I have been using PegaRULES for approximately five years.

I am a software developer and have been using PegaRULES for the last seven years. I started working with this tool in late 2015, so my experience with it is more than seven years.

It has been more than 12 years.

I've been using the solution for nine years now. 

We've been a Pega partner for seven years. 

I have been using PegaRULES for 15 years.

Pega has multiple models, and I believe a few teams are cloud-based. Our organization is mostly moving to the cloud, but not entirely. However, we use on-premises deployment.

I have been using the solution for over ten years.                                                                                        

I have been working with the solution for four years.

I've been using this solution since 2003, so 17 or 18 years. 

I have been using PegaRULES for about a couple of years.

I have about five years of experience giving applications support for PegaRULES.

More than four years.
