Summary of the 12th Brazilian Conference on Software and the 1st Latin American School on Software Engineering.

The main goal of the Brazilian Conference on Software: Practice and Theory (CBSoft) is to bring together researchers, practitioners, and students aiming at fostering the exchange of experience about the most recent research, tendencies, and theoretical and practical innovations in software. The conference is the top conference in the field of Latin America. In 2021, the conference was organized virtually by Dr. Karine Roggia, Dr. Cristiano Vasconcellos (UDESC), and Dr. Paulo Boulsfield (Univille).
