gRPC vs REST: Real Benchmark Results in Spring Boot Microservices by Sahil Khan on September 17, 2026 56 views
Introduction As microservice architectures mature, the cost of service-to-service communication becomes increasingly visible. What initially appears as minor serialization or transport overhead starts compounding across service hops, often surfacing as increased latency, higher CPU utilization, and rising infrastructure costs. REST has been the default communication standard for distributed systems for more than a decade due to its universality and ecosystem maturity. However, when internal service communication begins to dominate request processing time, teams often evaluate…
Hooked on Hooks: Building Cleaner, Reusable React Logic by Sahil Khan on September 11, 2026 120 views
If you’ve been coding in React for a while, you’ve probably typed out useState or useEffect more times than you care to admit. It’s second nature at this point. But after a while, you might notice yourself copy-pasting the same little chunks of logic from one component to another. That’s where custom hooks come in. When React introduced hooks back in version 16.8, it felt like a secret weapon. Suddenly, we didn’t need class components…
Inside Envelope Encryption: The Pattern Behind Secure Systems by Kanchan Sikder on August 25, 2026 224 views
The Problem Encryption Alone Can't Solve When we think about encryption, our attention naturally goes to the data. Medical records.Financial transactions.Identity documents.Personal photos. These are the assets we want to protect. Yet modern security systems don't spend most of their effort protecting the data itself. They spend it protecting something much smaller i.e. the encryption keys. At first, this might sound surprising. An encrypted document without its key is nothing more than a sequence of…

DPDPA Episode 1: The Privacy Reality Check: Why India’s DPDPA is Everyone’s Business (Not Just Banks and Hospitals) by Hiren Morzariya on July 6, 2026 376 views
For the better part of 15 years, my job as a software engineer has been to make data flow faster, store it cheaper, and analyse it deeper. Currently, at Tech Company, we tackle massive, complex architectures daily. When we design systems like Public Health Platform—a heavy-duty digital health platform—privacy isn’t just a feature; it is the entire foundation. When you handle patient records, you naturally build zero-trust networks and obsess over access controls. But a…
Enterprise Query Design with Built-In Authorization Guarantees by Hardik Raja on June 16, 2026 422 views
Introduction: Why Authorization Matters Imagine you’ve discovered an internal bank API. This API, when called, returns the last N transactions of the logged-in customer. If you’re logged in as User A, it should only return User A’s transactions.Even if you know User B’s account number, calling the API with your own session must not return their data. This is possible because authorization checks are enforced on top of the query. Now, suppose the bank launches…
When Code Talks Business: Thinking Beyond Code by Istiyak Shabbir Vasiwala on June 4, 2026 476 views
When Code Talks Business: Thinking Beyond Code Ever feel like you're speaking a different language from the rest of the company? You know, you talk about APIs, microservices, and CI/CD, and they just nod and smile. Meanwhile, your product managers are talking about KPIs, ROI, and customer retention, and you just nod and smile. As software developers, it’s easy to get caught up in the code. We love clean architecture, elegant solutions, and bugs that…
“Why Is My API Crying?” — Meet Messaging Queues, the Unsung Heroes of Scalability by Sahil Khan on May 6, 2026 902 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 1,170 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…
Dear Code, you had One Job! by Hardik Kardam on October 31, 2025 1,219 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…
