What I'm looking for

I seek roles building production-grade LLM and MLOps solutions in regulated environments, with cross-functional collaboration and measurable impact.

I am an Applied AI Scientist with 5+ years of experience designing, deploying, and scaling Generative AI and machine learning solutions across healthcare, retail, and enterprise analytics. I specialize in LLM-based NLP systems, RAG pipelines, predictive modeling, and production-grade MLOps on cloud platforms, with a strong track record of translating business problems into scalable, compliant, and explainable AI solutions.

I have owned end-to-end model lifecycles—EDA, feature engineering, training, deployment, monitoring, and retraining—while ensuring regulatory alignment (HIPAA/PII) and measurable business impact. I collaborate closely with product, engineering, and compliance teams and have built production systems using AWS SageMaker, MLflow, CI/CD, Spark, Airflow, Snowflake, and visualization tools like Power BI and Tableau.
