How I Built a Real-Time AI Stadium Intelligence Platform Using Only Prompts — PromptWars Virtual 2026

The ProblemEvery IPL match day, 33,000+ fans pack into stadiums with zero real-time intelligence. Staff coordinate manually via WhatsApp. Wait times at food courts are pure guesswork, and crowd surges go completely undetected until panic sets in. After the RCB stampede tragedy that killed 11 fans during their IPL title celebrations, I realized modern Indian stadiums are operating blindly. There is no single screen showing where crowds are building. No early warning when a queue crosses 20

Feature-Based Architecture in React: A Structure That Scales Without Turning Into Chaos

TL;DRThe classic components/hooks/utils structure often breaks down as the codebase and team growFeature-based architecture organizes code by domain responsibility, not by technical typeEach feature should expose a small public API, while keeping implementation details internalA lightweight features/core/ layer can hold reusable domain-aware slices shared across featuresFull features should stay isolated from sibling featuresThe key rule is simple: avoid deep imports and keep dependency di

Day 55: Single Table Design for User Profiles in DynamoDB

Hardcoding variables is a developer habit. Building user configuration is a Product mindset. 🛠️Up until today, my Serverless AI Financial Agent suffered from the classic "Minimum Viable Product" disease: hardcoded assumptions. The AI assumed a fixed €15 daily budget for everyone to maintain their savings streak, and it lazily parsed usernames directly from their Cognito JWT Token emails (e.g., turning [email protected] into "Ericridri11"). It worked for a proof of concept, but as a user expe

30-Day Cloud & DevOps Challenge: Day 6 — Dockerizing My React Frontend

Yesterday, I packaged my backend into a Docker container. Today, I did the same for my React frontend.But there's a twist, frontend containers are DIFFERENT. No Node.js running. No npm start. Just pure, static files served by nginx.And I learned why nginx is the king of web servers.

From a Calorie Counter Prompt to a Local-First Nutrition Tracker

One of the things I’ve been trying to do lately is take project prompts seriously enough to turn them into public, polished repositories instead of leaving them as half-finished exercises.That’s exactly what happened with NutraFlux:https://github.com/johnnylemonny/NutraFluxThe project was inspired by the Calorie Counter idea from the App Ideas repository, but I didn’t want to stop at “search foods and show calories.”I wanted to push it into something that felt faster, cleaner, and more product-l

Advanced Use of Weak References in Memory Management

Advanced Use of Weak References in Memory Management IntroductionMemory management is a critical aspect of developing performant, sustainable applications, especially in environments like JavaScript where garbage collection is automated. As applications grow in complexity, so do the challenges around efficient memory use and prevention of memory leaks. One mechanism within JavaScript that plays a fundamental role in managing memory is the concept of weak references. This article delve

I Built a Side-by-Side Base64 / URL / HTML / Encoder and Finally Stopped Confusing Them

I Built a Side-by-Side Base64 / URL / HTML / Encoder and Finally Stopped Confusing ThemThere are only four text encoding schemes you run into daily on the web. And yet the moment you feed them anything beyond ASCII, each one starts behaving differently. The only way to internalize the differences, I found, is to see all four results next to each other."Is this supposed to be Base64 or URL-encoded?" "Why is 'あ' three bytes in the URL?" "Wait, is it \u{1f389} or \u1f389 for 🎉?" I kept hittin

Running AI in the Browser with Gemma 4 (No API, No Server)

Most “AI apps” today are just API wrappers.That’s fine… until you care about latency, cost, or privacy.I’ve been exploring what it actually takes to run LLMs inside the browser, and Gemma 4 completely changes what’s possible.This is not theory this is what actually works. Why Gemma 4 is differentGemma 4 isn’t just another model release.It’s designed for: • on-device inference • agentic workflows • multimodal tasks (text, audio, vision)The important part?👉 The E2B / E4B variants ar

How I use Claude Code to refactor legacy code — without breaking production

How I use Claude Code to refactor legacy code — without breaking productionLegacy code refactoring is one of the most dangerous things a developer can do. You're changing code that works (somehow) without fully understanding why. One wrong move and production breaks.Here's my exact workflow using Claude Code that's let me safely refactor 50,000+ line legacy codebases. The problem with legacy refactoringLegacy code is scary because:No tests (or tests that don't actually test anything)N

Move From Vite To Ionify

If you are a Frontend developer. Moving from Vite to Ionify is moving from repeating tool work and plugin hooks to Engine with a memory and no plugin hooks!Try Ionify now, and I am totally sure you will not be able to reverse from Engine to tools again!It's not about performance only! It's moving from a tool mindset to an engine mindset!at Ionify: If the file content changes, the moduleHash changes, so the new transformed output goes to a new CAS path. The old one can still physically exist on d

Why I'd pick Tailwind over Unocss in 2026

Frontend tooling has a half-life of about 18 months. By the time the community settles on a best practice, three alternatives have already shipped. Here's where things stand right now. Tailwind vs UnocssTailwind is the industry standard for a reason, but UnoCSS's on-demand approach is tempting. Here's why you'll probably stick with Tailwind.My pick: Tailwind.Tailwind's ecosystem is unbeatable. UnoCSS is clever, but you'll spend more time fighting its limitations than building features.That

Stop Adding Components for Everything — Try This Instead (Vue)

Most Vue libraries solve problems with more components.Need a loader? → add a componentNeed selection? → wrap everythingNeed scroll tracking? → install a plugin + wire stateAfter a while, your UI becomes a tree of wrappers and glue code.💡 What if behavior didn’t need components?I’ve been experimenting with a different approach:👉 using directives as a behavior layerInstead of adding structure, you attach behavior directly to elements.⚡ ExampleNo wrappers. No extra components. No layout changes.🧠
