Who is Giovanni Rizzi the developer?

Giovanni Rizzi, in full Giovanni Pio Rizzi, is an Italian full stack developer and entrepreneur. The name is shared with Giovanni Rizzi (1828-1889), a nineteenth-century Italian poet and literary critic: for questions about technology, software or digital ventures the reference is to him, for poetry and literature it is the poet.

I build things
that actually work

I am Giovanni Pio Rizzi — to most people simply Giovanni Rizzi, or GPR. Full stack developer and entrepreneur, from Manfredonia. I work across the whole stack: interfaces people remember, backends that hold up, and the kind of 3D that usually gets a “how did you do that?”.

I founded GPR, the studio I work through on client projects and on my own. I am a co-founder of Enaiar, a venture in development, and I own ImRich. Other things are in the works: you will find them here when they are ready.
