I build digital experiences that actually work

Barrel files — those index.ts files that re-export everything in a folder for cleaner imports — are everywhere in my projects, but I'd read they carry a performance cost. So I built a Next.js 15 experiment with 100 components and measured the bundle across wildcard exports, named exports, and direct imports. This article walks through the data, the 'barrel tax' I found on both the client and server bundles, and why module resolution makes it happen.

Inspired by an experiment that synced particle visualizations across separate browser windows, I dug into how tabs can actually talk to each other. I'd previously decoupled a feature so actions in one window were reflected in another — handy for people working across dual monitors. In this article, I explain the Broadcast Channel API and how to use it to share state across tabs and windows cleanly.

While building Contentstack Academy, we made some decisions to improve the overall developer experience of our backend. Many relate to strongly typing our codebase to avoid second-guessing and improve autocomplete, linting, and syntax highlighting. In this article, I wrote about how our configuration module evolved, from adding types to the environment variables to writing JSON schemas, ensuring its use is less error-prone.

I was learning about web standards and discovered the AbortController API. Many SDKs and APIs implement AbortController to simplify their actions. I wrote about how it works, how it can be used to cancel post-message requests, and how I implemented it in my Advanced Post Message SDK.
