Gravi

Hi! I'm Pietro.

I make games, apps and the servers behind them. Computer Science student at EPFL, I build full-stack systems end to end: a multiplayer game with its own backend, a school app used every day, and the odd thing soldered onto an Arduino.

Main projects

Junked!

Multiplayer game · in development

An online party shooter where everything in the house is a weapon. Grab it, throw it, junk 'em. Unity client, dedicated server, accounts and store on my own VPS.

Messagyre

School app · 2024 — 2026

Born as an informal chat for the Gymnase de Renens, grown into a full digital school diary: messages, grades, homework and news. On the App Store and Google Play, in Switzerland.
