Lead virtualization architect

Responsibilities:

• Architected and Engineered migration from XenApp 4.5 to XenApp 5 and then to XenApp 6.5 that is used on a variety of devices from Apple IPad, corporate issue PCs and a wide range of thin client devices.
• Designed virtual provisioning server environment reducing overall need for systems maintenance and downtime on the citrix environment, currently the environment can run with only 1 administrator.
• Architected Netscaler solution utilizing clustering to migrate existing HA solution into a more resilient load balanced environment. Upgraded current SDX units from v9.x to v11.x.
• Collaborated with primary counterpart to automate the delivery of Citrix Edgesight weekly reports using a combination of powershell and Microsoft Orchestrator to deliver concise reports to each stakeholder in the department.
• Engineered AppLocker solution via Group Policy and Local policy to enable proper lockdown policy on applications that are subject to strict licensing audits.
• Converted existing scripting into PowerShell format in order to deliver next generation speed while enabling the shared environment to have control elements in place for all service areas to have a consistent desktop experience.
• Reduced overall servers needed and increased per server/user capacity through correct design processes and working with my team members on how to get more from the systems we were able to utilize.
• Increased overall system performance from system response time to user logons, initial user logins were upwards of 45 second to 1 minute in XenApp 4.5 which were reduced to 10-20 seconds. XenApp 6.5 initially had a 1 minute 30 second average login time which has been reduced down to 10-20 seconds. Multiple factors played a role in each of these environment which had a direct effect on user login time, I was able to present management with a concise reason to why these times were being seen as well as give them multiple options on how to speed them up dramatically while keeping certain user settings in place so that we would not lose user acceptance.
