Do you want to modernize your data platform or industrialize your pipelines on AWS? You've come to the right place.
Data Engineer with 10 years of experience, I help data teams industrialize their pipelines and centralize their business data using AWS, Databricks, and PySpark. I design Medallion architectures (Bronze/Silver/Gold), scalable PySpark pipelines, and complex multi-source integrations. AWS Solutions Architect certified.
At Cellnex, I unified 3 heterogeneous systems (AGORA, Maximo, COS) into a single data platform, with self-service Power BI reporting and end-to-end monitoring. Before that, I deployed over 180 sites and managed over 1000 projects at Bouygues Telecom.
I work in short sprints with regular deliveries, proactive communication, and careful documentation. I adapt to business constraints as well as technical constraints.
Contact me to discuss your project, I respond in less than 1 hour.
