   • Designed and built an AI-powered GitLab Pipeline Investigator (Azure AI Foundry + FastAPI + Next.js) that discovers failed jobs across parent and multi-hop bridge/downstream pipelines, extracts log signals with secret redaction, runs LLM root-cause analysis with structured JSON output, correlates primary vs secondary failures, and exports PDF investigation reports. • Delivered Grafana DS query automation for IFS Cloud RTB: GitLab CI–driven pipelines that query Grafana datasources (/api/ds/query) for scalability (PROD/UAT), authentication response time, Oracle DB size, indexes, concurrent users, tablespace, session/process usage, and CPU metrics; export CSV; upload to Azure Blob and Azure Table Storage; and run retention-based cleanup with ServiceNow SR justification triggers. • Leading a platform initiative to standardize GitLab Runner deployments on Kubernetes entirely as code (Helm values/manifests per environment, dynamic child pipelines generating deployment YAML, Bash ops for health checks + GitLab API active-job polling) — safer cutovers and predictable shared CI fleets. • Lead cloud automation initiatives for enterprise customer environments, coordinating planning, delivery, implementation issue resolution, and team communication toward shared technical outcomes. • Built GitLab CI/CD automation for monthly OS patch assessment and installation across 3,000+ Azure customer VMs globally, supporting scheduled regional execution and operational stability. • Designed scalable capacity-management automation capable of securely logging into 1,000+ customer databases, extracting required capacity data, and storing outputs in Azure Blob Storage. • Migrated GitLab from on-premises to GitLab SaaS by conducting POCs, documenting transition gaps, supporting licensing, collaborating on SSO enablement, managing users and permissions, and moving projects to SaaS. • Implemented scalable GitLab runner architecture on Azure Kubernetes Service (AKS), transitioning from standalone and Docker runners to Kubernetes executor-based runners for efficient CI job execution and resource management. • Planned and executed Azure PostgreSQL Single Server to VNet-integrated PostgreSQL Flexible Server migration, including environment configuration, data migration planning, and team coordination. • Automated VNet peering, product delivery, product health checks, and cloud operations using Terraform, Ansible, PowerShell, Bash, Kubernetes, Docker, and Helm.
