Not theoretical, not projected, not “emerging.” Real. I use Claude, GPT, and Gemini daily in my platform engineering work, and the output multiplier is staggering. Tasks that used to take me a full afternoon now take twenty minutes. Architecture documents, Terraform modules, debugging complex Aurora PostgreSQL cluster issues, writing RFCs. The leverage is unlike anything I’ve experienced in eighteen years of building software.https://dhewy.dev/posts/the-lag-and-why-ai-displacement-numbers-tell-half-the-story/Tue, 24 Feb 2026 14:02:08 +0000https://dhewy.dev/posts/the-lag-and-why-ai-displacement-numbers-tell-half-the-story/There’s a narrative forming that goes something like this: AI is destroying white collar jobs, the economy is crumbling, and we’re all doomed. The numbers look terrifying. Nearly 700,000 job cuts in the first five months of 2025 alone, an 80% jump from the prior year [1]. College graduate unemployment hit 5.8% in March, the highest in over four years, and for the first time in modern history it’s trending above the aggregate rate [2].https://dhewy.dev/posts/running-github-actions-on-your-desk-instead-of-renting-compute/Tue, 24 Feb 2026 10:37:55 +0000https://dhewy.dev/posts/running-github-actions-on-your-desk-instead-of-renting-compute/I had a MacBook Pro M1 and a Raspberry Pi 4B sitting on my desk doing nothing. I also had a GitHub Actions bill I didn’t want. Small bill. Annoying bill. The kind that makes you think “I have perfectly good compute right here.” So I stopped renting and started running self-hosted GitHub Actions runners on desk hardware. Spare kit, Docker containers, zero monthly cost. Here’s how it went. What GitHub Actions Actually Costs You GitHub gives you 2,000 free minutes per month on the Free plan for private repos.https://dhewy.dev/posts/every-employee-gets-an-ai-team.-now-do-the-maths/Tue, 17 Feb 2026 14:59:47 +0000https://dhewy.dev/posts/every-employee-gets-an-ai-team.-now-do-the-maths/Give every employee 5-9 AI agents and the org chart explodes. Here’s what maximum augmentation actually looks like, and why the ceiling is lower than you think. In the previous post, I argued that the span of control problem applies to AI agents just as much as it applies to people. A single human can effectively oversee somewhere between five and nine direct reports before quality degrades. Swap “direct reports” for “AI agents” and you hit the same wall.https://dhewy.dev/posts/the-span-of-control-problem-hasnt-gone-anywhere/Mon, 16 Feb 2026 16:45:24 +0000https://dhewy.dev/posts/the-span-of-control-problem-hasnt-gone-anywhere/There’s a persistent fantasy floating around right now that AI coding agents will let a single engineer do the work of ten. Or fifty. Or an entire team. The maths sounds seductive: if one agent can produce code at 10x speed, just spin up five of them and you’ve got a 50x engineer. Ship it 🚀 Except anyone who’s actually managed people knows this logic collapses almost immediately. The manager’s ceiling There’s a concept in organisational theory called “span of control.https://dhewy.dev/posts/the-ai-revolution-and-jevons-paradox-why-the-future-of-tech-jobs-isnt-what-you-think/Tue, 20 Jan 2026 08:34:07 +0000https://dhewy.dev/posts/the-ai-revolution-and-jevons-paradox-why-the-future-of-tech-jobs-isnt-what-you-think/The discourse around AI and employment has become predictably binary. On one side, breathless predictions of mass unemployment. On the other, techno-optimists insisting everything will be fine. Both camps are likely wrong, but not in the way you might expect. A Brief History of Efficiency Panics In 1865, economist William Stanley Jevons observed something counter-intuitive about coal consumption in England. As steam engines became more efficient, requiring less coal per unit of work, total coal consumption didn’t fall.https://dhewy.dev/posts/the-ai-employment-paradox-why-the-job-crisis-narrative-misses-the-point/Thu, 04 Dec 2025 15:02:20 +0000https://dhewy.dev/posts/the-ai-employment-paradox-why-the-job-crisis-narrative-misses-the-point/AI won’t destroy jobs—it will multiply them. But only for those who understand the real opportunity isn’t efficiency, it’s entrepreneurship. The Panic Is Real. The Conclusions Are Wrong. Open any business publication and you’ll find breathless coverage of AI-driven layoffs. Companies are “streamlining operations,” “leveraging automation,” and “right-sizing” their workforces. The subtext is always the same: AI is coming for your job. And to be fair, the disruption is real. The World Economic Forum’s Future of Jobs Report 2025 projects that 92 million jobs will be displaced by 2030.https://dhewy.dev/posts/the-infrastructure-automation-stack-that-actually-scales-terraform-terragrunt-and-atlantis/Wed, 03 Dec 2025 11:54:55 +0000https://dhewy.dev/posts/the-infrastructure-automation-stack-that-actually-scales-terraform-terragrunt-and-atlantis/There’s a point in every platform team’s journey where the basic Terraform setup stops working. Not “stops working” in the sense that it breaks—it just stops scaling with you. You end up with sprawling CI/CD configurations, copy-pasted variable blocks, and that creeping dread every time someone asks “can we spin up another environment?” This post is about moving beyond that. Specifically, it’s about combining Terraform, Terragrunt, and Atlantis into a setup that handles real-world infrastructure complexity without drowning in configuration sprawl.https://dhewy.dev/posts/is-it-time-to-stop-shaming-vibe-coding/Tue, 02 Dec 2025 21:15:21 +0000https://dhewy.dev/posts/is-it-time-to-stop-shaming-vibe-coding/The future isn’t coming. It’s already here—and we need to talk about it honestly. Last month, Adam Wolff—engineer at Anthropic, former Head of Engineering at Robinhood, and one of the people whose work led to React—posted something that made me stop scrolling: “I believe this new model in Claude Code is a glimpse of the future we’re hurtling towards, maybe as soon as the first half of next year: software engineering is done.https://dhewy.dev/posts/how-i-built-this-blog-using-hugo-obsidian-aws-and-claude/Mon, 01 Dec 2025 09:53:15 +0000https://dhewy.dev/posts/how-i-built-this-blog-using-hugo-obsidian-aws-and-claude/It was about time I updated my blog. This post covers building a new blog from start to finish using Hugo, Obsidian (for post editing, optional), AWS S3+Cloudfront with Terraform, and Github Actions for CI/CD. I hope someone finds it useful.

Automation obsessed. Now deep in AI. Before that, I spent 4-5 years building the backend for an online game I co-founded. Nothing teaches you scalability and security like players finding every edge case you missed. Automation is my default. If I have to do something twice, I’ll spend the time to make sure I never have to do it again. These days, I’m focused on AI and how it’s changing the way we build software.https://dhewy.dev/cv/Mon, 01 Jan 0001 00:00:00 +0000https://dhewy.dev/cv/Experience Add your work experience here.
