Summary
👤
Senior🎓
Top SchoolRyan Gardner is a Staff Software Engineer with 15 years of experience building high-performance, large-scale distributed and low-latency systems, currently driving engineering at Upside. He brings deep JVM expertise—everything from Spring Boot services to low-level GC troubleshooting—and a pragmatic approach to APIs, favoring GraphQL and gRPC while using REST where appropriate. Ryan has led framework and architecture efforts, mentored teams, and previously shaped platform infrastructure at Cox Automotive and Dealer.com. An open-source contributor, he improved GC log analysis and added performance benchmarks and DynamoDB support to popular Java libraries, reflecting a focus on observability and runtime performance. Based in Burlington, Vermont, he combines hands-on coding with system-level thinking and a tendency to keep his profile understated, so his public tech list may lag behind his current toolkit.

chewiebug/GCViewer
May 2013 - Sep 2013
Fork of tagtraum industries' GCViewer. Tagtraum stopped development in 2008, I aim to improve support for Sun's / Oracle's java 1.6+ garbage collector logs (including G1 collector)

Contributions summary:Ryan primarily focused on improving the `gcviewer` project's ability to parse and analyze Java Garbage Collection (GC) logs. They added support for handling decimal values in G1 GC logs, as well as logs using the PrintAdaptiveSizePolicy flag. Furthermore, the user added preliminary support for parsing PrintGCCause strings and logs with the GC Remark phase, enhancing the tool's ability to interpret various GC log formats. These changes demonstrate a focus on expanding the functionality and compatibility of the GC log analysis tool.

Feature Flags for the Java platform
Role in this project:Back-end Developer
Back-end DeveloperContributions:5 commits, 2 PRs, 5 comments in 3 months
Contributions summary:Ryan primarily contributed to the performance testing and benchmarking of the Togglz library. Their work involved creating and integrating JMH microbenchmarks to compare the overhead of Togglz feature flag lookups against simple boolean checks. Furthermore, the user implemented benchmarks centered around feature state options, including those leveraging activation strategies such as the ScriptEngine-based strategy. These efforts provide valuable insights into the library's performance characteristics. The user also added DynamoDB state repository.
