    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!

    Hello! I am a Telecommunications and Networking Specialist and I primarily work with Cisco networking technologies, both wired and wireless, routing, switching, IP telephony and VoIP. Since 1999 I have had the privilege of working with multi-site organisations where these technologies have been applied to the fullest extent. In most cases, the applications of these technologies have been on an “enterprise” scale, with hundreds of users (or even tens of thousands for some municipal Wi-Fi networks) and tens of locations. I've been designing and managing Cisco IP telephony and data networks as well as writing proposals, RFPs and technical writing projects for large scale organisations in both the public and private sector in multiple countries including the USA, the UK and Greece. I’ve been technical manager of European funded projects and administrator for IP Telephony networks, data networks, municipal Wi-Fi networks and metropolitan fibre optic networks. I have a CCNP certification and four CCNA certifications in Routing & Switching, Security, Voice and Wireless. I am currently working towards my CCNP Collaboration and my CCIE certifications. I am also an instructor for Cisco Academy. Although I live in Greece, I was born and raised in Canada, so English is my first language. My Philosophy: The quality of my work and my services are of great importance to me. My goal is to always be on time, consistent and pleasant to work with. I will be clear and concise from the beginning, letting you know what each job entails and how much time it will take. All this will be done honestly, without fanfare and with integrity. I would even say that I will be chivalrous with my obligations towards you. This is good for you, because you’ll get done what you need to get done. This is good for me as well, because you will be pleased with my work and you will give me a good review. It’s a win-win situation! So I look forward to having the pleasure of working with you.
