What I'm looking for

I am seeking engineering roles focused on large-scale data pipelines, ML infrastructure, and geospatial analytics at companies valuing efficiency, impact, and mathematical rigor.

I am an AI-focused Data Engineer and Mathematician with over four years of experience integrating mathematical modeling, data engineering, and artificial intelligence to build scalable, reliable systems.

I have designed and deployed large-scale geospatial and batch ETL pipelines on AWS and GCP, processed hundreds of billions of records, and enabled sub-5-second spatial queries using Apache Sedona, Spark, and ClickHouse.

I improved modularity, caching, and automation across ML training and data ingestion pipelines using Airflow, PySpark, and cloud services, delivering significant runtime and cost savings (examples include reducing exports from hours to minutes and saving thousands of dollars monthly).

Grounded in number theory with research in Vedic computation and a novel large-number multiplication algorithm, I bring mathematical rigor to practical engineering problems and a track record of awards and recognition for execution and optimization.
