- EData ScientistEarlySecJun 2018 - Mar 2019 (10 months)We created security systems to advise our clients on assurance issues. We used Natural Language Processing (NLP) techniques to filter, train, classify, and cluster social media messages. This way, we could alert our clients if something unusual was happening.
- STech LeadSeebotJun 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.
- SData ScientistSeebotOct 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.
