Explore case study ↗About / Approach
From architectural decisions to running code.
My work connects long-term engineering design with practical delivery: breaking down shared dependencies, making Terraform modules reusable, enabling developers with repeatable security checks and designing cloud-native monitoring pipelines.
I enjoy the hard problems that sit between infrastructure, reliability and security—and solutions that other teams can actually use.
Cloud & infrastructure
AWS Organizations, IAM, networking, CloudTrail, EC2, Lambda, S3 and platform architecture.
Infrastructure as Code
Terraform, reusable modules, versioning, JFrog Artifactory and automation with Python.
Secure delivery
GitHub Actions, Buildkite, Checkov, Gitleaks, TFLint, security gates and container tooling.
Telemetry & operations
Dynatrace, CloudWatch, Microsoft Sentinel, SQS, operational visibility and incident support.
