As a weekend programmer, you work part-time on Saturday-Sunday to complete computer programming responsibilities. Your duties may require you to develop software programs, code program designs into a language a computer understands, test systems to ensure they are working correctly, and install computer updates. You may communicate with software developers as well as the client to ensure efficient translation and development of the program. Some programs may be developed in a couple of days, while other jobs may require multiple weekends to complete. The programs you create may be used for phone applications, operating systems, or websites. A weekend programmer may work for a company or provide freelance services.
