System Design Playbook

I’ve worked across startups, mid-sized product companies, and enterprise teams — and if there’s one truth I’ve learned, it’s this: System design isn’t just a one-time whiteboard exercise. It’s a daily practice — something you live and breathe when you’re building products that are meant to scale, survive outages, handle spikes, and actually make money. Whether I was in a fast-paced startup firefighting broken flows, or at a product company designing high-traffic APIs, one thing always stood out: Most engineers are never taught how real systems are built. You Google “system design” and find fancy diagrams, abstract terms, and interviews with no connection to how systems are actually deployed in production. That’s why I created System Design Playbook. This page is for backend developers, tech leads, and even early-career engineers who want to understand: • How do services talk to each other reliably? • When do you shard a database? • How do you scale messaging systems? • What’s a clean way to handle payments, search, or notifications? • How do you go from prompt to product with LLMs in the loop? You’ll find deep-dives into: • Booking platforms • LLM-powered chat applications • Analytics pipelines • Notification systems • Search & indexing • Real-time feeds • Queues, rate limiting, circuit breaking, caching • Service orchestration and microservice patterns Some posts are built like interview prep. Others come straight from the trenches of production design. But all of them have one thing in common: They’re buildable. They’re scalable. And they’re honest. If you care about real engineering, not résumé theater — welcome to the Playbook. Let’s sketch, scale, and ship.
