    Frontend Developer · Hirint ↗

    I develop and scale the platform on a modern stack, after helping migrate the legacy architecture to Next.js and TypeScript.

    • Designed and shipped the Valoraciones (assessments) feature end to end — from the data model and Laravel logic to the final UI.
    • I maintain 15+ evaluation report types (web and PDF) with reusable components; optimized SQL queries for bulk exports.

#about

A bit about me.

Hi! I'm Mónica. A full-stack developer with 4+ years building modern web solutions. My strength is the React ecosystem —Next.js and TypeScript— but I move comfortably across the backend with Laravel, so I understand the product end to end.

I love turning manual processes into efficient digital tools. Before becoming a dev I was a STEAM educator, which gave me clear communication, teamwork and creative problem-solving. I always look to add value beyond the code.
