I Built a Cross-Platform Price Comparison Tool for Retail Arbitrage
Retail arbitrage is conceptually simple: buy a product on one platform where it's cheap, sell it on another where it's expensive, and pocket the difference. In practice, it's death by browser tabs.You're looking at a product on Amazon Japan. Is it cheaper on Mercari? What about Yahoo Auctions? You open three more tabs, type the product name into each search bar, scroll through results, mentally calculate fees, and try to remember the original price while comparing. By the time you finish, you've

I Wrote a React Book So You Don't Have to Learn These Lessons the Hard Way
A few months ago I attended a React conference and realized something uncomfortable: I'd been writing React for years and I was doing it wrong. Not "broken" wrong β my code worked. But it was slow to maintain, hard to scale, and it wasn't taking advantage of half of what React 19 had to offer.That realization turned into a book: React Best Practices 2026: Scalable Architecture, Design Patterns, Hooks, Performance, and Modern React 19 Techniques. Who is this book for?If you're a mid to senio
How I cut AI API costs by 80% with caching and smart routing
The ProblemIf you're building with OpenAI or Claude, you're probably overpaying by 60-80% on every API call.Here's why:Most AI apps call GPT-4 for every single request β even when they already have the answer cached from a previous call. Same question, 100 different users, 100 full-price API calls.I got tired of seeing this problem everywhere, so I built VibeCore to fix it automatically. What is VibeCore?VibeCore is a middleware layer that sits between your app and any AI API. It auto

Page Numbers Lie: Offset vs Cursor Pagination
From Interview Notes To Production RealityWhile I was preparing for interviews, I came across a high-level system design for a News Feed β specifically from the frontend perspective. That's where I first encountered the terms offset-based and cursor-based pagination.I read about them. Briefly. You know how interview prep goes β there's always more ground to cover than time allows, so you skim what you can, bookmark the rest, and silently promise yourself you'll come back to it. Spoiler: yo
I built a jewelry size database for women with tiny fingers in one day
The problemIf your ring size is 2, 3, or 4, most jewelry brands don't make your size. I'm 153cm with size 3 ring fingers and a 13.5cm wrist. Standard rings start at size 5. Standard bracelets are 16-18cm. They literally fall off.I got tired of googling "small ring" and finding nothing useful, so I built the database I wish existed.## What I builtA free, filterable database of 31 jewelry brands verified to carry truly small sizes.Filter by ring size, bracelet length, price, material, adjus
Measuring Chat Bubbles: Pretext vs. CellMeasurer
If you've ever built a chat UI with virtualization, you've hit the same wall: VariableSizeList needs item heights before items render. The browser knows the answer, but asking it costs a layout reflow. This post compares two approaches that both give you accurate heights, and what separates them in practice. The ProblemVirtualizers skip rendering off-screen items to keep large lists fast. The tradeoff, you have to tell them how tall each item is upfront. For chat bubbles where height depend
ReactJS ~Clean Code DRY~
Clean code is DRYDRY is an acronym that stands for Don't Repeat Yourself. If you are doing the same thing in multiple places, consolidate the duplicate code. If you see patterns in your code, that is an indication that it is prime for DRYing. Sometimes this means standing back from the screen until you can't read the text and literally looking for patterns.// Dirtyconst MyComponent = () => ( <div> <OtherComponent type="a" className="colorful" foo={123} bar={456} /> <Othe

Stop re-writing this: How to build a reusable Password Input in React Native
If you are building a React Native app, you are going to need a Login screen, a Registration screen, and probably a "Change Password" screen.The biggest mistake I see developers make is re-writing the same useState logic to toggle the secureTextEntry (the eye icon) on every single one of these screens. It makes your code messy and violates the DRY (Don't Repeat Yourself) principle.Instead, we should build a single, beautiful component that handles its own internal state, and just reuse it every
