About Júlia

I entered the world of data about 7 years ago. Due to the needs of various projects I had at work at the time, I started working with Power BI Desktop on a self-taught basis. This knowledge and experience have led me to my current position.

Currently, I work as a Data Engineer, processing data and presenting it in reports. I build everything from integration processes to visualizations. I have worked with clients such as Repsol, Inditex, and Planeta, among many others.

Proyecto e Arquitectura en Cloud y generación de dashboard en Power BI - Apache

Less than 1 year project

Reviewed on 12/17/2025

Julia and her team (Ana and Javier) executed the project with a high technical level and architectural rigor. They defined and implemented the GCP architecture solidly, with a special focus on scalability and best practices, and developed the Power BI dashboards perfectly aligned with business requirements. Communication with them was always clear and fast, with a good ability to anticipate risks and propose solutions. They met deadlines and deliverables as agreed. They are a highly recommended team for data, cloud, and data visualization projects in both Power BI and Looker. We will continue working with them on future projects, without a doubt!
