    I have been working in IT for over 15 years now, and loved almost every minute of it. While I have experience with everything from Netware to Windows to Aix on the administration side, I primarily specialize in virtualization now, particularly using VMWare (though I have used Hyper-V more than I care to remember). To help back up that systems experience, I also have extensive experience managing storage hardware, particularly EMC and Netapp SANs and Brocade and Cisco MDS fiber channel switches. Combine this with my experience managing network hardware in one of the largest military campus networks in the Middle East, and everything in the datacenter is covered. I started my certifications with Novell and Microsoft, but have also received certifications from Comptia and Cisco at times, along with training from Netapp. Whether you are looking for someone to handle a small server issue or a full infrastructure upgrade and migration, my skills, experience and talents fit the bill. I hold VMware VCP-DCV and Cisco CCNP:DC certifications, among many others  less

    I am an extremely skilled, motivated, and highly knowledgeable IT professional with 15+ years in the IT industry. I am also an EC Council Certified Ethical Hacker, and in addition to security services, I provide a vast array of technical solutions to both businesses and individuals. From network/server/workstation planning and implementation to advanced troubleshooting and traffic analysis, I am THE answer to your technical demands. Add to this the fact that technology isn't just my profession; it's my passion, and you will discover why my clients have been with me for years and wouldn't consider switching. I absorb and become well-versed at any issue thrown my way, and will get to the bottom of whatever roadblock I encounter. Who I am not: your average neighborhood tech geek, a rep from a fly-by-night shop, or someone sending proposals to any listing that appears. I choose my applications very carefully, and make sure I have budgeted enough time to complete the task required. I also do not apply for jobs that I'm not 100% certain I can handle. Due to these and many other reasons, I have built a solid name for myself locally, and will do so here as well. You'll be glad you chose to have done business with me, and I look forward to meeting your technological challenges head-on.  less
