@leebabovanthomas

AI Data Engineer with 8+ years of experience building and operating enterprise scale data platforms, database systems and production AI applications.

What I'm looking for

I'm looking to build reliable enterprise AI and data platforms where I can work across source systems, unstructured data, retrieval quality, and the people relying on accurate answers.

I bring 8+ years across Coupa, ServiceNow, Epic Engineering, and Oracle, spanning ETL, warehousing, database performance, and production operations and AI systems.
I have worked and owned a range of products that spanned from ETL pipelines, distributed database architecture, AI RAG agent pipeline, data modelling and visualization. My expertise lies in the area of data engineering where you handle the non-viewable, non-usable data into an end-user viable product.
