• Assembled an entire Smart Traffic Light (STL) that can sense streets using cameras and act (open/close) autonomously. Main achievements were: led 5 software engineers, created an STL hardware and software controllers, traffic simulators for traffic optimization, and web dashboards.

• Created a traffic simulator using SUMO (Simulation of Urban MObility). My main algorithm on this simulator had 200% to 400% waiting time optimization on light to medium vehicle traffic.

• Deployed our smart traffic light in 4 real crossing roads. To achieve this, I had to: do research in the traffic optimization area by using smart traffic lights, design and develop optimization algorithms for STLs, design and create embedded distributed real-time systems for the STL with a microservice architecture.
