    ***** Sorry, but I am currently too busy with other projects. ***** I am a Jane of many trades. I will give anything a good try at least once. I am a hard worker that takes pride in my work and I throw my all into everything I do. I am quite capable of easily learning new skills and have taught myself quite a bit through self-study over the last 10 years, from basic skills in digital art, programming, and web design to blogging, writing tutorials, and digital asset management using Extensis Portfolio 8.5. I love the challenge of learning new things. I have 5 years of Community Relations experience with an active developer/software users community. I am the administrator of all of the community's social media related accounts, which include Twitter, Facebook, and Friendfeed. I am also a forum moderator with excellent skills in sniffing out the sneakiest of spammers. While my programming skills are not at a level high enough to consider me for a coding job, I am very experienced with communicating with other developers. Patient, kind, and caring, I have excellent customer service skills, especially when it comes to dealing with "impossible customers" that make most people want to tear their hair out. As a blogger with 7 blogs, I have experience in the setup, securing, configuration, customization, maintenance, backup, restoration, writing, and posting articles to both Wordpress and Google Blogger based blogs, and can handle posting through both the web interface or with Windows Live Writer. I don't mind getting my hands dirty and messing around with HTML and CSS code when I have to. I can think in HTML.

    As an Enterprise Lead Systems Architect In my most recent job, I was directly responsible for the virtual architecture including but not limited to infrastructure design and deployment of a robust vmware multi-site architecture, the supporting network architecture, modular “siloed” clustered racks, NetApp 2240 and 3240 FAS/SAN systems, remote management and notification systems, and user provisioned lab environment that allowed test teams to provision physical and virtual environments on the fly. All systems were subject to DISA based STIGS and IA scans to verify compliance. As the lead, I directly manage several people on my enterprise team and my efforts touch every person on the project in some way. This interaction has allowed me to create a positive rapport with the entire team while keeping a thumb on several area perspectives. I also manage and assist with the install and design of our SharePoint /Project 2010 integration which upon completion was intended to pull in data from various sources including IBM Jazz Suite, custom built data management systems, and several real world diagnostic and filed measurement tools to display varying aspects of project progress and test data. This effort is still in progress and is coming along nicely. Also support the basic user needs including user account management, file share access and organization, PC issues, software installs and upgrades, and training. Finally, I worked with several integration efforts as an advisory capacity on COTS products that were used in fielded builds and R&D efforts. The infrastructure is comprised of 50+ Racked servers, 18 NetApp products, and several Cisco switches, routers, ASA’s and AirPort WAP’s etc… These resources are grouped in “Silos” and setup to be modular for movement to other sites as needed. I also designed and deployed our domain, complete with multiple DC’s that spread out DNS, DHCP, NTP, and AD with cross site architecture in mind allowing users to move from Lab to Lab with common resources and permission sets. I work directly with the network team and IA team on outward facing services to insure security and threat mitigation. I also run Facebook and Skype classes for the elderly with my company's outreach program. I'm versatile and well tempered and I have a decent network of helpful folks that i can lean on if things get tough. From Teaching to Fixing to Disaster Recovery and Risk Assessment Planning to Recording My Radio voice and Audio Editing Skills.. I have a deep bag of Tools. Let me use them to help you with your next project!  less

    I've worked in the field of information security for twelve years. The last 4 in an European Institution focusing on forensic analysis, web application security and incident response. Previous to my actual position, I have spent seven year working in an international Antivirus company (Panda Security) building vast knowledge of the methods hackers and viruses use to infect sites and computer. With so much exposure to real-world, up-to-date attack and defense techniques, I've developed a very effective and quick incident response process.  less
