Design Rationale

React chosen for frontend due to its component-based architecture and large ecosystem
Node.js selected for backend to allow JavaScript across the stack and for its non-blocking I/O
PostgreSQL used for its robustness in handling complex queries and data relationships
RESTful API design chosen for its simplicity and wide adoption in the industry
Custom profiling engine built for precise control over performance analysis
AWS selected for its scalability and comprehensive suite of developer tools
Emphasis on security and data protection to build trust with users handling sensitive code
