Summary
DevOps engineer and cloud architect with 10+ years across infrastructure, systems, and cloud automation. Sole owner of the full Azure estate at RDGFilings (CI/CD architecture, IaC: Terraform-first, with Bicep experience, security posture, and cost governance), serving as the bridge between application teams and infrastructure. Certified in Azure administration and DevOps (AZ-104, AZ-400) with deep experience migrating legacy toolchains (Octopus Deploy, Jenkins) to modern, credential-free pipelines.
Architected Azure DevOps CI/CD pipelines end-to-end, migrating legacy workflows from Octopus Deploy and Jenkins to Azure DevOps, reducing release cycles by 40% and improving deployment reliability.
Authored Terraform (and Bicep) IaC to automate provisioning of Container Apps, Function Apps, VMs, Key Vault, and networking, replacing GCP-based systems with consistent, repeatable Azure deployments.
Implemented OIDC / workload identity federation for all pipeline authentication, eliminating stored credentials and long-lived secrets from CI/CD and improving audit posture.
Modernized a legacy Duende IdentityServer: programmatic Key Vault secret loading and a shared data protection key ring in Blob Storage encrypted with a Key Vault master key, enabling first-ever horizontal scaling, with all traffic over private endpoints and zero public data-plane exposure.
Served as liaison between application architects, developers, and infrastructure, translating operational requirements into DevOps processes in an Agile environment; mentored junior engineers on Azure DevOps best practices.
Conducted a subscription-wide Azure security and cost audit via Resource Graph/KQL, including Reserved VM Instance retirement exposure analysis, driving remediation and cost-optimization decisions.
