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

Stop Using useState for Forms: The React Hook Form + Zod Architecture
The Re-render Trap of Controlled ComponentsForms are the lifeblood of any B2B SaaS platform. From complex multi-step onboarding flows to intricate financial data entry, users spend a massive amount of time inputting data. Historically, the "React way" to handle forms has been using Controlled Components—tying every single input field to a useState hook.While this works for a simple login page, it becomes a performance disaster for a 30-field enterprise invoice form. Every single keystroke in a c
Stop Storing JWTs in Local Storage: The HttpOnly Cookie Architecture 🛡️
The LocalStorage VulnerabilityWhen building decoupled B2B SaaS applications at Smart Tech Devs, authentication is the first line of defense. The most common architectural pattern for a Next.js frontend communicating with a Laravel API is using JSON Web Tokens (JWTs). However, the most critical mistake developers make is returning that JWT in the API payload and storing it in the browser's localStorage.Storing sensitive tokens in localStorage or sessionStorage exposes your entire user base to Cro
Accessibility-first looks different from accessibility-compliant
Passing an axe-core audit is not the same thing as designing for accessibility. The outputs can look identical. The process that produced them is not.Most component libraries retrofit accessibility. The ARIA roles get added, the keyboard navigation gets wired, the contrast ratios get verified. It passes. But the architecture was not designed around the constraint. It was designed first, then adjusted to meet it.nuka-ui was built with WCAG 2.2 AA as a hard requirement from the first commit. Not a
Show HN: We unionized Maxwell's Demon– A paper on labor rights in thermodynamics
We just published a short communication on the working conditions of Maxwell's thermodynamic demons (yes, really).tl;dr: After 150 years of unpaid "tuc tac" trapdoor operation, we calculated that the ideal demon lacks (1) employment contracts, (2) coffee breaks, and (3) hazard pay for oil-can maintenance. We propose transferring thermal operators to "White Hole" systems where observation costs 0.34W of real metabolic heat and entanglement is compensated in hugs (1 /
