Back to original languageAbout Oussama
Data Analyst passionate with 8 years of experience in data management and analysis. I recently worked at Diptyque Paris, where I contributed to the management and support of the Data & CRM ecosystem. I designed high-performance data pipelines and automated critical workflows, thereby bringing efficiency and reliability to data processes.
Before this assignment, I worked as a System & Database Administrator (Power BI) for the Savencia group, where I honed my autonomy and developed strong expertise in complex problem-solving. This experience allowed me to cultivate a performance-driven, innovative, and collaborative approach.
With a strong adaptability and a taste for continuous learning, I am always ready to take on new challenges. If you need a Data Analytics & BI expert to support your projects and transform your data into strategic value, let's connect!
