Once you have a few good publications, especially in reputable journals, editors often start inviting you to serve as a peer reviewer. Good luck

Dear Mohamed Ibrahim Hassan Farag

To become a peer reviewer or join the editorial board of an academic journal, researchers usually need a solid academic background, relevant publications in the field, and expertise that matches the journal’s scope. The most common way to start is by becoming a peer reviewer, which often happens through an invitation from editors, recommendations by colleagues, or by registering on the journal’s website or publisher platforms such as Elsevier, Springer, Wiley, or Publons (Web of Science Reviewer Recognition). Expressing interest directly to the editor-in-chief with a CV and publication record is also effective. Joining the editorial board generally requires more established experience, a strong track record of peer reviewing and publishing, and professional visibility. In most cases, editorial board membership is by invitation, although some journals allow applications through open calls on their websites.

Best regards
