What I'm looking for

I’m looking to lead data platform teams building compliant lakehouse and streaming systems—governed with Unity Catalog and RBAC, observable end-to-end, and aligned to business outcomes, with room to integrate emerging MLOps/LLMOps and RAG pipelines.

I’m a Lead Data Engineer with nine years of experience designing and delivering enterprise-scale data platforms across healthcare, financial services, and technology. I architected a multi-tenant lakehouse platform using Databricks, Snowflake, and ClickHouse, standardizing Medallion (Bronze–Silver–Gold) ingestion and transformation frameworks to improve reliability across engineering teams.

I build secure, compliant pipelines end-to-end—FHIR/HL7 ingestion with schema validation, Unity Catalog governance with fine-grained RBAC, lineage tracking, audit logging, and PHI masking—while implementing real-time architectures with Apache Kafka and Spark Structured Streaming processing millions of events per hour. I’ve also led teams from 4 to 11 engineers, reduced annual cloud platform spend by 35%, and built multi-cloud data architectures spanning Snowflake, Redshift, BigQuery, and ClickHouse with Spark, dbt, and strong observability.
