A Golang developer uses the Go programming language to develop software. Go (or Golang) is particularly suited for building scalable, high-performance web applications and services. It is designed for networked computing and can handle multiple tasks simultaneously through its built-in support for concurrent processing. With experience as a full-stack developer, they bring a valuable skill set to the table, as they possess expertise in both front-end and back-end development, allowing them to contribute to various aspects of the project. However, Golang developers typically work on backend development, creating the logic that powers web applications, microservices, APIs, and other Golang applications. They may also be involved in optimizing software for performance, debugging and fixing issues, designing and implementing clean architecture, writing tests, and maintaining code quality.
