Hi, I'm Julio 👋
Full stack developer. I like owning the whole project: designing the database, writing the API, building the front end and shipping it.

About

My main project is Afetum, a SaaS by Skurt Brasil where I work as a full stack developer.

I also work full stack on Gestiona Pública, a large platform for handling documents and procedures with Spain's public administration: clients, case files, deadlines, documents and automated filings with the AEAT, the Spanish Tax Agency.

Besides that, I build projects for clients, like Next.js websites for businesses in Spain and Andorra and the RZ Importados online store.

I take on projects in Portuguese, Spanish and English.
