You can search by author on Web of Science to find documents published by the author (such as yourself). Search Last Name, First Name (or Initial). Then select "Create Citation Report" when you have the correct records selected.
Within Scopus, you can claim your Scopus Author Profile and link it to your ORCID iD. These processes help with author disambiguation and with keeping track of your publications and citation metrics.
In Google Scholar, you can find your h-index after logging into your profile (top left). Then go to your "My Profile," and your h-index will display in the top-right.
