OSS Engineering refers to the practice of developing and maintaining Open Source Software, which is software that is made available to the public for free. This type of software allows users to view, modify, and distribute the source code, fostering collaboration and innovation among developers. In OSS Engineering, contributors often work together in communities, sharing their expertise and resources. Projects can range from small tools to large systems, and they often rely on platforms like GitHub for version control and collaboration. This approach not only enhances software quality but also promotes transparency and accessibility in technology.
