Worked on the k-wall/kroxylicious repository to address reliability issues in environments with split-horizon DNS. Focused on improving the ImmediateCloseSocketServer by modifying its socket binding approach, using the ServerSocket constructor to bind directly to the wildcard address and eliminating reliance on InetAddress.getLocalHost. This Java-based solution enhanced connection reliability and reduced test flakiness, particularly in ResilienceIT bootstrap tests, by preventing DNS-related hangs and enabling faster fail-fast behavior. The change streamlined test stability and simplified the codebase, resulting in more predictable deployments across VPNs and corporate networks. Core skills applied included Java, networking, and unit testing methodologies.
