What Happens When You Give Your Best Engineer an AI Team

A compliance gap that required weeks of cross-ecosystem investigation was closed in a day. What that means for how engineering leaders should think about staffing and delivery.

I Have Zero UX Sense. So I Let Claude Code Design the Site.

How I built and designed gitrdun.net entirely with Claude Code — Bauhaus system, scrolling ticker, Playwright test suite, and the embarrassing truth about my design instincts.

Bad Information Is the Most Expensive Thing You're Not Tracking

An afternoon's investment. Permanent research capacity. What it means when your team stops operating on best-guess findings.

What a Verified Research Process Actually Looks Like

The same problem, the same system — explained for the people who own the work, not the people who built the plumbing.

AWS Config Aggregators don't track deleted resources

Config Aggregators give you a centralized view of live resources across your org. Deleted resources vanish from that view entirely. Here's what actually works for deletion tracking.

investiGATOR: VPC Flow Log analysis that doesn't require manual correlation

A Python tool with CLI and web interfaces for analyzing VPC Flow Logs — SSH brute force detection, data exfiltration monitoring, sensitive port analysis, and WHOIS-enriched external traffic — with automatic AWS resource discovery.

One SCP that prevents accidental KMS key deletion

The default KMS deletion window is 7 days. A developer running a cleanup script on Friday afternoon leaves the production team 3 days to catch it. Here's the SCP that enforces a 30-day minimum.
