A deep technical exploration of WebSocket server internals—understand the HTTP upgrade handshake, frame protocol structure, connection lifecycle, and strategies for scaling millions of concurrent connections in real-time systems.

A practical guide to deciding whether you need a Backend for Frontend (BFF). Learn when a BFF simplifies frontend complexity, improves performance, and enables better API design—and when it adds unnecessary overhead.

A practical guide to deciding where state should live in frontend applications. Learn how to evaluate local vs global state, server vs client state, and when to use tools like React state, context, or external stores to build scalable and maintainable architectures.

A deep dive into workflow orchestration engine design—learn how to build Temporal-style durable execution systems that handle retries, state persistence, and long-running workflows reliably. Explore event sourcing, task queues, and fault-tolerant architecture for scalable distributed systems.

A deep dive into the Write-Through Cache pattern—how to keep cache and database in sync by updating both on every write. Learn the trade-offs, performance implications, and when to use this strategy for consistency-critical systems.

A practical guide to zero-downtime schema migrations—learn how to evolve production databases safely using backward-compatible changes, dual writes, feature flags, and phased rollouts. Explore strategies that prevent outages while maintaining data integrity at scale.

A deep dive into async processing in system design—learn how to decouple heavy or long-running tasks from request-response cycles using queues, workers, and event-driven patterns. Discover how to improve scalability, reliability, and user experience in modern distributed systems.

A practical guide to API versioning in system design—learn how to evolve APIs without breaking clients. Explore versioning strategies like URI, header, and schema-based approaches, along with backward compatibility, deprecation planning, and real-world trade-offs.

A deep dive into API Gateway system design—how to centralize request routing, authentication, rate limiting, and observability in modern distributed systems. Learn how API gateways simplify frontend-backend communication while improving scalability, security, and performance.

Learn how the Anti-Corruption Layer (ACL) pattern protects your system from external complexity and legacy chaos. This guide explains how to design translation layers that isolate your domain, prevent tight coupling, and enable safe integration with third-party or legacy systems.
