Teaching advanced C++, including a brief understanding of data structures and generic programming plus Mathematical Foundations of Computer Science to advanced students so they can be ready to participate in more advanced courses of robotics and olympiads.

I worked on the Zoop project, a comprehensive ride-hailing service. I was the main developer of its core backend components including matching and pricing services.Offering rides to potential drivers was the main challenge of this service since each driver had a preference for its final destination, making a balance between the ride length and the price.
