What I'm looking for

I want to work on LLM dataset quality—validation, rubric-based evaluation, and prompt-driven automation—so foundation-model training data stays clean and downstream performance improves.

I’ve worked on data validation and quality for foundation-model pipelines at Scale AI/Outlier, building prompt-driven anomaly detection workflows and validating 10,000+ NLP samples.

I also evaluated 1,200+ model predictions against ground truth to find performance gaps and improve model performance and data quality for downstream training.

Before that, at Turing/OpenAI, I created 1,000+ multimodal training samples, scored outputs against strict schemas, and documented 300+ error patterns to reduce dataset label noise.

I have received professional training as a Data Scientist at WIPRO.
