Agile software development developers are responsible for developing software using the Agile methodology. This involves working in short cycles, or sprints, to deliver features and functionality quickly. Agile developers work closely with other team members, such as product owners and business analysts, to understand user needs and requirements. They then create software that meets those needs while also being scalable and extensible. In addition to writing code, agile developers also participate in code reviews, testing, and deployments.
