PROFILE
Craig Dempsie
Worked extensively on the utilitywarehouse/kafka-cluster-config repository, delivering eight features and resolving one bug over eight months. Focused on enhancing data pipelines and infrastructure, this developer implemented secure Kafka client configurations, optimized data retention policies, and introduced TLS-enabled modules for resilient message backfill. Leveraging Terraform and HCL, they managed cloud infrastructure and configuration, ensuring safe, observable changes and streamlined rollouts. Their work included integrating Elasticsearch for improved data searchability, automating vulnerability data hygiene, and refining customer support messaging workflows. By emphasizing Infrastructure as Code and robust cloud management, they improved system security, data integrity, and operational maintainability across environments.

Feb 1, 2026February 2026: Reverted the temporary hotfix for the Customer Support Communications Projector, restoring the Kafka cluster config in utilitywarehouse/kafka-cluster-config to its standard production baseline. This action eliminates the one-off workaround, reduces operational risk, and improves long-term maintainability. No regressions were observed after the revert; monitoring and change-logs confirm stability.

Jan 1, 2026Concise monthly summary for 2026-01: Implemented TLS-enabled backfill modules for Braze Unicom and Customer Support, securing message backfill processing end-to-end. Introduced a second, TLS-protected consumer with bad-message skipping to prevent outages during incidents (CRM comms projector). Deployed production TLS certificates for Unicom comms backfill into William, enabling production-grade backfill. Completed backfill TLS cleanup after completion to reduce configuration debt and keep the environment lean. These changes improve security, reliability, and business continuity by ensuring secure, resilient backfill of missed messages and faster remediation paths.

Sep 1, 2025In Sep 2025, delivered Data Retention Policy Optimization for Customer Support Kafka Topics in utilitywarehouse/kafka-cluster-config. Implemented Terraform/config updates to set coffee topic to 1 month retention and applied defined retention windows to other topics: 1 year for some; 7 years for payments_audit_log_v1; 4 years for reminders, vulnerability, notes, and ticketing. This work was implemented through three commits: 16be399b91af51c67ebed9b727ee2c498d1cc6de, 993dcb0a03cbe568171f5f50f3e7d7c993d15c11, 5bfbf25808a5cc1f343b70396e8a5edc2e6a26ed. These changes reduce storage costs, improve governance, and set a repeatable pattern for policy updates via Terraform.
