>> About_Me

I architect highly-scalable data ecosystems and digital products. As an Associate Data Engineer, I build robust Modern Data Stack solutions utilizing Python, Databricks, and Apache Spark. My high-throughput ETL pipelines process 10M+ daily records and have slashed latency by up to 40% via deep Snowflake optimization.

Beyond traditional Big Data warehousing with Airflow and dbt, I am a passionate builder of Agentic AI workflows. I design intelligent architectures—from an Edge Store extension with 20+ features, to an AI finance PWA with active daily users. By fusing enterprise data engineering with local LLM APIs and JavaScript, I turn raw data into deeply engaging software.
