Worked on the newrelic/entity-definitions repository to deliver a staging configuration that resolves relationships between APM applications and MSSQL instances. Focused on backend development and configuration management, the approach used YAML to define rules that map applications to database instances by server address and port, rather than host name, improving targeting accuracy when multiple MSSQL instances share a host. Introduced a staging-only validation workflow to test these rules against real span data before production deployment, aligning the relationship pattern with OTEL-APPLICATION-to-INFRA-MSSQLINSTANCE standards. This work enhanced database management practices and established a safer, more precise path to production rollout.
