I've been a Wikipedia volunteer since 2012, known as Aced. In my volunteer capacity, I'm an administrator & bureaucrat on Ukrainian Wikipedia, typically devoting my time to admin and patrolling maintenance tasks, as well as to writing occasional articles on American politics and whatever fascinates me at the moment.
As a programs coordinator at Wikimedia Ukraine, I'm responsible for overseeing realization of WMUA projects according to the strategic plan; ensuring communication between volunteers, staff, partners, and other stakeholders; lead the team of several staff members managing specific projects and programs, such as international Wiki Loves Earth or the Wikipedia Education Program.
