    With over three decades of experience under my belt as a network and security engineer, I've traversed the ever-evolving landscape of LAN/WAN network design, implementation, and maintenance. My expertise is not merely a testament to time, but also backed by credentials including Cisco CCNP (route/switch), a Cisco CCDP for network design, and a PCNSE for Palo Alto Networks. In my journey through the realm of networking, I've engaged with an extensive array of gear, from the minutest components to the behemoths, including Cisco Catalyst and Cisco Nexus switches. Additionally, I've delved deep into the intricacies of Cisco ASA and Palo Alto firewalls, sculpting security rules and configuring VPNs with precision and based on their published best practices. I am always available for consulting for short-term and long-term projects. Thank 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.
