Most TypeScript engineers misuse abstract classes and interfaces because they treat them as interchangeable. Learn the structural differences, performance implications, and decision framework that separates production-ready architectures from brittle code.

Stage 3 decorators bring runtime metadata, validation, and dependency injection patterns to production TypeScript. The performance trade-offs matter more than the syntax sugar.

Production-ready TypeScript patterns that enforce API type safety from endpoint to UI. Runtime validation, discriminated unions, and type guards that catch errors before deployment.

Most TypeScript decorators fail in production because teams copy patterns without understanding the 5.0+ execution model. Here's how to build decorators that solve real problems.

Most form validation bugs trace back to runtime type mismatches. Learn how to build composable, type-safe validators that catch errors at compile time and scale across complex applications.

Learn how I prevented cascading failures in microservices using the circuit breaker pattern. Real-world examples with Node.js, configuration strategies, and monitoring approaches that actually work.
