    Hi, My name is Roy I install, configure, and administer open source auto dialers built upon the Vicidial platform. I have been installing and administering these VICIdial for years. I have a large number of clients, many of whom migrated from a hosted auto dialer, or were looking to move away from an older, expensive, proprietary auto dialer to VICIdial. Some clients use their Vicidial install to handle large volumes of inbound calls, and others use Vicidial for its powerful predictive outbound capabilities; most use Vicidial for blended inbound and outbound campaigns. No matter the case, Vicidial offers my clients compelling advantages over (much) more expensive proprietary auto dialers.

    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.
