Let's talk about the hire that's quietly bleeding your budget. A Senior Full-Stack Developer. 7+ years of experience. The kind of person your product depends on. In the US, you're looking at $15,500–$19,500/month all-in. If you can even find one. Through Nir-Yu, in Latin America? $6,450/month. Total. That's it. And before you say "yeah but what's the catch"... let me show you exactly where that $6,450 goes, because that's kind of the whole point. ✅ Developer salary: you see it ✅ Benefits, taxes, compliance, EOR services: itemized ✅ Our management fee: fixed, visible, $299–$599/month No bundled mystery rate. No 80%+ markup buried in "overhead." No finding out 8 months later your developer was earning a fraction of what you thought. We call it Cost-Plus. The industry calls it unusual. I call it the only way to actually build trust with someone you're betting your product on. The savings? 67–75% compared to a US equivalent hire. But here's what I want you to sit with for a second: that's not just a cost win. It's a signal. When your developer knows exactly what they're earning and gets fair compensation, real benefits, career growth baked in, they stay. They perform. They give a damn. That's the difference between short-term savings and long-term leverage.

🔥 Stay ahead of other React Native devs by mastering Shadow Tree One of the trickiest React Native interview questions is about Fabric and how the Shadow Tree powers UI rendering. Part 1: Shadow-tree and Rendering. Quick overview but see the document for full details and diagrams: - Shadow Tree is the internal layout tree created by React Native. - It mirrors the UI tree but focuses only on layout and measurement. - Fabric uses this tree to calculate how components should look and fit. - Once the layout is ready, it sends the info to the native layer for rendering. This process keeps React Native apps smooth, consistent, and fast. ♻️ Repost to help others learn. ➕ Follow me, Mohammad for more React Native + AI resources. #ReactNative #React #JavaScript #Typescript

Hey LinkedIn fam! 👋 🚀 As a frontend engineer who's navigated countless interviews  (and helped dozens of folks land their dream roles), I've noticed these 18 questions popping up like clockwork at top tech companies (FAANG and beyond). I've grouped them by topic for easy scanning. Drop your thoughts below: Which one's tripped you up the most? 🟦 JavaScript Essentials (The backbone of it all and you're golden.) 1️⃣ Explain how closures work and give a real-world example. (Pro tip: Think event handlers in a loop!) 2️⃣ What’s the difference between var, let, and const? (Scope and hoisting—interviewers love testing this.) 3️⃣ How does the event loop work in JavaScript? (Async magic explained simply.) 4️⃣ Implement a debounce and throttle function. (For those performant search bars.) 5️⃣ Deep clone an object without using JSON methods. (Lodash who? Roll your own.) 6️⃣ Explain the concept of promises, async/await, and microtasks. (Handling the chaos of async code.) 🟩 React.js Deep Dive (Where UIs come alive—expect these in every React gig.) 1️⃣ Difference between controlled and uncontrolled components. (Form handling 101.) 2️⃣ How does React reconciliation and virtual DOM work? (The secret sauce behind fast renders.) 3️⃣ Explain useMemo and useCallback with use cases. (Optimization hooks that save battery life.) 4️⃣ How do you handle state management in large applications? (Redux, Zustand, or Context API?) 5️⃣ What are Suspense and Concurrent Rendering? (React's future-proof features.) 6️⃣ How to optimize performance in React apps? (From memoization to bundle size tweaks.) 🟨 Frontend System Design (The big-picture stuff—think architecting like a pro.) 1️⃣ How would you design a scalable dashboard (like YouTube or Uber)? (User flows, data fetching, and scaling pains.) 2️⃣ Explain lazy loading and code splitting in production apps. (Faster load times = happier users.) 3️⃣ How would you structure a large React codebase for scalability? (Monorepos, anyone?) 4️⃣ Design a notification system for real-time updates. (WebSockets and polling strategies.) 5️⃣ How do you optimize Lighthouse performance scores? (Core Web Vitals mastery.) 6️⃣ How to ensure security in frontend apps (XSS, CSRF, etc.)? (Sanitization and auth best practices.) There you have it. Your cheat sheet to frontend interview domination! If you're grinding through these, hit me up for tips or a quick mock interview. What's one question you'd add to this list? Let's chat in the comments. 🚀 #FrontendDev #JavaScript #ReactJS #SystemDesign #TechInterviews #CareerGrowth

Angular Material, Bootstrap, Tailwind, and 3 custom CSS frameworks walk into your app... Your bundle size is 15MB. Your DataGrid looks different on every page. And your junior developer just added another component library "for the date picker." UI consistency requires saying no to more libraries.

