Platform Engineer building software development accelerating tools for OpsLevel customers and employees.• In my role as a Senior Software Engineer, I successfully led the major upgrade of OpsLevel's Terraform provider from SDKv2 to Terraform Framework. This undertaking mitigates the risk of costly infrastructure misconfigurations and runtime errors, established a solid foundation for future scalability and maintainability, and I provided mentorship and support to junior team members.• Leveraging my expertise in Go(lang) and GraphQL, I developed a code generating program that automates the conversion of OpsLevel's GraphQL API schema into accurate Go data structures used by OpsLevel's Go client. Increased automation in this critical program has expedited development of our command line tool, Terraform provider, kubernetes plugin, and other tools - enabling engineers to deliver more reliable code within reduced time constraints. This has already saved weeks of full time developer effort.• Boosting personal and team development efficacy is a key focus of mine. I have created dozens of workflow automation scripts across many code bases that are used daily by entire teams. I have also improved our CI/CD pipelines, maintained our kubernetes clusters, and terraform infrastructure.

Philadelphia, Pennsylvania, United States

Software Engineer working to boost dbtlabs' developer productivity. My work was split between an Internal Services team, a Release Engineering team, and an OSS Tooling Guild.[Release Engineering Team]• I significantly improved our most critical deployment pipeline by cutting one Github Action's time by 83% (12 minutes down to 2 minutes). This action is responsible for validating and updating values in helm charts that trigger deployments via ArgoCD across an array of microservices.• I developed a JavaScript Github Action that alerts developers when dbt's CI/CD pipelines failure. This action leverage's Slack's API, is tested with MochaJS, and provides developers with instant feedback on their submitted work.• In general, I developed Github Actions/Workflows, Go modules, Taskfiles, Python scripts, and Dockerfiles that integrated with Kubernetes, helm charts, and ArgoCD. [Internal Services Team]• To standardize tool versioning org-wide, I wrote a Go program that reads all "asdf" (tool versioning manager) configurations, shows versions of each tool used by each microservice, downloads those tools/versions locally, and configures those tools for use. Version mismatching was a costly hinderance to many developers and those supporting them (especially with kubectl). This automated program became the de facto means of resolving this issue.• Utilizing Terraform, I updated our OIDC providers and AWS IAM roles to achieve more secure authentication in our CI/CD.[OSS Tooling Guild]• In a day, I developed scripts (using gh cli, bash, awk, rg) that upgraded all deprecated versions of Github Actions used by 100% of dbtlab's CI/CD pipelines. Github was dropping node 12 support for its Github Actions and my work averted a CI/CD crisis at the day before support was dropped.• I mentored developers across multiple teams on Github Actions/workflows best practices, Python packaging, and promoting adoption of org-wide standards.

As a cleared Software Engineer at a national research laboratory, I am responsible for developing and maintaining robust codebases, automating workflow processes, and mentoring scientists in specialized areas of computing. My work concurrently spans across multiple teams and my code is scalable to some of the world's most powerful supercomputers.I created and maintain "Saloon", an open-source Vim plugin that empowers developers with real-time static analysis and code formatting - resulting in better code quality across the Department of Energy.• Provided physics program with 15+ years of metrics comparing performance data on multiple compilers by developing a Python script that parsed, processed, and formatted years of unstructured test data.• Drastically improved developer/value feedback loop by architecting efficient Gitlab CI/CD pipelines for multiple teams migrating away from Bamboo or lacking CI in general.• Refactored and upgraded large C++ program's infrastructure workflow program, documented the process, and delivered two talks on upgrading Python codebases.• Contributed to multiple High Performance Computing projects written in C++, Python, and Shell scripts.

As a missile maintainer, I performed inspections, repairs, and replacements of over 100 active Inter Continental Ballistic Missiles. Duties and responsibilities of this role included both working as the assistant team chief of a precisely orchestrated team and continuously developing my expertise as an individual maintainer.As assistant team chief, I was tasked with the proper handling and dissemination of sensitive information and equipment. Constant evaluation of the team's progress, safety, coordination of inter-agency members, and crucial decision making has led our team to perform outstandingly in over 20 major quality assurance inspections.As an individual maintainer, my responsibilities included perfect execution of repairs and inspections on 100s of electrical connections, specialized tools, technical equipment, and components. OSHA and DoD compliant handling of hazardous material and specialized vehicle operations transpired regularly. Proficient knowledge of coding systems, adhering to sensitive communication protocols, and immediate execution of contingency plans (if needed), were an absolute necessity.
