Justus enhanced the Dropbear build system in the enfabrica/enkit repository by integrating zlib as a Bazel-managed dependency, enabling both system-installed and in-tree builds for cross-compilation scenarios. This approach improved build reliability and reproducibility across multiple architectures, streamlining the development workflow. In a subsequent effort, Justus upgraded the Boringssl cryptography library and removed legacy platform-specific patches, which reduced compilation errors and simplified ongoing maintenance. Throughout these projects, Justus applied expertise in build system configuration, dependency management, and Bazel, delivering targeted improvements that strengthened the stability and maintainability of the enfabrica/enkit build pipeline for future development.
