When we interview the only qualification that is acceptable as a substitute for experience is a degree, and then only from a recent graduate. Otherwise you will need to show some experience, preferably contribution to some project so that we can examine your code in the wild (you do document, comment and test your code don't you?) If all you can show is 'certification' your CV will get binned. Honestly, what do you expect? Certificates are for school sports day to make little children feel good about themselves, they will not make up for experience.
