I work directly on live Linux server incidents — from compromised systems and malware infections to high CPU usage, service crashes, and production outages. My focus is fast diagnosis, controlled recovery, and long-term hardening.

The Glue Code Problem If you run Terraform and Ansible together, you know the tax: custom scripts, CLI wrappers, and brittle glue code whose only job is keeping the two tools in sync. It breaks during upgrades, it's a pain to maintain, and it creates governance gaps because

The Feature That Sat Unused for a Decade Worktrees are the latest hotness in git. Which is funny, because they've been around since 2015. They're useful, though, and you might be wondering why you'd use them, how they differ from branches, and why they&

Why Container Security Tooling Needs Its Own Evaluation Framework Container adoption keeps outpacing security maturity in most organizations. Traditional endpoint protection was never designed for ephemeral, highly dynamic containerized environments, and it often fails to provide the visibility these workloads demand—agents assume persistent endpoints with stable operating systems, and
AI Security
The Backlog Problem AWS Is Trying to Solve On June 17, 2026, at its New York Summit, AWS launched Continuum—a security platform that uses frontier AI models to discover, validate, and remediate software vulnerabilities across a customer's environment with limited human intervention. Continuum for code vulnerabilities, the

The Pipeline Image That Got Out of Hand I took over an existing Kubeflow pipeline from another ML engineer. First thing I checked: image size. 3.17 GB. The DevOps team agreed that was unacceptable for a pipeline running on every model retrain. The goals were simple: reduce the size

The Few Seconds the User Sees, the Millions of Transactions They Don't Every day, millions of people order food, stream videos, send messages, book rides, make payments, and shop online. From the user's perspective, each action takes a few seconds. Click a button, get a response,
Cloud Security
You Don't Have a Tooling Problem. You Have a Mapping Problem. Most cloud security teams already own too many tools. Yet misconfigured storage, excessive permissions, vulnerable workloads, and exposed Kubernetes services still create exploitable attack paths. The problem isn't a lack of tooling. It's

The Default That Caused Years of Supply Chain Attacks Is Finally Changing With npm v12, dependency preinstall, install, and postinstall scripts will no longer execute automatically during package installation. Script execution will require explicit approval through new controls like npm approve-scripts. The change is expected to arrive in July

A Model Vanished for Everyone, in Hours On the evening of June 12, 2026, Anthropic disabled access to two of its newest models—Claude Fable 5 and Claude Mythos 5—for every customer worldwide. Not because of an outage or a self-discovered flaw. To comply with a US government

The Scaling Problem Nobody Sees Coming Your first scaling problem rarely arrives with a bang. For a while, everything works: pages load fast, the database barely breaks a sweat, and the team ships features without thinking about infrastructure. Then traffic climbs. A campaign over-performs. A marketplace onboards a popular

The 2 AM Debugging Mystery: df Says 80% Full, du Says 50% You're debugging a full disk alert. The df command shows red. The du / output looks totally fine. You run both commands three times, thinking you misread something. The numbers don't match. One of them

Controls Without Context Don't Work Container security programs lose effectiveness when controls are implemented without connecting them to specific attack outcomes. Running a container as root increases the impact of a container escape. Non-root execution reduces what an attacker can do with that foothold. The control only
