Do training certificates make value for a web developer?

An easy answer to your question is “yes”. That’ll help strengthen your resume. A certification testifies your capability of developing and maintaining complex software development projects. You will enjoy preference over those not having a certificate. Having certifications alongside hands-on industry experience will give you an edge. Getting a job without industry experience can be tough. If you have done projects on that it would help. Take part in software development projects, learn to write code and test software.
