  • Write and optimize SQL queries to extract, transform, and validate data
  • Review, debug, and improve existing codebases for performance, reliability, and maintainability
  • Translate ambiguous, high-level requirements into concrete, well-reasoned technical solutions
  • Apply consulting-style problem solving — evaluate tradeoffs and recommend best-fit approaches
  • Document assumptions, decisions, and implementation details clearly and precisely
  • Evaluate AI-generated code and analytical outputs for correctness and quality
