    Vice President Solutions Delivery Delaware - Barclaycard Us
    Barclays Sep 2016 - Present
    London, Gb
    Manage team and the project/resource/schedule pipeline. Project Budget estimations. Review network designs. Review implementations and configurations.Highlights:Creation of modular project service catalogue and a new methodology for managing projects resulting in more accurate scheduling, improved delivery times, improved quality of work, reduction in defects, and a vehicle for continuous improvement. Rally as a tool was a large part of getting this implemented.Created automation using python that allows for a chain of configurations within a single workbook to be executed across devices identified within the workbook. This allowed end to end automated/scripted provisioning of "service chains", significantly reducing delivery times and greatly improving quality.Created automation using python for mass provisioning of F5 (GTM, LTM, WAF) resources according to user requests significantly improving deliverables time to mere minutes versus hours, days, or even weeks for large projects. Requesters simply choose an environment and provide some basic details versus needing to know all devices to provision.Created automation using python to completely copy an F5 virtual server and all its settings including pools, irules, profiles, etc. to enable migrations of a single or set of virtual servers to a single or many different load balances across environments.Created Cisco virtual device licensing automation using python and bash commands like grep and cut. Created automation using python for mass provisioning of certificates on F5 devices. CSR creation, certificate upload and installation, client and server profile creation, and attachments to virtual server. Use of Game theory and friendly competitions to improve administrative deadlines for timesheets, reviews, and other team administrative requirements. Many other systems geared toward increasing efficiency, reducing chaos, and increasing quality of processes and deliverables.
