Can anyone suggest me How can I do adobe certification in AEM less than one year experience?

Hi @vinuu123, please have a look into this topic

I believe it covers what you need. I've listed there Professional level certificates, that should match your level of experience. It also links to Adobe pages that describes each certificate in the detailed way.
