Dev Patel could get an e-mail address info@patel.dev. His website would be patel.dev.
If your name is e.g. Rahul Dev, you could get an e-mail address info@rahul.dev. Your website would have the address rahul.dev.
People with the name Dev should register Dev-Domains, as the .dev domain name is mirroring the real name. A website like rahul.dev is very memorable. The memorability of a website's domain forms a key to the success of a website.
The Dev-Domain is meant originally for developers. Not only developers, but anybody is entitled to register Dev-Domains.
