Full stack web developer · Network administrator

Hi, I'm Arnaldo Espinoza

I build websites and web applications with Next.js, Nest.js and PostgreSQL, backed by more than 20 years of experience in technical support, networking and servers.

About Me

From networks and servers to full stack development

I started out in technical support and network and server administration, configuring Linux servers, routers and switches. Today I focus on full stack web development: React and Next.js with TypeScript and Tailwind CSS on the frontend; Node.js, Nest.js, MySQL and PostgreSQL on the backend. I'm passionate about technology, enjoy teamwork and I'm always learning.
