations using Power Automate.

Typical deliverables I handle include:

-Executive dashboards for sales performance and CRM insights

-Data migration and cleansing processes with PL/SQL and ETL pipelines

-Custom data cubes for high-performance analytics

-Automated reporting and notification systems

I’m passionate about data storytelling and always strive to make insights clear, actionable, and impactful for all stakeholders.
