The Claude Tag Session That Survived a Reinstall

One channel's Claude in Slack session pinned a six-day-old connector config and silently ignored every change after it. Removing and reinstalling the app didn't touch it. The rollout turned into a security rebuild.

The Way of Code Against Production

Rick Rubin rewrote the Tao Te Ching as vibe-coding aphorisms. Some of it maps cleanly to how I build. Some of it falls apart the moment a pager goes off.

Even the People Who Build Claude Code Got Lonely

Anthropic's own engineering lead said Claude Code made her team lonely. We spent two years measuring what agents do to velocity and cost, and nobody costed out what they do to the room.

GitHub Copilot Became a Meter Running in My Editor

My annual Copilot Pro+ subscription ended right as GitHub switched from Premium Request Units to usage-based AI Credits. GitHub's own preview repriced my April from $147.38 to $1,297.49.

I Stopped Rebuilding the Same System

Over ten years, my projects kept turning into the same backend, infrastructure, tenancy, auth, deployment, and validation. I stopped treating those as fresh decisions for every product and pulled them into one reusable system.

Renaming a GitHub Repo Silently Breaks AWS CodeBuild

Renamed a GitHub repo. Pushed multiple commits. Nothing deployed. No errors anywhere. Turns out CodeBuild doesn't follow GitHub's repo redirects, and the webhook linkage breaks without telling you.

Google Analytics Was Measuring the Wrong Thing

Google Analytics tracked page views in a product where page views don't matter. I replaced it with internal event tracking and Cloudflare, and finally saw how the system actually behaves.

Building an Email-Driven Multi-Tenant Ingestion Pipeline

Most write interfaces are HTTP forms posting JSON. For Lush Aural Treats, submissions enter through email. Here's the architecture behind a tenant-aware ingestion pipeline where the inbox is the API.

How a $1,000 AWS Bill Made Me Redesign My ECS Architecture

I deployed a standard ECS architecture for Lush Aural Treats and didn't watch the bill. NAT gateways and ALBs quietly ate $1,000. Here's how I redesigned the whole thing to cost almost nothing.

Beyond Vibe Coding: Using AI as an Engineering Collaborator

Most AI dev content is about vibe coding or tool comparisons. Here's the structured workflow I've been using across real projects, and why it actually works.

Prompt Engineering for AI Music: What Actually Works with Suno

The prompts that look the most detailed rarely produce the best music. Music models respond to production primitives like drum patterns, instrumentation, and arrangement structure. Not adjectives.

Automating the $100 of AWS Credits Available to New Accounts

New AWS accounts get $100 in credits for completing five Explore activities. Four of them can be fully automated with Terraform. Here's how.

Silicon Valley's New Religion

The people shaping AI don't just think they're building tools. They think they're building gods.

Survive. Adapt. Keep moving.

Joey Bada$$'s Dark Aura hits different when you've been through the chaos of tech. The layoffs, the uncertainty, the late-night coding sprints with no safety net.

Reality Is Contested

As generative AI improves, the line between truth and fabrication dissolves. The future isn't just about better tools. It's about living in a world where reality itself is contested.

I paid $400 NZD for a year of Claude Pro. Here's what I got, and why GitHub Copilot is worth every cent.
