He is passionate about empowering other team members to work more efficiently, whether it be through the development of command line interfaces for orchestrating cloud stacks, customized CI/CD pipelines, Jira and Slack hacks, or Docker-izing all the things. In addition to his technical talents, Tyler is a trusted partner to our business stakeholders, and represents the concerns of engineering very well. He is seen as a leader among his peers, and is very comfortable taking on whatever roles we give him. He is simply an outstanding colleague in every way imaginable." and "While at SANS, I saw Tyler fulfill an impressive number of roles. Senior Backend Developer, Front-end Developer, DevOps Engineer, Systems Administrator, Database Administrator, Network Administrator, Support Engineer, Team Lead, Architect, Technical Writer, Integration Engineer, ELT Engineer, Virtualization Engineer and many many more. This impressive number of hats was only outdone by how well he performed at all of them. Tyler is a passionate, experienced, and highly skilled programmer. He has experience with many different types of languages. These have all served to solidify his deep understanding of core programming concepts. His attention to detail makes him very skilled at analyzing requirements, identifying missing requirements, creating detailed plans, and implementing robust code. Tyler has a history of developing many different types of applications. The result is a vast and well-rounded skill set. He is also an amazing troubleshooter. I really enjoy working with Tyler on support and performance related issues. He's very calm and doesn't let urgency cloud his judgement. He's very good at weeding out irrelevant errors and surfacing the ones which are likely the root cause. Using these errors, he quickly identifies suspect code. He comes up with well informed theories based on years of experience. Has a high rate of successfully diagnosing issues on the first try. He can replicate most issues quickly and validate his theories with little or no disruption in production environments. Tyler is a passionate and talented developer of automation. If he ever does the same thing twice, he quickly finds a way to automate it. His knowledge and expertise in shell scripting is unmatched. It's awe inspiring to watch how quickly he writes Bash scripts to automate tasks like surfacing related errors from GBs worth of log files. Or create a Jupyter notebook to perform a rolling deployment to 6 application servers. Or manage a release encompassing dozens of individual microservice repositories with a well designed meta repository and code building pipeline. He is passionate about and has a deep understanding of security. Tyler has a wealth of knowledge regarding every layer of the stack. He also knows every protocol being used by a system. This gives him an innate ability to pre-determine the most likely attack vectors. He also has the knowledge required to design secure systems from the ground up. He believes in “Security by Design” and a layered approach to system security. He desires to ensure that security is a first class citizen. This leads to top-tier system security that never gets bolted on at the end. It’s been an honor and privilege to work with Tyler. If given the opportunity, I wouldn't hesitate to do it again. He's very hard working, talented and humble. I'd recommend Tyler, without reservation, to any organization looking for a highly skilled Senior Developer, DevOps Engineer, Systems Administrator or any other related position."
