I build software and talk about it out loud.

Turn it: the site goes from quiet to loud.

Portrait of Roberto Gayol

Solid architecture, explained out loud.

For 8+ years I've built frontends for banking, finance and industry: Angular architectures from scratch, legacy migrations and teams that ship without surprises.

On Volumen Arriba I share what I build, what works and what doesn't. With Código Nebula I help businesses automate with AI what they still do by hand.
