Modern software must handle massive traffic spikes, frequent feature releases, and global user bases without sacrificing reliability or cost efficiency. Senior engineers accomplish this by combining High-Level Design (HLD)—the big-picture system blueprint—with Low-Level Design (LLD)—the code-level details that make the blueprint executable. Mastery of both layers turns conceptual ideas into resilient, maintainable products.
- SOLID Principles – Single Responsibility, Open/Closed, Liskov, Interface Segregation, Dependency Inversion.
- Design Patterns – Factory/Builder for object creation, Strategy/Observer for behavior, Adapter/Decorator for flexibility.
- Object Modeling – Entities, value objects, aggregates, and domain services that reflect real-world concepts.
- Schema Design – Choosing SQL vs. NoSQL, indexing, sharding keys, and migration strategy.
- API Design – REST/GraphQL conventions, versioning, pagination, idempotency, error contracts.
