Back to original languageAbout Ahmed
I am a data engineer with over 9 years of experience in designing, industrializing, and optimizing data solutions. Passionate about solving data-driven problems, I have developed scalable pipelines, improved data quality and governance, and created dashboards with Power BI and Streamlit. My expertise covers Azure (Data Factory, Synapse), Databricks, DBT, Snowflake, as well as Python and Spark.
Throughout my career, I have held leadership roles—notably overseeing the data strategy at TELMMA—while also undertaking operational engineering missions at PwC and Les Mousquetaires. Certified in Databricks, Azure Data Engineering, and Microsoft Fabric, I am fluent in French, Arabic, and English.
My true strength lies in the diversity of architectures, technologies, and business environments I have encountered. This variety gives me perspective to design high-performing, robust solutions tailored to the specific constraints of each organization. Having worked in numerous fields, I have developed a cross-functional vision that allows me to anticipate challenges, ensure system reliability, and optimize end-to-end performance.
