Isabella Aidar, known online as Socialista Champagne, is a Brazilian‑Canadian political educator, writer, and UX & interface designer for Tech for Palestine.

With a focus on anti-imperialism,  geopolitics, and applying historical and dialectical materialism, Isabella hopes to make materialist analysis and Marxist-Leninist theory accessible to a wide range of audiences from all sorts of biases and ideological backgrounds. She takes inspiration from Frantz Fanon, Michael Parenti, and the Communist Party of China to ground her theoretical knowledge in contemporary reality.

She is the lead UX/UI designer for JayWalk app, an app for activists and organizers to share their events and find community related to various social justice and liberation causes.
