Experience

Bank Automation System

I created a banking automation system that allows users to check their account data using face recognition and notifies the user via email if they lack funds. This project implemented facial recognition using OpenCV 2, Microsoft Face, UiPath Studio, and Azure Services.

Digital Car Dashboard

I developed a complete system meant to replace an old car analog gauge cluster with a new digital interface.

I used Unity to develop the user interface, which was made from:
• A 3D map, based on real data from Openstreetmap.org with textured buildings, streets, traffic lights, and so on
• A 3D car model that correlated with the actual car showing details like open doors or lights on
• Actual car gauges

The project required communication between the car's ECU and the screen devices. I implemented this using Python, C, and a Texas circuit board.

Augmented Reality Glasses

I created a pair of augmented reality glasses capable of displaying details a car user wants to view. The chosen car was framed in a bounding box along with the predicted model, make, year of production, and generation of the vehicle.
