What I'm looking for

I seek a senior data engineering role building secure, scalable cloud data platforms, prioritizing data quality, ML readiness, and cross-functional collaboration in a results-driven team.

I am a results-driven Senior Data Engineer with 10+ years designing scalable, cloud-native data solutions across healthcare, fintech, energy, and retail. I build real-time and batch pipelines, lakehouse systems, and machine-learning-ready data at scale using Databricks, Snowflake, Apache Spark, Airflow, dbt, and AWS/Azure.

At SmarterDx I designed an AWS-native clinical data pipeline across 200+ hospitals, reducing processing latency by 40% and contributing to a 5:1 ROI; I built a centralized ML feature store and automated infrastructure provisioning with Terraform and AWS CDK. Previously, at C2FO I refactored batch ETL into real-time flows with Kafka and Spark on Databricks, enabling over $4B in funding activity and cutting data latency by 60%.

I bring a strong focus on data quality, governance, and secure architectures (HIPAA-compliant implementations), and I partner with product and analytics teams to define data contracts and accelerate deployment velocity. I am passionate about clean architecture, high-performance pipelines, and enabling analytics teams with trusted data.
