Our Story

Our story began two years ago when the Barnes family moved to Palestine from Dallas. Joseph Barnes identified a gap in services and realized there is a need for software development in East Texas. Having over 11 years of experience as a software engineer, he decided to make his services available to his neighbors. Thus, Longhorn Software Solutions was born.

Longhorn Software Solutions offers application development and maintenance services for small to medium-sized businesses in East Texas. Our solutions include websites, business process applications, and custom software.
