Summary
🤩
Rockstar🎓
Top SchoolPatrick Carlisle is a Staff Software Engineer based in Portland, Oregon with 14 years of experience building and hardening back-end systems, tooling, and CI/QA infrastructure. He has deep roots in the Puppet ecosystem—contributing to core projects like puppet, hiera, puppetserver and the widely used orchestration tool Bolt—where he improved parsers, transport layers (SSH/WinRM), and test harnesses. At GitHub and Puppet Labs he has blended backend engineering with DevOps and test automation, routinely refactoring for maintainability and adding robust logging and error reporting. Patrick’s work shows a preference for pragmatic fixes that reduce flakiness in deployments and tests, such as merging backend lookup logic and tightening service restart semantics. He pairs a math-focused Reed College education with a pragmatic, systems-first engineering style and a knack for improving developer-facing tooling. An understated strength is his cross-cutting impact: touching parser internals, CI scripts, and transport implementations to keep large automation platforms reliable.

Aug 2017 - Nov 2017
Bolt is an open source orchestration tool that automates the manual work it takes to maintain your infrastructure on an as-needed basis or as part of a greater orchestration workflow. It can be installed on your local workstation and connects directly to remote nodes with SSH or WinRM, so you are not required to install any agent software.
Role in this project:Backend & DevOps Engineer
Backend & DevOps EngineerContributions:81 commits, 15 PRs, 12 pushes in 2 months
Contributions summary:Patrick primarily contributed to the Bolt project by adding support for running commands and tasks over SSH and WinRM. Their work included implementing transport mechanisms for both protocols, creating CLI interfaces, and enabling the execution of scripts. Furthermore, the user refactored the code to create transport objects and introduced a logging framework, demonstrating a focus on improving the tool's functionality and maintainability.
