About

More About Me.

I studied Graphic Design at FAD, UNAM and transitioned into software development through hands-on project work.

Full-Stack Developer with a proven track record delivering robust solutions for leading global industries. My expertise spans the entire software development lifecycle — from designing modern front-end interfaces to engineering scalable back-end systems and microservices.

I am currently focused on Generative AI, working on practical implementations using Prompt Engineering, RAG (Retrieval-Augmented Generation), and model fine-tuning. I leverage cutting-edge AI tools — including Claude and the Anthropic ecosystem — to solve complex problems and drive innovation for international clients.

Services

What I Do.

I build scalable web applications and GenAI-powered solutions, covering the full stack — from modern React/Next.js frontends to Python and Node.js backends — and integrating AI capabilities like RAG and prompt engineering into real-world products.

  • Soft Skills

    I have a lot of experience working on projects, for that reason I have strong communication skills and kind of those are required to communicate with teams, project managers and product owners.

  • Full-Stack Development

    I build end-to-end solutions across the stack. On the frontend: React.js, Next.js, Vue.js, TypeScript, Tailwind CSS. On the backend: Python (FastAPI), Node.js, Spring Boot, RESTful APIs, and microservices architecture.

  • Generative AI & Innovation

    I implement GenAI solutions using Prompt Engineering, RAG (Retrieval-Augmented Generation), and fine-tuning. I work with tools like Claude (Anthropic), GCP AI services, and Azure AI — turning cutting-edge AI capabilities into production-ready features.
