• Quidalert: a network alert manager that can be used by users to send alerts and receive help from others: when the server receives an alert from a client (which runs the mobile app), it takes the alert description and the alert gps location, then it sends a push notification to all geolocalized nearby clients and to the closest chief (called “chief manager”), to notify them about the alert. Stack: FastAPI, Flutter, PostgreSQL, Redis.

• XSS Exec Checker: a command-line tool written in Python language, useful to check if a specific web endpoint is vulnerable to XSS attack. The program runs a static check and a dynamic check (using a browser engine to detect XSS execution).

• Sentinel: an educational prototype that demonstrates how a multimodal AI system can ingest, analyze and summarize heterogeneous data streams in real time. The project is inspired by conceptual ideas seen in fictional films such as Person of Interest, but this implementation is strictly a technical experiment focused on concurrency, pipelines and AI preprocessing.
