About Chris Paul

As a Sr. Solutions Architect at Rex Consulting, I have been bringing order and clarity to technology solutions for over twenty years. I specialize in designing and implementing monitoring, email, and directory server systems (LDAP) for various clients, including AT&T, DOE, DuPont, Kaiser Permanente, and Neiman-Marcus. I have also leveraged my expertise in Linux, network administration, cloud, and SaaS/PaaS solutions to deliver high-quality and scalable results.With over 30 years of experience in computer technology, I have a proven track record of innovation and excellence. My hands-on experience with Linux and Windows Server go back to 1994. Since then I've been implementing both email, DNS, and directory systems in both Linux and Windows.I have launched and operated two very successful businesses—an consulting firm and a SaaS email venture which, besides being profitable, provided invaluable experience. I am passionate about mentoring and guiding teams, and I have a unique perspective that enables me to excel in various roles. My goal is to foster the success of Rex Consulting and its clients by providing cutting-edge and reliable solutions.
