💡 𝗧𝗶𝗽 𝗼𝗳 𝘁𝗵𝗲 𝗗𝗮𝘆 — 𝗥𝗲𝗮𝗰𝘁 𝗗𝗶𝗱 𝘆𝗼𝘂 𝗸𝗻𝗼𝘄? Every time a parent component re-renders, 𝗮𝗹𝗹 𝗼𝗳 𝗶𝘁𝘀 𝗰𝗵𝗶𝗹𝗱 𝗰𝗼𝗺𝗽𝗼𝗻𝗲𝗻𝘁𝘀 𝗿𝗲-𝗿𝗲𝗻𝗱𝗲𝗿 𝘁𝗼𝗼 by default. Even if the child’s props didn’t change. 🔧 𝗛𝗼𝘄 𝘁𝗼 𝗼𝗽𝘁𝗶𝗺𝗶𝘇𝗲: Wrap pure components with "React.memo" so they only re-render when their props actually change. This small optimization can significantly improve performance in large component trees. Smarter renders = faster UI.

64% of my Claude Design limit. Gone. Before I designed a single screen. 😅 I never start a project without a design system in place - so naturally, the first thing I did was import the full shadcn/ui system straight from the official GitHub repo. Needed some tweaks, but at least I didn't build it from scratch. Still somehow burned through half my limit doing it. 🙃 Can't imagine using it on an actual project with this kind of consumption, but interesting nonetheless.

64% gone before the first screen feels like the most accurate summary of modern workflows.

Built with Paper for the #PaperChallenge.

I designed a series of immersive shader effects in Paper, then used Cursor to implement them as a React site. The concept: vertically stacked chips as site navigation, each one revealing a different animated shader as a full background on hover.

Paper lets designers create WebGL shader effects visually, then exports them directly as React components. Cursor handled the implementation. The whole thing came together on a rainy Sunday afternoon.

This unlocks something real for designers. Complex, performant visual effects that used to require a specialist are now part of the design workflow.

Bravo, Paper.
