My paper: https://arxiv.org/abs/2509.19325 https://github.com/jouya97 Synthetic data, evals, and LLM wrappers. Prompting *********** Acknowledged on: -"Training language models to follow instructions with human feedback": https://doi.org/10.48550/arXiv.2203.02155 -"Learning to summarize from human feedback": https://doi.org/10.48550/arXiv.2009.01325 While I would love to go in-depth about my experience with LLMs, the truth is almost all the details of my roles are NDA-bound. That may seem like I've worked on super exciting, top-secret AI projects, but in reality I spend most of my time looking at Cursor or ChatGPT with my face contorted in confusion. *I can't and won't help you get a job at OpenAI. Please stop asking.*
