  • Review AI-generated code for correctness, efficiency, scalability, and reliability.
  • Create Python agents and automated checks that find error patterns and validate solutions.
  • Evaluate model performance across architecture, API design, production implementation, monitoring, and maintenance.
  • Use software engineering benchmarks to assess AI coding solutions.
