Gian Lopez

AI Engineer & Frontend Developer

Building intelligent, user-centred web applications with React, Next.js, and AI — grounded in real UX research.

About Me

I build AI-powered web applications with React and Next.js, bringing a deep background in UX research and healthcare to every product I work on.

My case study HealthBridge showcases my AI engineering skills—building a symptom triage assistant powered by RAG, tool use, and multi-step reasoning with Next.js. The Coaching App demonstrates full-stack capability, from user personas through to a working production application.

I bring both sides together: the technical skills to build intelligent features with LLMs and modern frameworks, and the design thinking to make sure those features actually serve real users. I work in React, Next.js, TypeScript, and Tailwind CSS to turn research-driven designs into real, responsive products.
