About

I'm a Master's student in Computer Science and Engineering – Artificial Intelligence at Politecnico di Milano, after a 110/110 Bachelor's in Computer Engineering at Tor Vergata (Rome).

Alongside my studies I've spent five years as an IT consultant, running a small firm's entire IT environment: a Windows Server 2022 machine, Synology and QNAP NAS units with RAID-mirrored backups, user accounts and permissions, and a WireGuard VPN with NAT connecting three offices into a single private network.

Currently

• 📚 Working through deep learning, data mining and recommender systems
• 🤝 Member of Polimi Data Scientists, the data science student association at Politecnico di Milano
• 🔬 Heading toward an MSc thesis in applied AI and intelligent optimization
• 🛠️ Turning coursework into projects that actually run
• 🎶 Off-screen: organetto and chromatic accordion at Italian folk festivals

Selected Projects

Project	What it is	Stack
Sōkratēs	An AI tutor that answers questions with questions. A five-agent LangGraph system that turns a document into a Socratic coaching session: concept maps, spoken Feynman-style explanations graded on clarity, a delta score driving adaptive hints, and peer matching on complementary knowledge gaps. Built at GDG AI HACK 2026, 160 participants selected from 500+ applicants.	Python LangGraph LangChain Streamlit ElevenLabs
Milano Transit Simulator ▶ Live demo	Milan's entire public transport network, moving live on a map. ATM publishes no real-time vehicle positions, so a Python pipeline turns City of Milan open data into a deterministic synthetic timetable: 5 metro lines, 142 surface lines and 4,690 stops, holiday-aware service days, departure boards, vehicle tracking and a 60× time-travel mode. No backend, bilingual, WCAG AA, tested in CI and auto-deployed to GitHub Pages. Independent side project.	JavaScript Leaflet MapLibre GL Python GitHub Actions
Arabica Quality Prediction	Can you predict elite coffee before anyone tastes it? Classification on 1,311 CQI samples with only 8.2% positives, logistic regression, XGBoost and Random Forest, SMOTE-NC confined to training folds, and a target leak found via SHAP and removed.	Python scikit-learn XGBoost SHAP
Online Auction System	An eBay-style auction platform where the database itself enforces the rules. Taken from requirements through ER, logical and physical design: 19 stored procedures, 7 triggers guarding every bid (€0.50 increments, automatic counter-bids up to each bidder's ceiling, 3-level category tree), scheduled events that open and close auctions on time, isolation levels chosen per transaction, and role-based DB users granted only EXECUTE on their own procedures. Java MVC thin client over JDBC. Database Systems course, BSc.	SQL MariaDB Java JDBC Maven
NightPlan	Desktop app connecting users and event organisers: live chat, real-time notifications, and one MVC core serving both a JavaFX GUI and a CLI. Designed from UML with explicit design patterns.	Java JavaFX MySQL
¿WhoKnows?	Android trivia game with live questions from a public API, game history saved locally with Room, connectivity-aware gameplay and coroutine-based concurrency.	Kotlin Jetpack Compose Retrofit RoomDB SQLite

Beyond the code

I also perform traditional Central Italian folk music on organetto and chromatic accordion, mostly at village festivals and heritage events. 🪗 🪗 🪗
