Worked on the AdguardTeam/companiesdb repository, delivering a targeted update to the vpn_services.json configuration file to reflect the latest VPN service requirements. Focused on data and configuration management rather than application logic, the work involved JSON data manipulation and version control best practices to ensure all changes were clearly traceable. No code changes were introduced, which minimized deployment risk and streamlined the update process. The approach emphasized careful configuration management using Git and JSON, supporting maintainability and operational reliability. This work contributed to keeping the VPN services configuration current while maintaining a stable deployment pipeline and clear audit trails.
