• Evaluate trainer and QA submissions against project guidelines and detailed rubrics.
• Check closures, scope, hoisting, prototypes, promises, async and await, event loop behavior, modules, DOM manipulation, and error handling.
• Identify incorrect logic, code that will not run, missing edge cases, insecure recommendations, and incomplete explanations.
• Give precise written feedback on async logic, browser and Node.js differences, security, performance, and readability.
• Spot recurring quality issues and communicate workflow changes and quality expectations to trainers and QAs.
• Maintain style guides, trackers, FAQs, calibration tasks, onboarding materials, and other project documentation.
• Support onboarding and training for remote contributors and help keep contributor activity aligned with project needs.
