Freelancer Overview

I have contributed to the development of large language models at Invisible Technologies, including prompt creation, response assessment and rating, retrieval-augmented generation (RAG), reinforcement learning from human feedback (RLHF), supervised fine-tuning (SFT), and crafting ideal responses. I have also worked on voice training projects for RWS, involving Turing tests, human-likeness evaluation, audio quality assessment, and voice archetype analysis. At Telus International, I moderate harmful and misleading video and image content, provide recommendations for improving data training processes, and support team management activities.
