During June 2025, Andrii Telesh focused on backend development and container orchestration within the docker/compose repository, addressing a critical issue related to stack restarts after network configuration changes. Using Go and leveraging Docker Compose and networking expertise, Andrii engineered a stability fix that manages dangling containers and ensures clean disconnection from outdated networks, followed by reconnection to updated or resolved networks. This solution reduced deployment downtime and minimized manual intervention during stack restarts, enhancing reliability across environments. The work demonstrated a deep understanding of container lifecycle management and network behavior, reflecting strong debugging and maintenance skills in complex orchestration workflows.
