Acerca de Juan Carlos

Computer Engineer (URV) and fullstack developer. I build web applications from scratch — frontend, backend, and deployment. My stack: Next.js, React, TypeScript, Node.js, .NET, and AWS.

I've built two complete products independently: a B2B SaaS platform (AetherSec) and an AI-powered voice assistant for appointment management. I also have professional experience as a fullstack developer intern at 4Link working with .NET, Entity Framework Core, and React.

3 hackathon awards: 1st in Cybersecurity CTF, 2nd in Cloud Computing, 4th at Talent Arena MWC.

What I can help you with: MVPs and prototypes built fast, internal tools and dashboards, API integrations and automations, AI-powered solutions (voice agents, chatbots, workflow automation).

Based in Tarragona, available for remote work across Spain and Europe.
