Domain for portfolio website.

Personally I think full name would be best, looks more professional to me and should be easier to remember for clients, though the fact that it is longer could be considered a negative, honestly there isn't any one right answer to a question like this, what domain name suits you is very much a personal preference thing.

One thing I would like to add though is that I would actually recommend avoiding domain name TLDs (the part after the dot in your domain) other than the standard ones (.com, .net, .org, etc) new extensions like .xyz tend to be more confusing to people as they are not used to seeing and typing that extension, and emails from sites with those types of TLDs are more often categorized as spam by a lot of email providers, due to a lot of spammers having adopted those types of domains lately.

I think first one is better. Also, I would suggest to use .com domain instead of .xyz

If your websites is going to be for Indian people, .in is good enough.
