A dashboard I worked on became slower over time. At first, we blamed the backend. It wasn’t the backend. Here’s what was happening 👇 Problem: → UI lag after filters → Slow rendering with large datasets Root cause: → Uncontrolled re-renders → Large lists rendered fully → Expensive computations repeated What I did: → Controlled render flow → Introduced list virtualization → Optimized heavy calculations Result: → Smooth UI → Faster interactions → Better UX Insight: Performance issues are rarely one big problem. They’re small inefficiencies at scale. #ReactJS #Performance #Frontend #SoftwareEngineering #CaseStudy #JavaScript #WebDevelopment #Engineering #Optimization #FrontendDeveloper

The "Future of Interfaces" just dropped. 🚀 Ex-React core dev Cheng Lou spent years "crawling through the depths of hell" to solve the web's oldest bottleneck: text measurement. Pretext (released 4 days ago) is a pure TypeScript algorithm that lets you layout entire pages without CSS or the DOM. 🔥 Bypass the DOM: Zero layout reflows and zero expensive DOM measurements. 🎯 Perfect Accuracy: Fast, comprehensive measurement for every language. 🏗️ Infrastructure Level: Render to Canvas, SVG, or Server-side with ease. 🤖 AI-Optimized: The foundational logic needed for next-gen agentic UIs. This isn't just a library—it’s the new foundation for high-performance UI engineering. GitHub: https://lnkd.in/dbxQpP4x #WebPerf #SoftwareEngineering #TypeScript #Innovation #Frontend #OpenSource

I’m excited to share a project I built: Interactive Globe Search Interface. It is a research-oriented web application designed for multi-region search, historical web exploration, and analytical visualization. The platform allows users to explore search behavior from different geographic perspectives, compare live results with archived evidence, and analyze findings through a more interactive and visual workflow. Some of the capabilities included in this project: - Geographic search exploration through an interactive globe interface - Live result aggregation with structured filtering - Historical discovery using archived web captures - Timeline and analytical views for better interpretation of results - A frontend and backend workflow focused on experimentation, research, and technical validation Built with React, TypeScript, Vite, Tailwind CSS, and a backend designed for structured search and archive analysis. Live demo: https://lnkd.in/eDtZBfFu This project was a great exercise in combining UI engineering, search workflows, data interpretation, and full-stack integration into a single platform. #WebDevelopment #FullStack #React #TypeScript #Frontend #Backend #DataVisualization #SoftwareDevelopment #ResearchTools #PortfolioProject

Are you using RxJS the right way? 🤔 In frontend development, there are 4 key operators for handling async requests: switchMap – mergeMap – concatMap – exhaustMap Let’s break it down with a simple example 👇 Imagine you have a search box 🎬 Every time the user types, you send a request to fetch movies Here’s the difference: 🔁 switchMap Cancels the previous request and only keeps the latest one 👉 Best choice for search ⚡ mergeMap Runs all requests in parallel 👉 Can lead to messy results and performance issues 📋 concatMap Queues requests and runs them one after another 👉 Useful when order matters 🚫 exhaustMap Ignores new requests until the current one is done 👉 Great for preventing spam clicks 💡 Takeaway: Choosing the right operator = better UX + better performance #Angular #RxJS #Frontend #WebDevelopment

ebsite has buttons… but do they actually respond? Clicks happen. Keys are pressed. Forms get submitted. But nothing meaningful happens. That’s where most beginners get stuck. Then the real problems start: No real interaction. Poor user experience. Static feel websites. Missed user actions. In 2026, JavaScript isn’t just about logic. It’s about reacting to user behavior in real time. Events help you: • Handle clicks, inputs, and actions • Trigger functions on user interaction • Build dynamic and responsive UI • Improve user engagement • Create real-world web experiences Because users don’t just see your website — they interact with it. So ask yourself — is your site listening to users? #JavaScript #WebDevelopment #FrontendDevelopment #Events #Coding #UIUX #DeveloperLife #LearnToCode

