You will review AI-generated full-stack code, system designs, and technical explanations. You will also create prompts, reference implementations, and detailed answers that show sound engineering practices.
Your evaluations will focus on whether solutions are correct, clear, secure, performant, scalable, and aligned with the prompt. You will assess both the implementation and the quality of the technical reasoning behind it.
- Review API design, authentication and authorization, data modeling, React rendering and state, Node.js runtime behavior, asynchronous work, error handling, testing, and observability.
- Fact-check technical information and write full-stack prompts and model solutions.
- Compare AI responses for reasoning quality and engineering best practices.
- Identify issues that could affect correctness, security, performance, scalability, or maintainability.
