Volodymyr Agafonkin is the creator of Leaflet, an open-source JS mapping library started in 2008 that is used pretty much everywhere on the Internet today. We end up nerding out on what makes building simple open source software & rendering maps online tricky but also so endlessly interesting. Volodymyr lives in Ukraine, a country shaken by a war for the past few years, which we also talk about.
