Selected client contexts where I contribute with discretion, rigor and careful attention to business and technical constraints.
Greenfield development of an Android application used to perform in-flight inspection of airport guidance equipment with a drone. The application connects to the drone and ground station, handles flight path configuration, uses an NTRIP server for centimeter-level positioning, processes real-time flight data and displays results as charts, with real-time mapping and FPV video feed.
Development of a web application used to display in real time various data streams coming from an electronic board with an embedded microcontroller. The project is under NDA, so the presentation remains intentionally concise and does not go beyond that business-level description.
Studio
Pétanque, Fantasy Racing and other in-house projects shape my product and engineering approach, separate from client references.
An Android application designed to track scores, preserve match history and analyze player and team performance.
A turn-based tactical racing game set in a medieval fantasy world, somewhere between board game, controlled chaos and sporting brawl.
