Hi, I’m Julián Quintana, a Full Stack Developer and Computer Science graduate with hands-on experience across the MERN/MEAN stack (Node, MongoDB, Express, React/Angular, and Next.js). I’m passionate about delivering responsive UI/UX and robust backend systems, and I excel at turning complex user stories into clean, scalable features. I also have foundational exposure to AI/ML, including custom detection models (YOLO) and character recognition pipelines, which fuels my curiosity for building intelligent, data-driven applications. I enjoy collaborating with product teams to refine requirements, translate them into actionable technical specs, and ship high-quality software. I’m committed to continuous learning, building accessible interfaces, and creating robust solutions that scale with user needs.
