#System Design

Design the architecture of an e-commerce platform.

Design an end-to-end system encompassing: - Candidate-led requirement gathering (functional and non-functional requirements). - Definition of entities, DB schema, relationships, constraints, and cardinality with justifications. - Detailed API design including request and response schemas for all core endpoints. - High-level architecture and inter-service communication. - In-depth discussion of microservice patterns including Circuit Breaker, Saga, CQRS, and Event-Driven architecture.

Design an extensible logging system including Logger, sink interfaces, and Strategy/Factory ideas, while incorporating SOLID principles. Discuss interactions, edge cases, and trade-offs.

Describe a scenario where you were actively involved in end-to-end technical solutioning for a complex feature or system requirement.

Explain your past projects, specifically diving deep into the Order Book Engine project, including its core features, internal architecture, and data flow.
