Hi, I'm Mariano 👋

I'm a CS student who loves building open-source tools and solving backend problems. The projects I built started as personal needs. I lean heavily towards efficiency and user privacy, whether I'm writing a Rust scraper or shipping an offline-first app.

⚙️ What I Do

I strongly prefer backend and systems programming over frontend design. In the past, I used to make indie games (especially in GDScript) and self-host a lot of my own services.

🎧 Beyond Code

I read mostly non-fiction (although I enjoy some fiction too), and I listen to a lot of music. I'm also a big fan of F-Droid and the open-source community.

Things I built because I needed them

From privacy-first expense trackers to mapping Italian dialects.

  • Denaro

    Denaro is a privacy-first personal finance app built with Expo and React Native. It works entirely offline: organize your money into customizable "buckets", record incomes and expenses, transfer funds between buckets, and automate recurring transactions — all stored locally in an encrypted database.

    • Expo
    • React Native
    • Encrypted DB
  • Dialettario

    Dialettario is a collaborative dictionary of Italian dialects that allows you to discover, add, and consult local terms by region, province, and city.

    • T3
    • TypeScript
    • Next.js
    • Expo
  • NStates

    An Android client for NationStates built to provide a better native experience than the browser version.

    • Jetpack Compose
    • Kotlin
    • Android

🧠 My Approach

My Olympiad background taught me to care deeply about efficiency (my proudest moment was coding a segment tree with lazy propagation before ChatGPT existed). Lately, though, I use AI to help me ship faster so I can focus on solving real problems for real people.
