Computer Systems Engineer | Business Intelligence | Data Analyst | Business Administration

I design and develop visually stunning, user-centered interfaces that transform complex data into intuitive and actionable insights, delivering engaging digital experiences as a front-end developer.

About

I leverage my data analysis, operational management, and learning development expertise to drive continuous improvement across various sectors. By using data-driven insights, I enhance financial outcomes, care quality, and operational business efficiency. Fast-forward to today, and I’ve had the privilege of building software for an Tecnical Academy, of a big company, a credits and loans system for a start-up, a point sales system for huge corporation, and a digital product studio.

My ability to apply analytics in marketing initiatives leads to informed decision-making, improved customer satisfaction, and successful campaigns.

At the moment I enjoy a lot being an instructor of SQL & Databases, Django, API's, and JavaScript at Foundever.

As a front-end developer, I create responsive and user-friendly interfaces that facilitate access to critical data, further enhancing user engagement and satisfaction. Additionally, my systems oversight and data management skills ensure smooth operations in call centers and technical environments, supporting strategic decisions.

When I’m not at the computer, I’m playing Padel, reading, hanging out with my children, do gumplas, play with my cat, Or fighting with kings in castles to be the true Elden Lord.
