What I'm looking for

I seek roles where I can lead ML/NLP projects, collaborate cross-functionally, build production LLM/RAG systems, and mentor teams while driving measurable product impact.

I am a data scientist with deep expertise in machine learning, NLP, LLMs, and generative AI who builds production-ready models and analytics to improve product trust, quality, and user experience. I have led data science efforts across marketplace platforms, healthcare, and market intelligence, delivering predictive models, causal analyses, and experiment-driven product improvements.

At scale, I have architected LLM-based content systems and RAG pipelines, designed analytics and policy-monitoring tools, and mentored teams while partnering closely with product, engineering, legal, and operations stakeholders. My work emphasizes rigorous evaluation, reproducible pipelines, and actionable dashboards that drive measurable business impact.
