Leafranger
Mirko Cisternino
I build Discord bots, automations and API integrations: software that does the repetitive work so you don't have to.
Recent work
Most of these began as tools I wanted for myself. Each one has its full story, including how it ended.

Making a Roblox game?
Since 2020 I've made sound effects, interfaces, scripts and models for Roblox games. Studios and commissioners have their own page, with every asset to see and hear.
Open source, free for everyone
Some of what I build goes to the community: free tools, released as open source. If one of them helped you, a donation helps me keep releasing them.

Got something that should run on its own?
Tell me what it should do, where it runs and when you need it.
I work in Italian and English, and small jobs are welcome.
