I'm Andrea Roversi, and I build web apps for the real world. From PWA business management tools to e-commerce with integrated payments and conversational AI — every project starts with a real problem.

Experience

I've spent years managing teams, so I know where processes grind to a halt, where tools break at the worst possible moment, and what people on the ground actually need. That perspective is why my apps get used.

What I like building

I wrote my first webpage in 1999, with FrontPage and a lot of curiosity. Self-taught first, then courses, then real-world demands — each phase shaped how I build things. My philosophy hasn't changed: code has to work. And it has to look good. Not one at the expense of the other.

Approach

I mainly work with Firebase, Netlify, and single-file HTML architectures — lightweight solutions, fast to deploy, and zero unnecessary dependencies.


Built applications

From business operations to e-commerce, from AI to entertainment — every project is a problem solved.