Why is asking a browser “how tall is this text?” still expensive in 2026? Because the moment you ask: How tall is this text? the browser often triggers a layout reflow. And reflow is one of the most expensive things the rendering engine can do. It can force recalculation across large parts of the page just to answer a simple measurement request. That is exactly why Pretext is getting so much attention. Created by Cheng Lou, former React core team member and Midjourney engineer, it is a TypeScript library that measures multiline text without touching the DOM. No offsetHeight   No getBoundingClientRect()   No forced layout work  Instead, text is prepared once, measured once, and then laid out using pure arithmetic. That sounds subtle. But it changes what becomes practical in frontend systems: • virtualized chat feeds with unpredictable message sizes   • stable infinite lists   • masonry layouts without guessing heights   • less layout shift during async rendering  --- Technical detail 👇 The browser still provides font truth through canvas width measurement. But line breaking is handled independently. That means Pretext reproduces rules for: • whitespace collapsing   • grapheme segmentation   • bidirectional text   • language-aware wrapping  The important split is: prepare() → expensive once   layout() → cheap many times  So resizing no longer means measuring everything again. Benchmarks already show: • prepare() ~19ms for 500 texts   • layout() ~0.09ms for the same batch  And that is the deeper engineering lesson: sometimes performance improves not by rendering less, but by asking the browser fewer expensive questions.

WebAssembly is no longer just a “cool browser tech” — it’s becoming a serious tool for building compute-heavy web apps that actually perform well. Where it really shines is when JavaScript starts to hit limits on raw performance. Real-world use cases I’m seeing: • Video and audio processing in the browser • Image editing and compression tools • CAD, 3D modeling, and visualization apps • Scientific simulations and data analysis • Games and physics engines • Running existing C/C++/Rust libraries on the web • On-device AI inference with lower latency Why teams are adopting it: • Near-native performance for CPU-intensive workloads • Reuse of proven native codebases • Better responsiveness for complex browser apps • More work done client-side, reducing server costs • Strong fit for privacy-sensitive processing because data can stay on-device Important nuance: WebAssembly is not a replacement for JavaScript. It’s best used selectively — for the hot paths where performance matters most — while JavaScript or TypeScript still handles the broader app experience. The big shift is this: The browser is no longer just a UI layer. It’s increasingly a serious runtime for high-performance software. If you’re building web apps that need desktop-like performance, WebAssembly is worth a close look. #WebAssembly #WebDevelopment #Performance #JavaScript #Rust #Frontend #SoftwareEngineering #WebApps Summary: Wrote a LinkedIn post on WebAssembly for compute-heavy web apps with practical use cases and positioning. #WebDevelopment #TypeScript #Frontend #JavaScript

The web in 2026 feels faster, smarter, and more “alive” than ever. AI tools are now true partners in scaffolding UIs and debugging edge cases, meta-frameworks like Next.js have become the default for shipping performant apps at the edge, and the focus has shifted from just building pixels to crafting intentional, high-performance user experiences. Over the past few months, I’ve been diving deeper into: Leveraging AI for rapid prototyping while keeping full control over accessibility and Core Web Vitals. Optimizing for server-first rendering and edge computing. Building cleaner, more maintainable component architectures with TypeScript and modern tooling. One quick lesson that stuck with me: the real differentiator isn’t knowing every new library, it’s knowing when (and why) to use them to solve actual user problems. If you’re a fellow front-end dev, designer, or product person: What’s one trend or tool that’s genuinely changed how you build in the last year? Or what challenge are you wrestling with right now in modern web development? Drop it in the comments, I’d love to learn from you and reconnect.

I recently developed a project called DigiTool using React, Tailwind CSS, and DaisyUI. I structured the project using React components to keep the code clean and organized. The UI was designed with Tailwind CSS (Flexbox & Grid) and DaisyUI for elements like the navbar and cards. I created JSON data (with AI), hosted images using imgbb, and fetched the data to display products dynamically using map(). I implemented a cart system with features like add, remove, and checkout using state management. I also used toggle functionality to switch between product and cart views, and applied filter() and ternary operators to make the UI dynamic. To enhance user experience, I integrated React Toastify for notifications like add to cart, remove, payment successful, and already added. The entire application is fully responsive across all devices. This project helped me strengthen my React fundamentals and build a complete interactive UI.
