What I'm looking for

I seek senior roles building reliable, real-time data platforms and production RAG/LLM systems at companies valuing measurable impact, cost-efficiency, and team mentorship.

I am a Senior Data Engineer and Analytics Engineer with 10+ years building production-grade data platforms across energy-tech, fleet-tech, and AI-native environments. I design real-time CDC streaming systems, lakehouse architectures, and dbt-driven ELT pipelines while driving measurable business impact.

My hands-on expertise spans AWS, GCP, and Azure, Databricks, Snowflake, BigQuery, Apache Kafka, Flink, Spark/PySpark, and production RAG/LLM stacks including vector databases and LangChain ecosystems. I have delivered multi-hundred-thousand-dollar cloud savings, dramatically reduced pipeline incidents, and achieved sub-200 ms latencies at scale.

I lead and mentor engineering teams, implement data contracts and observability, and operationalize ML and LLM workflows. I prioritize reliable, cost-efficient architectures that enable self-service analytics and accelerate AI product launches.
