Developed VK domain support for the AdguardTeam/companiesdb repository by updating backend configurations to recognize and process requests from vk.com. This feature expanded the platform’s domain routing capabilities, enabling accurate handling of VK-related traffic and improving user coverage for VK workflows. The work was implemented using Python, focusing on backend development principles and configuration management to ensure reliable and auditable changes. No major bugs were addressed during this period, but ongoing monitoring and backlog grooming were maintained to support future sprints. The update enhanced the reliability of domain handling and provided a clear, traceable commit history for future reference.
