About

Hello!

I’m Guy Payne, a Senior DevOps Engineer at LendingTree. I spend my days building scalable, reliable infrastructure and figured I’d document what I learn along the way.

What I Do

Most of my work involves cloud infrastructure, security, and automation across multi-cloud environments. Here’s what I work with daily:

  • AWS Multi-Account Architecture - Managing complex AWS Organizations with multiple production accounts, CloudFront CDN distributions, Lambda functions, and cross-account networking
  • Security & Identity Management - AWS WAF configurations, AWS IAM policy management, Identity Center (SSO), KMS encryption, SailPoint integrations, and certificate lifecycle management
  • Container Orchestration - Managing production AWS Elastic Container Service clusters, containerized applications, and Kubernetes (AKS) clusters
  • Infrastructure as Code - Terraform deployments, AWS SAM (serverless applications), Azure DevOps pipelines, and automated infrastructure provisioning
  • Incident Response - Leading critical incident resolution for business-critical systems and production outages
  • Network Security - Configuring security groups, VPN access, CORS policies, and network infrastructure
  • Database Operations - SQL Server migrations, RDS management, and database infrastructure optimization

Tech Stack

My hands-on experience includes:

  • Cloud Platforms: AWS Organizations (multi-account structures), AWS (RDS, EC2, S3, CloudFront, Lambda, WAF, IAM, KMS, VPC, Security Groups), Azure (ADO, App Service, Functions)
  • Infrastructure as Code: Terraform (cross-account deployments), AWS SAM (serverless applications), multi-environment infrastructure provisioning, Azure Resource Manager
  • CI/CD: Azure DevOps Pipelines, GitLab CI/CD, automated deployment workflows
  • Containerization: Docker, Elastic Container Service , Kubernetes (AKS)
  • Security & Identity: AWS WAF, AWS IAM, Identity Center (SSO), KMS encryption, SailPoint enterprise integration, certificate management, multi-account security policies
  • Database Technologies: SQL Server, RDS management, database migrations and optimization
  • Networking: VPN configurations, CORS policies, security group management, FortiSASE integration
  • Development: .NET applications, PowerShell automation, infrastructure scripting, Python scripting

Why I Write

I write about the stuff I’m working on and problems I’ve solved. You’ll find:

  • Step-by-step tutorials for real-world DevOps challenges
  • Architecture deep-dives with practical examples and code
  • Cost optimization strategies for cloud infrastructure
  • Lessons learned from production deployments and incidents
  • Tool comparisons and recommendations
  • Personal Projects - I often share my personal projects and how I built them

My Philosophy

I’m big on Infrastructure as Code and automation over manual processes. If I can script it, I will. Every post includes working code that I’ve actually tested.
