My name is Prathamesh and I’m a technologist & educator with a rich background in public safety technologies, robotics, computer networks & AI. I received my Master’s in Electrical Engineering from the University of Southern California and a Bachelor's in Electronics & Telecommunication Engineering from the University of Mumbai.

I have designed public safety technology solutions for both government and private organizations during my time at Motorola Solutions & Silicon Valley Startup, Cobalt Robotics. Some of my clients include governments of the US & UK, Dutch Telecom Giant KPN, Slack, General Motors, and the largest e-commerce company in the world.

My vision is to leverage my 8+ years of corporate and startup experience in the public safety systems engineering domain to foster innovation and create better tools and frameworks to help future technologists to become all-rounded engineers. And, by bringing real-life experience into academia, I hope to spark more fires in the hearts of young tech enthusiasts and empower them to solve the emerging social challenges through the power of technology.
