Some interviews test what you know. The System Design Interview tests how you think. No tidy inputs, no green checks—just an open-ended problem and your ability to wrangle chaos into clarity. It’s the moment when whiteboards become battlegrounds and vague prompts like “design a messaging app” feel like code for “survive this mental obstacle course.” And yet, that’s exactly what makes it fun. So instead of dreading the unknown, let’s flip the script. Let’s treat this like the beginning of something great. Hello interview. Hello ambiguity, creativity, architecture, and trade-offs. Hello System Design! Let’s get to work.

Welcome to the System Design Academy, where scalability is the syllabus and architectural thinking is the core curriculum. Whether you're preparing for a big tech interview or designing production systems that serve millions,  System Design is the discipline that separates the coders from the architects. In this academy, we’ll walk through a fictional but fully practical syllabus, a tour of essential subjects, electives, labs, and graduation checkpoints for every software engineer looking to master the art of scalable thinking.

Even though System Design is often associated with senior engineers or technical architects, it is valuable to start learning it early. In this blog, you’ll learn why System Design matters for junior engineers, how to start learning it without feeling overwhelmed, and what topics will help you the most in your early career.

In this blog, you’ll get clarity on how System Design fits into the frontend space. You’ll explore what kind of system thinking is expected from frontend engineers, what topics to prioritize, and how you can build System Design intuition that actually helps you write better frontend code.

In this blog, you’ll find ways to deal with  System Design  in a hurry: A mental model for handling design interviews when time is short, stakes are high, and clarity is everything. This isn't about cutting corners. It's about cutting noise. It's about showing structure, maturity, and presence under pressure.

Welcome to System Design School, where engineering meets architecture, and you go from sketching small services to orchestrating planetary-scale systems. Whether you're just starting out or preparing for a senior System Design interview, this "school" has something for every level. In this guide, we’ll walk you through the curriculum of becoming a master architect, from orientation to graduation. So grab your backpack, class is in session!

System Design interviews are one of the most misunderstood parts of the tech hiring process. Many candidates expect a checklist of questions, only to realize midway that they’re expected to drive the conversation. So what’s the real format? Are System Design interviews open-ended or structured? In this blog, we’ll explain how these interviews are structured beneath the surface, why they appear open-ended, and how to prepare for both dimensions.

Selecting the right architectural pattern is crucial for building robust and scalable systems in today's fast-paced software environment. Service-Oriented Architecture (SOA) and Microservices are two prominent approaches, each with unique advantages. SOA emphasizes centralized governance, reusability, and interoperability, making it suitable for large enterprises. In contrast, Microservices adopt a decentralized model, allowing independent services to communicate via lightweight protocols, promoting agility and rapid deployment. Understanding the distinctions between these architectures is essential for aligning system design with business goals. This blog will compare SOA and Microservices, exploring their key features, development practices, and ideal applications to guide software development decisions.

This blog emphasizes the role of Continuous Integration (CI) and Continuous Deployment (CD) in creating resilient software systems. In today's fast-paced digital environment, CI enables developers to frequently integrate code changes into a shared repository, with automated tests ensuring stability. CD automates the deployment of these changes, allowing for quick releases and minimizing downtime. Resilient systems are characterized by traits such as redundancy, fault tolerance, self-healing, scalability, and adaptability, which help maintain essential functions during disruptions. Companies like Netflix and AWS illustrate how CI/CD practices enhance system resilience. The CI/CD pipeline consists of Continuous Integration, Continuous Deployment, and Continuous Testing, promoting early bug detection and rapid recovery from failures. Integrating CI/CD with resilient system design is essential for building robust software that effectively responds to challenges and user needs.
