What I'm looking for

I'm looking to build impactful web and digital products where I can contribute across full-stack development, product execution, applied AI, automation, data analysis, and technical project leadership.

I'm building Ceibix as its founder, CEO, and lead developer, shaping product strategy, architecture, prototypes, and technical validation while using AI workflows to accelerate development and documentation.

Through TuWebXpress, I design and deliver responsive business websites with clear visual experiences, using Figma, HTML, CSS, JavaScript, Vercel, and modern web-publishing practices. I've also developed more than 10 web applications and prototypes using Angular, Node.js, PHP, MySQL, Firebase, and Supabase.

My work includes GIPPAL, an institutional platform for the University of Cordoba, and Opportunity Joven, a municipal employability platform focused on accessible youth employment. I contribute across functional design, UX, web architecture, dashboards, CRUD flows, integrations, and frontend-backend delivery.

As a final-semester Systems Engineering student, I combine web development with project leadership, applied AI, data analysis, and technology entrepreneurship. I've also delivered training on AI applications in research and teaching for university faculty and researchers.
