What I'm looking for

I seek a role that fosters a data-driven culture, encourages collaboration, and offers opportunities for professional growth.

As a Senior Data Engineer at deX, I contribute to planning and building the core product alongside software engineers. My role involves providing technical feedback, creating guidelines for implementation, and supporting clients to ensure seamless integration with our platform. I manage all aspects of data engineering and lead a team of Data Scientists and Data Analysts, ensuring adherence to best practices in data handling.

My career began in 2016 as a database administrator, and since then, I have evolved through various data-oriented roles, ultimately specializing in data engineering. I have successfully handled platforms processing over 100 million daily records, developed flexible Spark frameworks for data ingestion, and integrated multiple services to enhance platform stability and observability.

My career goal is to simplify data-informed decision-making for both technical and non-technical colleagues. I actively promote a data culture within organizations and strive to create self-service data solutions that empower teams to leverage data effectively.
