What I'm looking for

I seek roles where I can build and productionize Generative AI/LLM solutions in healthcare, contribute to HIPAA-compliant MLOps, mentor teams, and drive measurable clinical and fraud-detection impact.

I am a Senior Machine Learning & Data Scientist Engineer with over 8 years of experience delivering scalable AI and ML solutions, focused on Generative AI and Large Language Models for healthcare and fraud detection.

I design and deploy end-to-end machine learning pipelines and HIPAA-compliant MLOps workflows using tools such as PySpark, SQL, AWS, Azure, Databricks, MLflow, and Airflow to accelerate deployment cycles and enable near real-time experimentation.

My work includes building RAG frameworks, LLM-driven NLP workflows, and high-volume data pipelines that improved clinical documentation efficiency by 35%, cut feature engineering time by 50%, sped claims processing by 40%, and achieved 92% diagnosis prediction accuracy.

I mentor and upskill junior engineers, champion cross-functional collaboration with clinicians and product teams, and drive productionization of enterprise-grade pilots—bringing measurable impact through robust validation, monitoring, and MLOps best practices.
