“Why Is My API Crying?” — Meet Messaging Queues, the Unsung Heroes of Scalability by Sahil Khan on May 6, 2026 12 views
🚨 A Familiar Problem: The “Just One More Call” Spiral You’ve built a user registration API. It works great. Until your product manager says: “When a user signs up, we should send them an email. Oh, and an SMS. Oh, and a push notification.” You nod, smile, and write this: public void notifyUser(User user) { sendEmail(user); sendSMS(user); sendPush(user); } It works… at first. Then one day, the email service is slow, the SMS times out,…
Demystifying Apache Kafka: The Internal Architecture Driving Massive Event Streaming by Nitin Goyal on April 20, 2026 261 views
Imagine you’ve just built a thriving healthcare platform. Everything is humming along nicely until one fateful afternoon. A doctor requests a critical OTP to log into the portal. Exactly 0.5 seconds prior, your marketing team triumphantly clicked “Send” on a promotional SMS broadcast to 500,000 users. In your monolithic server, a thread loops over the 500,000 users in the database. Think about the sheer weight of that transaction for a moment: fetching thousands of users…

From Developer to Architect -Episode1 by Shifa Salheen on March 10, 2026 211 views
Everything Worked, Until Traffic Arrived Ever heard terms like Horizontal scaling and Vertical scaling? They appear everywhere in architecture diagrams, in interviews, in system design conversations. At first, they sound like infrastructure jargon. Abstract. Distant. Something you’ll “learn later.” But they aren’t. They’re part of a transition every developer eventually goes through often without realizing it. From Writing Code to Designing Systems You start as a developer. You write code. You focus on features. You…

You’re sitting in a cafe, chilling ☕ — where the drinks are overpriced and the atmosphere is a mix of music, chatter and one guy whose laugh sounds like an engine starting. 🚗 Suddenly, a song starts playing and you know you’ve heard it before.

Dear Code, you had One Job! by Hardik Kardam on October 31, 2025 581 views
Hey everyone! Ever been super proud of a chunk of code you wrote, only to have it blow up in your face later? 🤦♂️ That's exactly what happened to me recently. I was building a task manager for a surgery module. It was a pretty complex system with all sorts of entities: surgery_master, TaskMapping, surgery_booking, task_master, and a full-blown Task entity. My code was split into a couple of services and data classes, and I…

Every morning, our mom becomes a silent multitasking magician. She’s making tea, loading the washing machine, chopping vegetables, and waking everyone up almost at the same time. You watch in awe, wondering how it’s even possible. With just two hands, she keeps the entire household moving like a well-coordinated system. Here’s the secret: she’s not actually doing everything at once, but rather switching smartly between tasks. While the tea boils, she folds clothes. When the…
