    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.

    Hey, I'm James. I've been a self-employed business network and server admin for 21+ years. I've worked with all flavors of Linux and Windows for some of the best businesses in the country. My average customer that I've worked with has been with me over 10 years. I specialize in analyzing current infrastructure and determining the needs of my clients then providing a written plan to correct any issues and protect the business systems from hackers and cryptolockers. In one of my recent projects, I consulted with a six billion dollar, publicly traded company to completely redesign their infrastructure to have redundant firewalls, VMWare host servers, leased fiber lines directly to Amazon AWS with a VPN backup over a regular Internet circuit that would automatically fail over in case of any circuit issue. The vmware servers would auto migrate the guests in the case of overload or host server failure. All power systems were redundant with two powersupplies for each piece of equipment. At the end of this project, we had reduced their monthly cost of management by over 25,000 per month and reduced their server load from over 20 servers to just 8 servers. When you hire me, here's what you can expect: 1. First, click the invite button to invite me to your job. 2. Once everything is accepted, I'll jump on the phone or a zoom with you 3. We'll go over the details of the job and I'll ask questions to drill down to the specific goals you want to accomplish. 4. I'll provide you with a high level written plan to address your goals along with expected time needed to complete your project. 5. When we agree on the timeline and process, I will execute the plan. So, if this sounds good, just click the "invite" button and we can start.
