What I'm looking for

I'm looking to build scalable SaaS and web applications where I can contribute across React frontends, Node.js backends, testing, deployment automation, accessibility, and reliable user experiences.

I've delivered end-to-end web applications for Lean Tech, Cibernética de México, and freelance clients, using React.js, Node.js, TypeScript, and scalable backend services.

At Lean Tech, I built reusable UI components from Figma designs, automated Docker and GitHub Actions deployments, and reduced release times by 30%. I also developed REST APIs, database integrations, geolocation features, and maintainable state management with Redux, Context API, and React Query.

I've built healthcare SaaS modules compliant with FHIR, secure microservices with JWT authentication, and flexible authorization with Casbin.js. I focus on accessible, responsive React experiences, reliable testing, and practical AI-assisted development workflows.
