We support public and private organizations

Our goal is straightforward – Our ideas about commercial contracting work hand in hand with systems integration and how to overcome implementation obstacles of emerging technologies that every organization must prepare for moving forward. Ultimately your mission is our mission, and NDT can provide the solutions that fit your organizations’ requirements.



As the name NDT implies, network design is our specialty. Founded as a sole proprietor in 1997, Network Design Technologies (NDT) has supported and empowered clients in various capacities over the years to help businesses reach technological goals and reduce hardware expenses. Joseph Ruffin is the founder and Chief Executive Officer of NDT. He started as a one-man IT specialist offering desktop support to primarily churches and local community action groups, also software/computer training, desktop and server support, and offsite data backup and storage management.

Data Backup and Storage

With the growing demand for businesses to be HIPAA and Sarbanes-Oxley compliant, backup and storage quickly became a niche for the company. At its peak, NDT provided 3 separate server collocations, with built-in redundancies, to operate small data centers running 24/7. Our team provided essential services to small law offices and doctor offices well before the widespread acceptance of cloud-based computing and systems management.
