Building a Loyalty Rewards Engine from Scratch: A Complete Developer Guide

Today, customers expect personalized rewards, real-time point updates, gamified experiences, and seamless redemption across multiple platforms. Behind every successful rewards program is a well-designed loyalty rewards engine capable of handling millions of transactions efficiently. Whether you're a developer building a rewards platform, a startup validating a new product, or an enterprise modernizing its cu

Looking for people to test my behavior ui driven package Nagare

Hey everyone! I've been building a frontend library focused on UI behaviors called Nagare (流れ), and I'd really appreciate some honest feedback from other developers. The idea is simple: instead of splitting a single interaction across CSS, Tailwind classes, event handlers, animation libraries, and state management, everything for that interaction lives in one place. Example: soul("button") border-radius: 20px, border-radius: 12px Each behavior (hover, click, tap, longpress, swipe, drag, scroll,

What Is fetchpriority="high" and Who Should Use It ?

If you've ever analyzed your website with Lighthouse or PageSpeed Insights, you've probably come across a recommendation similar to this: fetchpriority="high" The first time I saw this warning, I was confused. The website was already well optimized. It was running LiteSpeed Cache, images were compressed, WebP was enabled, lazy loading was configured correctly, Critical CSS was working, and LiteSpeed was even generating preload tags for my hero image. So why was Lighthouse still complaining? This

Single Dose of Frog-Derived Gut Bacterium Eradicates 100% of Tumors in Mice

I built "Github for Knowledge" so that Knowledge evolves like Code!

And I'm not talking about another course hosting site. Right now, you're probably in one of these situations: The Researcher: The Educator: The Developer: The Consultant: What if instead, all of that became your revenue stream? Not a hustle. Not a side project. A real business. It's a platform where: You build a creator profile. Not just a username. A real identity. Custom branding. Your colors. Your voice. Your reputation system.

React Performance Optimization: From 3s to 0.8s Load Time

React Performance Optimization: From 3s to 0.8s Load Time I spent three weeks last month staring at a waterfall chart wondering why our CitizenApp dashboard was taking 3+ seconds to load on 4G. The browser was doing something, but what? Turns out, I was shipping 280KB of JavaScript that users didn't need on the first page. This is the story of how we cut that by 85%. Before optimizing anything, I profiled. This burned me once before—I optimized the wrong thing and saved 0.3s on a 50ms bottle nec

Launching TOK: A 3D Interactive Tree of Knowledge Mapping Human Science (R3F + D3-Force)

Hey developers!🚀 I just deployed Tree of Knowledge (TOK), a live production-ready interactive 3D node map built to visually trace the entire macro-lineage of human science. It maps how foundational "father" concepts branched over millennia into today's complex "son" breakthroughs. Check it out live: Website 🛠️ The Tech Stack We built this interactive canvas using a high-performance frontend pipeline: Vite, React.js, React Three Fiber (R3F), custom D3-force spatial physics, Tailwind CSS, and Fr

I Built an AI Job Board Processing 10K+ Listings Daily Here's the Real Architecture

The problem wasn't building it. It was keeping the costs from eating us alive. A job board that scores every listing with GPT-4 is a straightforward technical problem. You fetch listings, pipe them through an LLM, filter by relevance, serve the results. Easy. But when you're doing that for 10,000+ fresh listings every single day, the naive approach will burn through your OpenAI budget in a week. That's a real constraint I had to design around for a client's production platform. Here's the archit

How I stream Mux video from Sanity to Next.js with signed HLS playback

Sanity Mux video playback in Next.js is where most tutorials stop short. The upload side — pushing a file to Mux via Sanity Studio — is well documented. What I rarely see covered is the read path: pulling a stored Mux asset reference out of Sanity, generating a signed playback URL, initialising hls.js in a React component, and making sure the poster frame does not wreck your LCP score. This post covers exactly that. The sanity-plugin-mux-input plugin writes a mux.video asset object into your doc
