About Alex

Passionate about data exploration and its ability to transform businesses, I specialize in data analysis, visualization, and artificial intelligence. My experience as a Data Analyst at Bouygues Telecom and my previous roles as a Data Consultant and Data Scientist have allowed me to develop strong expertise in manipulating, analyzing, and visualizing large datasets using cutting-edge tools such as PySpark, Tableau, Python, SQL, and various cloud technologies (Amazon S3, Google Cloud Platform, Microsoft Azure).

My analytical approach and ability to generate relevant datasets enable me to effectively prepare data for complex analyses, supporting Data Scientists and contributing to ambitious Big Data projects. I am proficient in comparing different data sources to extract valuable insights, and I excel at creating impactful visualizations with Tableau, as well as commented analyses with Excel, to inform strategic decision-making.

My experience at Orange Business, happn, and in fraud detection projects with AWS demonstrates my ability to address diverse analytical challenges, from forecasting reliability to fraud detection and user behavior studies. This variety of projects has allowed me to develop extensive technical expertise, including the use of advanced technologies such as Elasticsearch, Git, TensorFlow, as well as skills in ETL and machine learning.

I am convinced that my passion for data, combined with my experience and technical skills, will enable me to bring significant added value to any organization seeking to leverage its data to accelerate growth and strengthen its competitive advantage.
