  • S
    Tech Lead
    Seebot
    Jun 2018 - Sep 2019 (1 year 4 months)
    We assembled an entire smart traffic light (STL) that can sense streets using cameras and act (open/close) autonomously. Our main achievements were:
    • When I led software engineers, we created: STL hardware and software controllers, traffic simulators for traffic optimization, and dashboards.
  • S
    Data Scientist
    Seebot
    Oct 2015 - Jun 2018 (2 years 9 months)
    We created a traffic simulator using SUMO (Simulation of Urban MObility). Our main algorithm on this simulator had 200% to 400% waiting time optimization on light to medium vehicle traffic. We also deployed our STL in four real crossing roads. To achieve this, we had to:
    • Do researches in traffic optimization area by using smart traffic lights.
    • Design and develop optimization algorithms for smart traffic lights.
    • Design and create an embedded distributed real-time systems for the STL with a microservice architecture.
