Experience

  • #

    Senior Delivery Engineer, 

     —    5 years

    • A top client, to keep the multi-million dollar per year contract, requested a verifiable report detailing the interconnections match the explicit specifications within 6 weeks. Tasked to me, as one of the few who had the skills and knowledge needed. I presented to the client, 5 weeks later, the solution I had designed, built, and deployed; which later received 3 separate awards for its success. A service that utilized in-band and out-of-band connections matching source ports to their destination port through the use of IP tables, ARP tables, IPMI, Redfish, iLO, iDRAC, and LLDP automated validation of in-band and out-of-band network connections between servers, switches, and routers using Ansible to traverse the network connections.
    • Performing validation, remediation, and verification on hundreds of devices a day is a major bottleneck in WWT's supply chain, made even worse due to the one-off solutions each ITC team seems to have come up with themselves. Working with a solutions architect, we built a framework to discover servers, switches, routers, and storage devices using services like mDNS, PXE, iPXE, and DHCP; and generate detailed reports using numerous CLI tools, BMC management tools, and on-board RedFish REST API. Facilitating fully automated validation of internal hardware against expected build configurations, remediation of firmware versions, and upgrading the operating system to match required specifications. Providing a single, fully automated solution that, for our test team, improved throughput from 10 a day to 60 devices a day without any errors.
    • Initiated a weekly self-paced training session to explore concepts, terminology, and processes used in both software and DevOps, improving the communication and cohesion between members of these teams.
    • To improve usability and maintainability of projects used by teams in the ITC, I wrote custom Ansible plugins for simplifying complicated task logic, inventory, and logging requirements. Now used by 11 teams, it reduced the support requests to developers from 3 a day to once a week or less.

    Teagan's ability to look at a complex problem and reduce it, quickly I might add, into an extendable and reusable architecture is surpassed by no software engineer I have ever worked with. In the matter of 3 hours she had designed and beta spec'ed the architecture for a commission/invoice integration with a financial system; it was approved by the client in ONE meeting.

    I have had the pleasure of knowing Teagan for the past three years now, and have worked side by side with her for the last year. I can say without a doubt that if she quit her current job, I'd likely be applying to her new job; She is that great to work with, always honest and always knowledgeable of the task at hand.

    Teagan is a relentless scholar, either from the academic perspective nearly having four degrees to the community side and her continual contribution to open source. Teagan also is enthralled with automation and has taken it upon herself to automate her home and daily life where possible.
