Congratulations on your purchase and your Realtor for a successful and client fulfilling transaction.
Sure! There are numerous avenues to recommend your agent.
Since you are inquiring on this forum, the first place you should start is by finding his/her profile on Trulia and click the RECOMMEND button, then fill in the details.
You can also recommend them on other sites as well, like Zillow.com, Realtor.com, as well as other sites, and perhaps get your recommendation put on his/her ActiveRain profile if they have one.
But the best recommendation you can give would be by word of mouth throughout the community!
Thanks for supporting your Realtor and enjoy your property!
