Avi Schiffmann, a self-taught web developer, made a website, Ukraine Take Shelter, so that Ukrainian refugees can directly contact those who can offer free temporary housing.
ukrainetakeshelter.com can be accessed via any device connected to the Internet. Most refugees use smartphones when looking for housing.
Schiffmann also created nCoV2019, the worldwide coronavirus tracker, in January 2020. It became the most accessed coronavirus tracker globally.
Schiffmann receives messages of gratitude every day from the Ukrainian refugees and hosts from all over the world.
