    A Top-Rated, Expert-Vetted VoIP/Software engineer with over 20 years of experience. My experience ranges from Asterisk/FreePBX phone systems, SMS messaging, Linux operating systems, to network administration. I believe you deserve a more professional, reliable, and personalized business experience, and I bring that mindset to every project. Whether I’m developing top-secret code for Lockheed Martin, or AI telephone agents for Nomo, or creating privacy-first communications for Mecca Hosting, Inc, or designing secure, high availability Asterisk systems for TeleConnx Inc., or handling difficult troubleshooting tasks, I always commit myself to the same standard: creative, client-first solutions and efficient, high-quality work, completed in a fraction of the time. I have a passion for transforming mundane phone interactions into exciting customer experiences, and I lean on decades of experience to create solutions that others would find impossible. In short, I can make your telephone system do pretty much anything, including turning on your coffee maker in the morning. I look forward to working with you!
