Founder, CEO, Editor-in-Chief. I have been creating technology related websites and platforms since 2011. My main project right now is Deals Therapy. I want to help people save money, time and effort when buying electric bicycles, electric scooters, projectors, smartphones, robot vacuum cleaners and other products. I am fanatical about what I do because I believe I am doing a useful and necessary thing.
