• Implement user-facing features and the services, APIs, and data models behind them.
• Trace requests and data across browsers, applications, APIs, services, databases, and integrations.
• Understand existing architecture while working in unfamiliar codebases.
• Diagnose failures involving application state, API contracts, authentication, persistence, networking, and deployment.
• Evaluate and improve code written in multiple programming languages.
• Review AI-generated solutions for correctness, completeness, performance, security, and maintainability.
