Senior JavaScript engineer specialized in React and Node.js. I build complex frontend architectures — dynamic modules, graph-based UIs, design systems — with strong attention to performance, accessibility (WCAG), and DX. On the backend I work with GraphQL, REST, and serverless AWS. Lately I've been integrating AI into real products: assistants, content tools, and MCP server integrations.

Ingeniero senior de JavaScript especializado en React y Node.js. Construyo arquitecturas frontend complejas — módulos dinámicos, UIs basadas en grafos, design systems — con foco en performance, accesibilidad (WCAG) y DX. En backend trabajo con GraphQL, REST y AWS serverless. Últimamente integro IA en productos reales: asistentes, herramientas de contenido e integraciones con servidores MCP.

- Product mindset: collaborate closely with PM/Design, write clear tickets, ship small and safe increments
- Quality first: testing pyramid, observability, and CI/CD gates as non-negotiables
- Collaboration: code reviews with empathy, mentoring (ex-ReactJS mentor at Acamica), and documentation as a first-class citizen
