AI agents built for production.
Alert investigation
SRE agent
Investigates Datadog alerts, gathers diagnostic evidence and identifies likely root causes. Shares findings and recommended actions in the alert thread, keeping the investigation and follow-up together so engineers can close the loop.
DevOps support
Phoenix DevOps AI assistant
Helps engineers investigate pipeline failures, answer infrastructure questions and resolve common DevOps issues. Analyzes job logs, explains failures and suggests practical next steps.
Read case studyContext-aware code review
AI code reviewer agent
Reviews GitLab merge requests against architecture documents and project files, using Jira ticket context and Confluence design references. Incorporates previous review feedback into later reviews, helping keep changes moving before engineering leads and architects give final approval.
About
CI/CD and production infrastructure.
I’m a DevOps Engineer with 3+ years building and operating AWS infrastructure and CI/CD for Spectrum’s e-commerce platform. I provision cloud resources with Terraform, build Kubernetes environments and contribute reusable infrastructure modules for application teams. My work spans release engineering, observability and incident response, with a focus on safe production changes and reliable services.
Skills and tooling

Cloud platform and delivery operations.
May 2023 – Present
DevOps Engineer
Spectrum (Charter Communications)
Build and operate shared AWS infrastructure and delivery tooling for Spectrum’s e-commerce platform, supporting 24 EKS clusters and 30 services.
Work areas across this role
v01Documented
Platform migration and reliability
- Led the e-commerce platform migration to new EKS clusters with zero customer downtime, coordinating cross-team testing and production cutover.
- Retired 3 legacy clusters and the old build-runner fleet within 4 weeks of cutover.
- Tuned workload resources, KEDA autoscaling and disruption budgets for 8 Kubernetes services, with zero-downtime rolling deployments across environments.
- Ran a production Kubernetes upgrade with a 24-hour monitoring watch and a documented change record.
v02Documented
AI-assisted operations
- Built engineering agents for alert investigation, pipeline troubleshooting and infrastructure questions.
- Added architecture-aware merge-request review before final approval by engineering leads and architects.
- Checked assistant changes with unit and property-based tests, and isolated investigation failures so they do not take the service down.
v03Documented
Cost and FinOps
- Own cost reporting and planning for 2 AWS accounts. Built the 2027 budget and presented the forecast to leadership.
- Identified a roughly 40% gap in the default billing view and corrected how costs were reported.
- Measured a 73% reduction in production EKS control-plane cost (Feb–Apr 2026); development EKS and compute costs fell 52% and 38% respectively after migration.
v04Documented
CI/CD platform engineering
- Standardized Akamai cache invalidation across 9 services with one reusable GitLab CI/CD component, retries and a dry-run mode.
- Migrated build configuration for 9 Angular applications to fail-fast checks while keeping older release branches deployable.
- Fixed a CI defect that reported failed Helm deployments as successful, so failed rollouts stop the pipeline.
- Built delivery workflows for updating feature flags and application configuration without redeploying applications.
v05Documented
Infrastructure as code
- Cut a Terraform apply from repeated 10-minute timeouts to about 2 minutes by correcting the order of resource updates.
- Provisioned managed Redis and PostgreSQL infrastructure with Terraform; extended shared modules and added Redis replica autoscaling.
- Redesigned a load-balancer change to preserve shared resources and avoid disrupting other services.
- Created QA, UAT and performance environments to support feature validation and release testing.
v06Documented
Security, compliance and delivery
- Integrated browser-based security testing, Veracode and SonarQube into application delivery.
- Strengthened repository security and supplied evidence for PCI compliance reviews.
- Led disaster recovery validation and coordinated production incident response with application teams during on-call shifts.
- Authored release documentation and operational runbooks for repeatable deployments, investigations and handovers.
