What I'm looking for

I’m looking to build cloud-native data lakehouses and real-time pipelines end-to-end, with strong DataOps, governance, and cost optimization—leading teams and translating complex business needs into resilient, scalable platforms.

I’m a results-driven Senior Data Engineer and Cloud Architect with 10+ years of experience designing, building, and scaling enterprise data platforms across healthcare, fintech, manufacturing, and technology. I translate complex business requirements into resilient, cost-optimized cloud-native architectures.

At UHY LLP, I architected and delivered a cloud-native data lakehouse on AWS and Snowflake, consolidating 30+ sources for 500+ users across 6 business units. I led migrations from legacy ETL to dbt Core and AWS Glue, cutting latency from 24 hours to under 90 minutes and reducing infrastructure costs by 42%, while driving 99.8% pipeline reliability.

I’ve also built privacy- and compliance-forward platforms. At iRhythm Technologies, I engineered a HIPAA-compliant AWS platform processing 2TB+ of daily telemetry data, and created Kafka + Spark streaming pipelines that reduced clinical alert latency to under 5 minutes with zero data loss—supported by Delta Lake, time-travel, and end-to-end traceability.

Across my career, I’ve strengthened DataOps/MLOps, governance, and automation—moving clients to Snowflake, implementing IaC with Terraform, and setting up CI/CD practices with automated data quality checks. I enjoy leading teams, mentoring engineers, and enabling self-service analytics with strong data trust and security.
