Freelancing with various projects as an independent developer, thanks to this I got a little experience in managing a team, because. hired people when he couldn't do everything himself. But recently my account was blocked because of "unable to verify my identity". But I continue to work as a freelancer with customers directly.
Worked on projects: shark clean (robot vacuum cleaners), arobfuscator (library for android projects), fast energy (application for renting powerbanks) and many others.
