Worked on stabilizing the subfinder repository by addressing concurrency and CI reliability issues using Go, YAML, and GitHub Actions. Focused on improving the robustness of HTTP handling in concurrent workflows, introducing separate response variables to prevent nil pointer dereference errors when requests fail independently. Restored the examples directory in the build-test workflow, ensuring that go run . executes in the correct context and that continuous integration processes remain stable. These targeted bug fixes enhanced error handling and reduced production risk, supporting more reliable and scalable network scans while lowering debugging time and improving the overall maintainability of the codebase.
