Who I am

Developer &
Data Specialist

Hi, I'm Jose Zaldaña — a web and software developer with a passion for building clean, well-crafted digital products. I care deeply about code quality, user experience, and maintainable systems.

Beyond frontend and backend development, I specialize in data analytics and Business Intelligence — helping teams make sense of their data through dashboards, pipelines, and actionable reports.

Whether it's a full-stack web app or an end-to-end data solution, I bring the same attention to detail and drive to every project.
