RomIT Project Consult

Together with the team, I worked on a Large System Integrator (LSI) project—an internal solution developed for a client, specialized in managing various types of equipment used in border defense.

I was also responsible for implementing a kiosk-style project, where users could order taxis through interaction with a touchscreen terminal. The solution was designed for Henri Coandă Airport.
