    Senior Technology Consultant

    United States - Last active: 04/21/2014 - Tests: 2

    A little about me... Since young age I have been very passionate about technology and computer systems. In 2006, I turned my love for technology into a career, by starting my own company, called PC DOC (www.4pcdoc.com). In 2009, I graduated from DeVry University with a Bachelor of Science degree in Network and Communications Management. After receiving high quality theoretical and practical education, I finished with Summa Cum Laude and 3.97/4.00 GPA. Later, I pursued a Masters degree in Information Systems Management with concentration in Information Security at Keller Graduate School of Management. I finished with Distinction and a 3.90/4.00 GPA. Further, I continued getting involved with various types of computer and telephony systems and completed several IT certifications, including CompTIA Network+, Cisco CCNA, Microsoft MCP, Microsoft Virtualization Specialist, VMware VCA, Interactive Intelligence ICCE, etc. From servers, to networks, to telephony, to software - I enjoy and work with all kinds of technologies. That's why I have to wear different "IT" hats and would consider myself an IT Generalist. I have held several official titles, but presently I work as a Senior Technology Consultant and primarily work with the following: Microsoft technologies (Active Directory, Group Policy, LDAP, DNS, DHCP) Windows Servers 2003/2008/2012 and Small Business Server 2003/2008/2011 Microsoft Exchange 2003/2007/2010/2013 email servers Cisco technologies (Cisco ASA firewalls, Cisco Catalyst switches, Cisco routers) HP network equipment (ProCurve switches) Virtualization technologies (VMware ESXi and Hyper-V) SQL Server and Oracle databases Citrix Metaframe/XenApp and Microsoft Terminal Server/RDS Thin Client technologies (Wyse, HP) Servers and workstations (HP, Dell, IBM, Lenovo) VoIP Phones (Cisco, Polycom) IP PBX phone systems (Interactive Intelligence, Avaya) Digital and Analog voice gateways (Audiocodes, Cisco) SIP Trunk/PRI/T1 router and gateway equipment

    Customer Service Rep

    United States - Last active: 01/12/2014 - Tests: 2

    At this point in my career, I am hoping to utilize my knowledge of customer service and technology to assist others. Over the years, I have been at the forefront of many team driven projects. I have over 4 years of experience leading small and large teams to the project finish line. Due to my stage and production management roles, I am no stranger to “getting the ball rolling”, seeing projects to their completion, troubleshooting, and resolving a variety of issues along the way. The majority of my customer service background came from working in the retail and hospitality industry. For 3 years, I worked for Publix, a south eastern supermarket chain whose mantra is “where shopping is a pleasure”. Moreover, I have been employed by TJX, the Radisson Hotel, and a plethora of differing restaurants. I have been trained with the highest standard of customer support and satisfaction. My responsibilities have previously included resolving customer concerns, aiding customers in finding exactly what they are looking for, and creating a complete dining and shopping experience for all guests. As previously mentioned, I would now like to take what I have learned in the hospitality and retail industry and transition my future into the tech world. My fascination with computers began at a young age and has grown with me over the years. I’m well versed in Windows PC, Apple OS X, and Linux operating systems. I also exemplify proficiency in Microsoft Office applications and Adobe Creative Suite. In my spare time, I build computers which has helped me gain experience in upgrading, optimizing, and troubleshooting hardware and software. Among my acquaintances, I am typically the go-to for tech issue and I continually strive to learn all there is to know about current and future technology. Currently I co-own and operate Start 2 Continue Gaming News, www.start2continue.com
