About Us

The journey began with the first edition in Buenos Aires, hosted at Interbanking, and quickly evolved into a collaborative movement that brings together developers, speakers, tech leaders, and enthusiasts from different countries and cultures.

Over time, new supporters and organizers joined, strengthening the event and helping it reach new milestones. Since then, we have hosted several 100% free editions in iconic locations such as Florianópolis (CIASC), São Paulo (FIAP, ACT Digital, Red Hat, and Oracle), and Rio de Janeiro. Our most recent edition took place at Oracle São Paulo, where we brought together nine communities and more than 300 participants for a day filled with content, networking, and meaningful connections.

And we are just getting started. We already have three upcoming editions confirmed: Mexico, Colombia, and São Paulo once again. For this next edition, Oracle returns as our main sponsor, continuing to support DevConverge unconditionally since the very beginning and helping us deliver high-quality content and unique experiences to the community, always free of charge.

More than just an event, DevConverge is a platform for opportunities, a stage for great ideas, and a space for everyone who believes in the power of community.
