Ritesh Khatarkar
@riteshkhatarkar
AI Trainer and Data Annotator optimizing LLMs with RLHF, prompt engineering, and culturally precise transcription.
What I'm looking for
I’m a detail-oriented AI Trainer and Data Annotator with a strong focus on linguistic data refinement and Large Language Model (LLM) optimization. I apply RLHF, prompt engineering, and hallucination reduction to generate high-quality training datasets that keep model behavior accurate and reliable.
In my work, I optimize Large Language Models through RLHF by ranking responses for accuracy, safety, and logical flow. I author high-complexity prompts and “gold standard” responses, then conduct rigorous fact-checking and editing to eliminate hallucinations and improve instruction-following.
I also train voice and language systems by producing highly accurate Hindi AI voice datasets and audio transcriptions, including real-time Hindi conversations with strangers. I strictly adhere to technical guidelines and complex project protocols to maintain data integrity and linguistic accuracy across AI platforms, while collaborating effectively in remote workflows.
