Full-stack software engineer at Sembrando Sentido building AI document workflows and enterprise CRM platforms.

At Sembrando Sentido, I build full-stack application components and APIs that connect AI services with core product systems. I also prepare document datasets with OCR and layout-processing tools to support machine learning models.

As an independent consultant, I architected and deployed multi-tier CRM platforms for construction enterprises. My work spans database design, APIs, web interfaces, and mobile apps, including the Casabella CRM API and Angular frontend.

Earlier, I developed C# and WPF desktop tools at Variant and ASP.NET MVC applications at Technology Partners Puerto Rico. I’ve also worked on legacy-code reliability, integrations, and production support.
