Most people think @Uniswap v4 innovation is happening in smart contracts. I disagree The next bottleneck is frontend infrastructure A hook can implement brilliant mechanism design, but if users can't understand what the hook is doing, the innovation never reaches the market Building interfaces for custom liquidity behavior, dynamic fees, and protocol-specific state is becoming a new engineering discipline #UniswapV4 #DeFi #FrontendEngineering

Currently building the frontend for Oscillon, a Uniswap v4 hook focused on reducing LVR in stablecoin pools. The interesting part isn't the UI itself it's translating complex protocol mechanics into a product that users can understand, trust, and interact with confidently. Frontend engineering in DeFi is often about making sophisticated systems feel intuitive #UniswapV4 #DeFi #FrontendEngineering #Web3

I Audited 40 React Codebases. Every Single One Had a useEffect Memory Leak. Read the full article here: rgndunes.github.io/Portfolio… #React #JavaScript #WebDevelopment #FrontendEngineering #Performance #MemoryLeaks #SoftwareEngineering

The biggest takeaway: Code that never ships doesn't exist. Three days. ✅ Architecture ✅ Quality ✅ Delivery Now it's time for Build Week. Can't wait to see the projects on Demo Day #GDGFUTO #FrontendEngineering #WebDev #CICD

Key takeaway: A slow app is a broken app. Performance and reliability are features, not afterthoughts. 🔥 Day 3 this evening: Deployment, CI/CD & Production Workflows. #GDGFUTO #FrontendEngineering #WebDev #ReactJS

🏗️ Beyond Checkbox Compliance: Mastering Inclusive Angular Architecture In the 1970s, the "Curb-Cut Effect" proved that designing for disabilities makes life better for everyone. In the digital world, we are the architects of the sidewalk. Are you building "digital barriers" or inclusive paths? In her latest deep dive, Brygida Fiejdasz explores the shift from basic UI labeling to a fundamental design philosophy using the Angular A11y toolkit. What you’ll learn in this masterclass: ♿ The POUR Principles: Perceivable, Operable, Understandable, Robust—the DNA of WCAG 2.2. ♿ Audit Tools: How to use Lighthouse, WAVE, and simulators to see your app through the eyes of every user. ♿ The Angular ARIA Toolkit: Leveraging headless directives for total creative freedom without the "accessibility tax." ♿ CDK A11y Utilities: Mastering FocusTrap, LiveAnnouncer, and FocusMonitor to solve complex "invisible" problems. 🎯 Accessibility isn't a final checklist; it’s a shift in how we build. It's time to ensure our apps are inclusive by design, not by accident. 👉 Clear the path for every user with the full guide: 🔗 f.mtr.cool/pdtvvklpiw #iJSConf #Angular #A11y #WebAccessibility #FrontendEngineering #InclusiveDesign #SoftwareArchitecture

3D Architecture in One View Renderer → scene → pixels Scene Camera → define what exists & what’s seen Hierarchy → Object3D → Mesh → Group → Light Every object =Geometry Material Texture A real-time system running on the GPU. #threejs #webgl #frontendengineering

Three.js isn’t UI — it’s systems. GPU tradeoffs. Draw calls. Scene graphs. Raycasting. This is real-time engineering in the browser. #threejs #webgl #frontendengineering

More dependencies don’t mean more capability. They mean more maintenance. Upgrade cycles. ✓ Breaking changes. ✓ Conflicting APIs. ✓ Sometimes the best architecture decision is simplification. 📷 Comment “INFO” and we’ll send you the full explanation. #JavaScript #FrontendEngineering #ExtJS

Exploring advanced routing patterns: • createBrowserRouter() • Nested routes with <Outlet /> • Dynamic segments (/user/:id) • Route-level data fetching with loaders #WebDevelopment #JavaScript #FrontendEngineering

Your app talks to the network. Service Workers decide how. ⚡ • Intercept requests. • Cache for speed offline. • Control updates & sync in the background. This isn’t “just PWA”. It’s frontend system design. 🚀 #FrontendEngineering #WebPerformance

Today was the Challenge presentation of what we have learnt for the first month of building. We were given a project each to Develop the Website as given in the figma file and also the responsiveness and guess what I cooked as always. I was assigned to develop the Landing Page, Sign in, Signup Page and Dashboard of A Modern Hotel Booking Website, it was challenging but I didn’t anyway and stood up to the challenge and ruled over it as it should be. The judges were impressed with my work and being able to defend the code. I was so happy but it was a sign I’m progressing and getting better in this path chosen. Even though there was a little bit of review, I’m glad I could defend and even got the first applause among others for a job well done and defense well done. Thank you @grazacng your professionalism and Facilitators are amazing and it’s been a great experience from Day one, from challenging my critical thinking to skills and being able to learn more than on my own than what was taught in class. #frontend #frontendengineering #challengepresentation @grazacbackup @VictorAdeleye_

Thanks to Ajith Kumar P M and Aswathy Saji for the session “State Machines: The Last State Management Solution You’ll Ever Need.” ➡ Why state management is about controlling valid actions, not just storing data ➡ Limitations of Redux and Zustand in enforcing state transitions ➡ Using Finite State Machines to make states and transitions explicit ➡ Eliminating invalid states and actions by design ➡ XState for behavior-driven UI architecture ➡ Improved predictability, debugging, and reliability in frontend systems ➡ Cleaner UI flows with fewer conditionals and hidden edge cases 📍 @itswrkwrk #FrontendEngineering #StateMachines #XState #UIArchitecture #TechSession

AI didn’t kill web developers. It exposed lazy thinking. A founder bragged to me: “AI built our website overnight.” He wasn’t lying. The site was beautiful. Fast. Polished. It just didn’t work. No leads. No conversions. No momentum. So I asked him: If your website is so good, why isn’t it selling? That’s the part no one likes to talk about. Here’s the uncomfortable truth: AI doesn’t understand your business. It imitates the internet. And the internet is full of: •Vague value propositions •Safe copy •Identical layouts •Empty buzzwords So when AI builds your site, it often builds a perfectly average one. Let me ask you this: If your competitor used the same prompt, would your website still stand out? Exactly. Because AI can’t feel customer pain. It can’t sense hesitation. It can’t argue objections. It can’t position you to win. AI gives you pages. Strategy gives you leverage. Websites don’t fail because they weren’t generated fast enough. They fail because no one decided what they should convince the visitor to believe. Final question: Is your website a brochure… or a salesperson? — I am Levi Ndu Frontend Engineer | Founder of Levlux #AI #WebDesign #Startups #Founders #ProductThinking #FrontendEngineering #BrandStrategy #DigitalProducts #Levlux
