Kiro: Spec-driven Development Done Well

At this point software developers have realized Vibe Coding has its ups and downs. It’s amazing for experimentation or proof of concepts. But in the field, it can be more work than was realized. That’s because it can only build what it has seen. AI, once again, is only good at pattern recognition, which covers a wide spectrum of things. “What’s past is prologue.” — William Shakespeare, The Te...

I Built a Neumorphic CSS Library with 77+ Components — Here's What I Learned

What is SoftUI? SoftUI is a neumorphic CSS component library. Instead of flat design or material shadows, everything uses soft, diffused shadows that make elements look like they're gently raised from or pressed into the surface. No React. No Vue. No build step. Just CSS classes and an optional vanilla JS file for interactive components. <link rel="stylesheet" href="https://unpkg...

First Post

I want to get back into writing (okay, blogging), but the challenge I've always had is never having a permanent home for it. Self host? Use a platform? What about ownership? Future paywalls? I used my AI friends to help get to a conclusion - host it on GitHub. No different than Code and I alone determine how my intellectual property is used and by who. The problem is, the workflow around publishi...

I Replaced /usage and /context in Claude Code With a Single Statusline

You already run /usage and /context all day. This bash statusline puts both, plus your 5h reset time and working directory, at the bottom of every Claude Code prompt as colored progress bars. Exact script inside. I'm on Claude Code Max 5x. It's a generous plan. It is also not infinite. Three things kept catching me off guard. The 5-hour session window would fill up in the middle of a long chain ...

Motion: How to combine parent staggerChildren with individual animations when dynamically adding items?

I am building a dynamic list in React with Framer Motion. I want to achieve two goals: When the list initially mounts, the items should animate in sequentially using the parent's staggerChildren. When I dynamically append a new item to the list later, that specific new item should play its own entrance animation. However, I am facing a tough situation with variant propagation: Scenario A: If I...

LLM Evals Are Not Enough: The Missing CI Layer Nobody Talks About

Running LLM evals is not the same as being able to trust them in production release workflows. That is the core argument of this piece. Evals generate useful measurements such as pass rates, groundedness scores, safety findings, and per-test results, but CI/CD systems do not need measurements alone. They need a deterministic answer to a much narrower question: should this build pass or fail? The ...

Everyone's Using AI. No One Agrees How.

I got a DM from a principal engineer last week. He's spending more than $2,000 a month on AI tokens. Not because he's lazy. Because he's figured something out. The tool isn't giving him 10x output. It's giving him exponential output. He's orchestrating agents, chaining workflows, building systems that compound. I know a tech lead who turned his AI license back in. Said he doesn't want to use it. ...
