Here's How to Fix It Before It Does. · 6 min Lessons from splitting a 4000-resource Terraform state into something teams can work with: state layout, module boundaries, and workflow discipline. infrastructure-as-code infrastructure devops Internal Platforms vs. Ad-Hoc Tooling: Which Developer Experience Actually Wins · 6 min Purpose-built internal platforms versus the organic tooling teams build for themselves -- and when each approach actually delivers. developer-experience platform-engineering devops Your Incident Response Plan Is Useless Until Someone Bleeds · 7 min Most incident response plans are shelf-ware. What actually matters when your infrastructure is on fire, drawn from real breaches and national cyber-defense exercises. security incident-management devops Your Internal Platform Is Probably a Liability · 3 min Most internal developer platforms fail because nobody treated them like a product. Lessons from building (and scrapping) platform tooling at three startups. platform-engineering devops developer-experience GitOps: Stop SSHing Into Production · 9 min How I moved three teams off ad-hoc kubectl deployments and onto Git-driven infrastructure -- with code examples, repo layouts, and the mistakes I made along the way. ci-cd devops kubernetes The Boring Kubernetes Checklist That Actually Keeps Production Alive · 5 min Most Kubernetes outages come from skipping the basics. Here's the checklist I use after running clusters at the fintech startup and now at Decloud. kubernetes devops infrastructure IaC Patterns That Actually Work · 4 min Opinionated Terraform patterns from the fintech startup: repo layout, modules, state management, and what burns you if you ignore it. infrastructure infrastructure-as-code devops Container Security in 2018: What Actually Changed · 3 min Eight months after my first container security post: what moved at the fintech startup and in the ecosystem — PodSecurityPolicy, image signing, scratch images. security containers kubernetes Why Monitoring Wasn't Enough and How We Built Observability at a Fintech Startup · 5 min After a mystery outage that our dashboards couldn't explain, I rebuilt the fintech startup's telemetry stack around metrics, logs, and traces.
