PROFILE

Zafer Balkan

Zafer Balkan enhanced cross-platform reliability and modernized core infrastructure across multiple open-source projects. He improved the wazuh/wazuh and wazuh/wazuh-agent repositories by refining test suites to handle non-UTF-8 filenames, stabilizing CI pipelines, and hardening UTF-8 validation for file integrity monitoring. His approach involved separating platform-specific tests, improving platform detection, and reducing flaky results, which led to more robust integration and system testing. In dotnet/command-line-api, Zafer upgraded the codebase to .NET 8.0, aligning dependencies and tests with the new framework. His work demonstrated depth in C, C#, Python, and CI/CD, focusing on maintainability and cross-platform correctness.
