Managing personal expenses manually is messy. So I built a full-stack Expense Tracker using the MERN stack. The application allows users to securely track their financial activities and visualize their spending patterns through an interactive dashboard. Key Implementation Highlights: • Authentication system using JWT • Protected backend routes for secure data access • RESTful APIs built with Node.js and Express • MongoDB database with Mongoose models • Advanced transaction filtering (type, category, date range) • Analytics dashboard with spending visualizations Live Application: https://lnkd.in/e6diwgiC GitHub Repositories: Frontend: https://lnkd.in/eZqMi_eY Backend: https://lnkd.in/exfR6zGH Tech Stack: React | Node.js | Express | MongoDB | JWT | Chart.js #FullStack #MERNStack #SoftwareDevelopment #React #NodeJS

I built an Expense Tracker to understand where money actually goes. Most people track income. But very few truly analyze their spending patterns. So I built a modern Expense Tracker Dashboard that helps users clearly see where their money is going through visual insights and simple analytics. What it can do: • Track and manage expenses easily • Filter expenses by date range • Visualize monthly spending trends • See category-based spending distribution • View total expenses and expense counts instantly • Clean dashboard with simple financial insights Instead of looking at rows of numbers, the app shows: • Monthly trend charts • Category distribution pie charts • Category breakdown with percentages This makes it easier to quickly answer questions like: 👉 Where am I spending the most money? 👉 Which month had the highest expenses? 👉 Which categories are draining my budget? 🛠 Tech Stack Frontend: React Backend: Node.js Database: PostgreSQL Building projects like this helps me continue improving my skills in full-stack development, data visualization, and building practical tools that solve real problems. Next step: Adding budgets, alerts, and financial insights powered by analytics. Always building. Always learning. #React #NodeJS #PostgreSQL #FullStackDevelopment #WebDevelopment #SoftwareEngineering #BuildInPublic #DeveloperJourney

The 3-second delay that was quietly killing user retention (and how we fixed it). Have you ever watched a beautifully designed app UI freeze while waiting for the backend to catch up? Recently, we ran into a bottleneck where a core dashboard was taking over 3 seconds to load. In the mobile world, 3 seconds might as well be a lifetime. Users were bouncing, and the experience felt sluggish. Instead of just throwing more server resources at the problem, I decided to tear down the request lifecycle and find the root cause. Here is how we turned a 3.2-second load time into a lightning-fast 200ms response: The Diagnosis: The issue wasn't the frontend UI. The Flutter app was rendering perfectly, but it was starving for data. Diving into the Laravel backend, the culprit became clear: the classic N+1 query problem, compounded by a lack of proper indexing on a rapidly growing PostgreSQL database. The Execution: Database Overhaul: I audited our PostgreSQL tables and implemented targeted composite indexes for the specific columns our heavy queries were filtering against. Backend Refactoring: I rewrote the underlying Laravel Eloquent relationships, replacing lazy loading with strict eager loading and raw SQL joins where the ORM was generating inefficient queries. Frontend Optimization: On the Flutter side, I implemented a more robust caching strategy and skeleton loaders so the user instantly felt progress the millisecond they opened the screen. The Result: API response times plummeted by over 90%. The dashboard now loads seamlessly, creating a significantly smoother user journey. Reduced database CPU load, saving us future scaling costs. As a full-stack developer, moments like this are why I love what I do. It’s not just about building features; it’s about writing code that respects the user's time and scales elegantly under the hood. #FullStackDevelopment #SoftwareEngineering #Laravel #Flutter #PostgreSQL #TechCaseStudy #WebDevelopment #Coding

🚀 How I Build Projects: Frontend First, Always. When I started building my latest project, I had a choice — where do I begin? Backend? Database? Architecture docs? Nope. I opened my code editor and started with the UI. Here's my stack & strategy 👇 🛠️ Stack: Next.js + MongoDB 🎯 My Approach — Frontend First: I always start with the frontend, and here's the honest reason why... When I build the UI first, I can see what I'm creating. There's something incredibly motivating about watching a page come to life on your screen. It keeps the energy alive. It keeps me going. Starting with a blank backend? That's invisible work. No dopamine hit. No "wow, this is actually happening" moment. But when you see your design render in the browser for the first time — that's fuel. 📐 My Design Principles: → Build what you can see first → Let the UI decisions guide your data models → Understand your product before you architect the backend → Ship something that feels real, fast ⚙️ Then comes the backend: Once the frontend is shaped, I know exactly what API routes I need, what data structures make sense, and how MongoDB should be modeled. The backend becomes a reaction to a clear vision — not a guess. Frontend-first isn't just a workflow. It's a mindset. Build the dream first. Make it real after. What's your approach — frontend first or backend first? Let me know in the comments 👇 #WebDevelopment #NextJS #MongoDB #BuildInPublic #Developer #IndieHacker #Programming

💡 A Small MERN Stack Tip That Improves Performance & Code Quality After working with the MERN stack for a few years, one thing I’ve noticed in many projects is how easily API performance and frontend rendering can get out of control if a few patterns aren’t handled properly. One habit that has helped me a lot is moving data shaping to the backend instead of the frontend. In many apps, the frontend fetches a large payload and then filters, maps, and restructures it inside React components. This often leads to unnecessary re-renders, heavier components, and more complex state management. A better approach is to shape the response directly in the backend (Node + MongoDB). For example: • Use MongoDB aggregation pipelines to filter and format data • Only send the fields the UI actually needs • Handle pagination, sorting, and transformations at the API layer This keeps the React side much cleaner: ✔ Smaller payloads ✔ Faster rendering ✔ Simpler components ✔ Easier state management Your React components should ideally focus on presentation and interaction, not heavy data processing. Small architectural decisions like this make a huge difference as applications scale. Curious how other developers handle this — Do you prefer data transformation in the backend or the frontend? #MERNStack #ReactJS #NodeJS #MongoDB #FullStackDevelopment #WebDevelopment

🚀 Stop using useEffect for Data Fetching Still fetching data inside a useEffect? It’s time for an upgrade. While useEffect works for simple cases, it quickly becomes a nightmare as your app grows. The Old Way (The Struggle) 😫 Using useEffect means you have to manually manage: Loading & Error states for every single component. Caching (so you don't fetch the same data twice). Race conditions and cleanup logic. Stale data that stays on the screen too long. The Smart Way: React Query (TanStack) ⚡ Switching to React Query handles the heavy lifting for you. Your code stays clean, and your app feels faster. Automatic Caching: It remembers your data so you don't have to fetch it again. Smart Refetching: It updates data in the background when the user refocuses the window. Built-in States: No more const [isLoading, setIsLoading] = useState(true). It’s already there. Next.js Ready: Works perfectly with Next.js for seamless server-side or client-side fetching. Pro Tip: Pair React Query with a Node.js backend and MongoDB. Your backend handles the data, and React Query ensures your frontend stays perfectly synced without the "spaghetti code." Are you still team useEffect, or have you made the switch? 👇 Follow Mizaan Shaikh for more #Codewithmizaan #ReactJS #NextJS #ReactQuery #NodeJS #MongoDB #Frontend #WebDev #CleanCode