Turns out I didn’t need JavaScript for this at all Recently I found out about a neat little utility in Tailwind - line-clamp Honestly, it saved me from a bunch of unnecessary code. The task was simple: 👉 Show only 2–3 lines of text in a card or preview 👉 Add "…" at the end automatically I always used to solve it with JS. Turns out, Tailwind has it built in - just one class. Sometimes the best solution is already in your toolkit, you just need to know it exists 👇

As summer arrives and many developers take well-deserved breaks, we're curious about how Rails professionals manage to truly switch off from coding and maintain work-life balance during holiday periods. The tech industry's always-on culture can make it challenging to disconnect. With GitHub notifications, Slack messages, and that irresistible urge to check if your latest deployment is running smoothly, many developers struggle to fully unwind even during vacation time. Research shows that 84% of professionals think about work at least twice daily, even on days off. For Rails developers, this might mean mentally debugging code whilst on the beach or sketching out database schemas during family dinners. Remote work and flexible schedules, whilst beneficial, have blurred the boundaries between home and office. When your Rails development environment is always just a laptop away, the temptation to "quickly fix that bug" or "just check the server logs" becomes difficult to resist. Strategies that work: 🔹Technology boundaries: Turning off work notifications and using separate devices for personal time 🔹Creative outlets: Many developers find that activities like music, art, or cooking provide the mental reset that coding minds need 🔹Nature connection: Getting outdoors offers a complete change from screen-focused work environments 🔹Learning breaks: Some developers switch off work coding by exploring completely different programming languages or technologies for fun The summer break provides crucial time for mental reset, preventing burnout and returning to work with fresh perspectives on challenging problems. Developers who master the art of switching off often demonstrate better long-term productivity and more creative problem-solving abilities. How do you manage to truly disconnect from Rails development during summer breaks? Share your strategies for maintaining work-life balance whilst staying passionate about coding. #DeveloperWellbeing #WorkLifeBalance #SummerBreak #RubyOnRails #TechLife #TechRecruitment

If your React app feels slow, don’t start optimizing everything. Start by measuring 𝘄𝗵𝗮𝘁 𝗮𝗰𝘁𝘂𝗮𝗹𝗹𝘆 𝗰𝗮𝘂𝘀𝗲𝘀 𝘁𝗵𝗲 𝗹𝗮𝗴. Here’s my quick 3-step sanity check I use before diving into performance hell: 🧠 Wrap expensive components in React.memo() but only if props are stable. ⚡ Use the React Profiler it’s the simplest way to see wasted re-renders. 🧩 Split heavy components dynamically with React.lazy() users don’t need everything at once. The goal isn’t to make your app perfect, it’s to make it feel fast. What’s your go-to trick for speeding up React apps without overcomplicating things?

Your engineering team just told you they want to rewrite the entire frontend in React. "It'll make us move faster." Cost: $400K. Timeline: 6 months. Here's the real reason they want this: Resume building. React is hot. Angular is old. If they work in React for six months, their LinkedIn looks better for the next job. That's not malicious. It's human. But it's not aligned with your business goals. And you don't have the technical background to challenge it. So you approve it because you don't know what else to ask. Before you approve any major technology change, ask these questions: What specific business problem does this solve? Can we quantify the speed improvement? What's the opportunity cost of six months not shipping features? Have we exhausted improvements to the current stack? If the answer is "our stack is old and this one is new" - that's not a reason. That's a preference. 17 years as CTO. 28 years in technology. I've inherited "modern" codebases that were disasters. And "legacy" codebases that printed money. Technology choice matters way less than execution quality. Your team pushing for a major technology change? Schedule a call at: bry.net Let's talk through the real costs before you commit.

If you're a coder interviewing for a new job and the interviews maybe aren't going as well as you hoped or they seem to go well, but you still don't get the offer, then this is for you. Don't assume anything when you interview!! You might think that this piece of experience on your resume or this fact on your profile automatically tells the interviewer x about you. Maybe you're right, maybe you're not. Don't leave this up to chance. If you want the interviewer to know you have a growth mindset, make it obvious. Tell them you're excited to learn and grow. If you want them to know you have x experience, tell them. If you want to make your expertise in y clear, tell them. Don't assume they know anything about you or your experience. (They should know something about you if you've got to the interview, but it's best not to leave anything you consider important up to chance.) Don't assume the interviewer knows anything about you. Also, don't assume you know everything about the coding problem, question, or position. Ask questions to verify your understanding. An assumption can lead to being overlooked in favor of a candidate who clearly emphasized their experience and mindset. Don't leave your future up to chance. Don't assume in interviews. Clarify and confirm.
