This work aims to reflect on the collective female activism in technology under the prism of human-computational interaction, the culture of participation and cyberfeminism from Geek Girls Portugal community (the first launched in the country) ethnographic case study. From the monitoring of the group’s digital platforms, information was collected to configure an organizational and communicational system, as well as allowing reflection on the autonomy of members’ decisions, using tools of non-discretionary use for the inclusion of women in technology in one of the domains in which patriarchy dominates. Conceptual paradoxes about the culture of participation and the emergence of digital platforms, from the launch of the Web in parallel to the beginning of cyberfeminism, will be presented. This article will also present preliminary results of doctoral research on how female technological communities play a catalytic role in the inclusion, education and activism of Brazilian and Portuguese women in technology.
