What I'm looking for

I seek roles building production ML and scalable data platforms on cloud (AWS/GCP), with collaborative teams, strong MLOps practices, and opportunities to mentor and impact healthcare/finance outcomes.

I am a Senior ML & Data Engineer with over 11 years of experience delivering scalable data platforms and production machine learning across healthcare, finance, and manufacturing. I design and implement real-time ETL pipelines, data lakes and warehouses, and integrate ML models into production using AWS, GCP, Snowflake and Databricks.

I have led teams to deploy real-time analytics systems, ensured HIPAA and FHIR/HL7 compliance for clinical data, and mentored junior engineers on cloud infrastructure and MLOps. My focus is on operationalizing models, optimizing cloud costs and performance, and turning complex data into actionable insights for clinical and business decision-making.
