About
Software Engineer with 12 years of experience across healthcare, fintech, insurance, and enterprise. I specialize in full-stack development: designing APIs with Node.js and NestJS, building React and Next.js frontends, and working with cloud infrastructure on AWS and GCP.
Currently at Nolte, I work with US-based startups to build their core products end-to-end. I collaborate closely with cross-functional teams to align technical implementation with product and business goals. Bilingual in English and Spanish.
