Worked on the netbirdio/netbird repository to address a critical stability issue affecting deployments without netstack. Delivered a targeted bug fix in Go that ensures iFaceDiscover is properly initialized when netstack is disabled, preventing nil pointer dereferences in updateInterfaces and reducing the risk of crashes in edge-case environments. The approach involved careful debugging, code review, and comprehensive testing, with validation through continuous integration workflows. Focused on internal development and bug fixing, the work improved reliability for users operating in specialized network configurations. Demonstrated strong skills in Go, debugging, and CI-driven validation to enhance the robustness of network component initialization.
