🚀 Just launched Mojito Motion — a smooth animation playground built with React + GSAP! Scroll-triggered animations, timeline magic, and a clean responsive UI 🍹✨ 🔗 Live: mojito-motion.vercel.app 💻 Code: github.com/VirendraT11/Mo… #ReactJS #GSAP #Frontend @VirendraCodes

⚡ POTD crushed in just 5 minutes! Simple logic, clean approach, and smooth execution 🚀 Sometimes the easiest solutions hit the hardest 💡 Consistency > Complexity 🔥 #LeetCode #Coding #ProblemSolving #100DaysOfCode

Why this matters for YOU: If you can: • Build pipelines • Model clean data • Write efficient queries You’re already ahead of most devs in data engineering 🚀 Bookmark this & start learning one tool deeply. #DataEngineering #BigQuery #Snowflake

Counterintuitive truth: You don’t optimize warehouses for storage. You optimize for queries. Column storage + partitioning = faster analytics Bad query = high cost 💸 Good query = 10x efficiency Have you ever hit a huge query bill?

Most devs think BigQuery, Snowflake, Redshift are just “big databases”. They’re not. They’re the decision engines behind billion-dollar products. If you’re ignoring Data Warehouses, you’re missing one of the highest-impact skills in tech. 🧵

Cracked today’s LeetCode POTD 💻🔥 ⏱️ Solved in 20 mins ⚙️ Medium complexity & code size 🧠 Clean logic + efficient approach Consistency paying off 📈 #LeetCode #Coding #DataStructures #ProblemSolving

WebRTC is underrated for data engineers too. Push sensor telemetry directly to a dashboard browser. No Kafka consumer overhead. No REST polling. Just raw, encrypted P2P streams. 🔥 Are you sleeping on WebRTC? #WebRTC #WebDev #BuildInPublic

2 beginner projects to actually learn it: 📁 P2P File Transfer — send files browser-to-browser, zero server upload 🎥 Video Chat App — 2 tabs, 1 weekend, real RTCPeerConnection code Both teach you the full handshake: offer → answer → ICE → stream.

Most devs don't know this — your browser can stream video, audio & data directly to another browser. No server relay. No plugin. Just native browser magic. It's called WebRTC 🧵

Started the day strong 💪 Solved a LeetCode SQL problem: Department Top 3 Salaries 📊 Clean use of DENSE_RANK() and window functions — great way to sharpen SQL thinking! #LeetCode #SQL #DataEngineering #100DaysOfCode

Cracked today’s LeetCode POTD 💻🔥 Solved it in ~30 mins ⏱️ Felt a bit logic-heavy 🧠 but manageable. Code was medium in size & complexity — good balance of thinking + implementation. Another step forward 🚀 #LeetCode #DSA #ProblemSolving

Beginner project ideas 💡 1. Build a 1:1 video call app using WebRTC + a free STUN server (no backend needed to start) 2. Add a Redis-backed room system + track join/leave events What part of this system would YOU want to build first? #SystemDesign #WebRTC #BackendEngineering

How it scales globally: → GeoDNS routes you to nearest media server → Mumbai & NYC users hit different SFU nodes → Those nodes bridge over a low-latency backbone → Session state lives in Redis, events flow through Kafka Your "simple video call" spans 3 continents.

Most devs think video calls are just "streaming video" 😅 Zoom, Meet, Teams — they're distributed systems solving latency, scale & network chaos simultaneously. Here's how a Multi-Conference Video Call actually works under the hood 🧵

If you're building projects, start simple: Create 2 services (Node.js + Express) Connect via REST Then add Kafka/RabbitMQ 💡 Question: Have you tried event-driven systems yet? Follow @VirendraCodes for real backend insights 🚀 #SystemDesign #Backend #Microservices

Here’s the interesting part 👇 Most beginners overuse APIs (sync) ❌ But at scale, async systems win: Better performance Fault tolerance Loose coupling Example: Order placed → Kafka event → multiple services react

Most developers learn APIs… but struggle with how services talk to each other at scale 🤯 That’s where Inter-Service Communication comes in. It’s the backbone of microservices and system design. Let’s break it down simply 🧵👇
