What I'm looking for

I am looking for a role that fosters innovation and collaboration, with opportunities for career growth.

I am a data-driven professional with over 15 years of experience in data engineering and analytics. My career has been dedicated to designing and executing ETL processes that support management reporting and advanced statistical modeling. I have a proven track record of conducting in-depth data analysis and customer profiling, which has significantly enhanced business strategies and driven informed decision-making.

Currently, I serve as the Lead Data Engineer at Ximple, where I am responsible for establishing a modern data infrastructure from the ground up. My key achievements include architecting robust ETL pipelines using AWS services and implementing data governance standards that enhance compliance and data discoverability. My previous roles at McKinsey & Company and Vivo have equipped me with a diverse skill set in managing cloud environments and developing automated reporting solutions that deliver real-time insights.
