Frontend Developer Portfolio: React.js and TypeScript Projects

🚀 Open to Work | Frontend Developer One thing I’ve learned after 3.10 years in frontend development: 👉 Most React apps are slow… not because of React, but because of how we use it. Here are a few ways I’ve optimized React applications in real projects: ⚡ 1. Avoid unnecessary re-renders Used React.memo, useMemo, and useCallback to prevent wasteful renders. ⚡ 2. Optimize API calls Implemented React Query caching, reducing redundant API calls by 30–50%. ⚡ 3. Code splitting & lazy loading Used React.lazy and dynamic imports to improve initial load time. ⚡ 4. Efficient state management Avoided overuse of global state, used Redux Toolkit + local state wisely. ⚡ 5. List virtualization Handled large datasets efficiently using virtualization techniques. ⚡ 6. Performance monitoring Improved Core Web Vitals & Lighthouse scores through continuous optimization. These changes helped improve application performance by up to 40% 🚀 I’m a Frontend Developer (React.js | Next.js | Node.js) focused on building fast, scalable, and user-friendly applications. 📢 Currently Open to Work 📌 Notice Period: 15 Days If you’re hiring or know someone who is, I’d love to connect 🤝 📩 Email:panditdeshant@gmail.com 📱 Phone: +91-9811328120 💬 What’s your go-to React performance trick? #OpenToWork #ReactJS #FrontendDeveloper #NextJS #JavaScript #WebPerformance #SoftwareEngineer #Hiring

💡 JavaScript Tip – Difference between var, let, and const Understanding the difference between var, let, and const is very important for writing clean JavaScript code. Here’s a quick explanation: 🔹 var Function scoped Can be re-declared and updated Used in older JavaScript 🔹 let Block scoped Can be updated but not re-declared in the same scope Preferred for variables that change 🔹 const Block scoped Cannot be updated or re-declared Used for values that should remain constant Using let and const helps avoid bugs and makes the code more predictable.

💡 JavaScript Tip – Debouncing vs Throttling While working on frontend performance, I explored two important concepts: Debouncing and Throttling. These techniques help in optimizing performance when dealing with events like scrolling, typing, or resizing. 🔹 Debouncing Delays the function execution until the user stops triggering the event. 👉 Example: Search input (API call after user stops typing) 🔹 Throttling Limits the function execution to run at fixed intervals. 👉 Example: Scroll event (runs every few milliseconds) function debounce(func, delay) { let timer; return function () { clearTimeout(timer); timer = setTimeout(() => func(), delay); }; } Using these techniques helps improve performance and user experience in web applications.

💡 JavaScript Tip – What is a Closure? Closures are one of the most powerful concepts in JavaScript. A closure is created when a function remembers variables from its outer scope, even after the outer function has finished executing. function outer() { let count = 0; return function inner() { count++; console.log(count); }; } const counter = outer(); counter(); // 1 counter(); // 2 counter(); // 3 🔹 Here, the inner function still has access to the count variable, even after outer has finished executing. 👉 This is called a closure. 📌 Where it is used? Data hiding Creating private variables Callbacks & event handlers Understanding closures helps you write better and more advanced JavaScript code.

💡 JavaScript Tip – Useful Array Methods (map, filter, reduce) While working with JavaScript, I realized how powerful array methods are for writing clean and efficient code. Here are 3 important ones every developer should know: 🔹 map() Used to transform each element in an array 👉 Returns a new array 🔹 filter() Used to filter elements based on a condition 👉 Returns a new array 🔹 reduce() Used to accumulate values into a single result 👉 Returns a single value Example: const numbers = [1, 2, 3, 4, 5]; // map const doubled = numbers.map(num => num * 2); // filter const even = numbers.filter(num => num % 2 === 0); // reduce const sum = numbers.reduce((acc, num) => acc + num, 0); console.log(doubled, even, sum); Using these methods helps write clean, readable, and functional code.

Which rendering method do you use more in real projects? 🚀 ISR vs Hydration in Next.js — Understanding Modern Frontend Rendering While exploring modern frontend architecture in Next.js, I tried to understand how ISR (Incremental Static Regeneration) and Hydration work in real applications. These concepts are very important for building fast, scalable, and SEO-friendly web apps. In simple terms: ISR → Generates static pages and updates them in the background Hydration → Makes server-rendered HTML interactive in the browser Real impact in production apps: ✔ Faster page loading ✔ Better SEO ✔ Lower server load ✔ Smooth UI interaction ✔ Scalable frontend architecture Modern frontend development is not only about UI. It also requires understanding rendering strategies and performance optimization. Trying to learn more about how real-world applications are built using Next.js, React, and modern frontend patterns. 💼 Open to Opportunities Frontend Developer / Full Stack Developer / Software Engineer Immediate Joiner Tech Stack: React • Next.js • JavaScript • Node.js • MongoDB • MERN • API Integration Interested in working on real-time, scalable web applications. 💬 Discussion Which rendering method do you use more in real projects?

💻 Learning Update – React Hooks (useState & useEffect) Today I focused on improving my understanding of React Hooks, especially useState and useEffect. React Hooks make it easier to manage state and handle side effects in functional components. 🔹 useState – Helps manage component state 🔹 useEffect – Used for side effects like API calls, subscriptions, and updates import React, { useState, useEffect } from "react"; function App() { const [count, setCount] = useState(0); useEffect(() => { console.log("Component updated"); }, [count]); return ( <button onClick={() => setCount(count + 1)}> Count: {count} </button> ); } Understanding hooks helps in writing cleaner and more efficient React code.
