As a Senior AI Trainer & Software Engineer at TELUS Digital, I provided RLHF strategy for large language model development. My role involved evaluating, rewriting, and ranking AI-generated computer code, especially in Python and TypeScript, to improve model performance. I designed adversarial prompts and offered rationales for high-quality model outputs. • Conducted exhaustive technical code evaluations for logic, security, and efficiency. • Authored gold standard code rewrites for model training in modularity and readability. • Ranked and rated LLM outputs, selecting optimal samples for training steps. • Developed edge-case prompts and documentation to expand LLM logical capacity.
