PROFILE
Robert Sheridan
Sheridan developed and maintained the knowledgesystems-k8s-deployment repository, delivering a robust Kubernetes-based deployment platform focused on blue/green release strategies, infrastructure standardization, and multi-environment parity. Leveraging technologies such as Argo CD, ClickHouse, and Redis, Sheridan implemented zero-downtime rollouts, streamlined ingress and TLS management, and migrated core backends to modern data pipelines. The work included configuration management using YAML and Shell scripting, database integration, and resource optimization to support scalable, reliable operations. Sheridan’s engineering approach emphasized traceable, production-aligned deployments, operational efficiency, and maintainability, resulting in safer releases, improved rollback capabilities, and reduced operational risk across complex cloud environments.

Oct 1, 2025October 2025 monthly summary: Delivered reliability and stability enhancements across the knowledgesystems-k8s-deployment repo, with a focus on multi-environment consistency, streamlined staging, and storage modernization. Key outcomes include standardized Redis connectivity across green/blue deployments, consolidation of ClickHouse access to green primary with a single ingress, and stabilization of blue/green state after migration. Implemented offline beta environments with resource optimizations to support cost-effective testing, and established a robust staging domain routing with dedicated MSKCC deployment. Storage architecture was overhauled for gnap-gn-vep via StatefulSet and PVC removal to enable multi-node volumes and a simplified storage model. Overall, these changes improve deployment reliability, reduce operational risk, and accelerate future rollouts.

Sep 1, 2025September 2025 monthly summary for knowledgesystems-k8s-deployment: Delivered stability and maintainability improvements across MSK deployments with feature enablements, data persistence, and configuration standardization. A production rollback to legacy MySQL was performed to restore stability during the transition to ClickHouse, followed by ongoing hardening efforts. Highlights include ClickHouse deployment enablement for MSK portals, SSL trust store standardization, Redis data persistence, MSK-beta deployment documentation improvements, and cleanup of obsolete configurations. These changes reduce operational risk, improve data reliability, and streamline deployment governance.

May 1, 2025May 2025: Delivered a scalable, safer deployment framework using Kubernetes blue/green deployments, updated ingress/TLS for public data and portal, and enabled rapid rollback. Migrated the public portal to a ClickHouse-backed data path, deprecating the legacy public-data deployment while preserving blue/green parity for the portal. Implemented a dedicated 'prior' deployment with separate ingress and SSL for isolated testing and rollback. Expanded curated non-redundant studies in the public portal and performed deployment cleanups to improve consistency with the cluster. Demonstrated technologies include Kubernetes blue/green deployments, ingress/TLS management, ClickHouse integration, ConfigMap-driven configurations, underpinning CI/CD governance.

Dec 1, 2024December 2024: Delivered a Genie blue/green deployment framework with infrastructure standardization and production parity across public, private, and beta environments. Standardized deployment manifests, aligned replica counts with production, updated images and config maps, and refined ingress rules. Introduced RFC80 PoC on Genie portals and ensured consistent YAML outputs. Implemented deployment tuning (memory limits, node selectors, taints, labels) and naming conventions to maintain environment parity. Reduced memory footprint by scaling down Genie deployments and moved to master-branch images for consistency. The work strengthens release safety, accelerates rollout, and improves resource efficiency.
