AI Trainer – Coding

As an AI Trainer at Alignerr, I evaluated the production-readiness of AI-generated code from an LLM CLI tool. I used prompt engineering and comparative model evaluation to review outputs for readability, modularity, and logical correctness. I ensured outputs adhered to industry coding standards for Python, TypeScript, and JavaScript. • Assessed AI code for logic and modularity. • Used prompts to elicit better model outputs. • Reviewed and rated code quality across multiple criteria. • Helped ensure user-ready coding solutions.
