Marco Sebastián Ortega Molina

Information Systems Engineering student at Universidad de Sonora (UNISON), 5th semester. I build full-stack web and mobile applications with real AI integration — not just API wrappers, but thoughtful implementations that solve actual problems. From medication management with AI health assistants to business automation pipelines, I ship software that works.

Let's build
something real.

Open to remote opportunities in AI training, data annotation, RLHF, and full-stack development. Let's talk.
