What is a sole developer?

Sole developers are software professionals who are responsible for the entire development process of a project or application, working independently without the support of a larger development team. They handle everything from planning and coding to testing and deployment. This role requires a broad skill set, strong problem-solving abilities, and good time management, as sole developers must manage all technical and often some non-technical aspects of their projects. Many sole developers work as freelancers, consultants, or founders of small startups.
