About

I'm Krish Nukala, a Sr. Application Engineer based in Brentwood, TN with 9+ years of experience building enterprise BI platforms and data systems in healthcare. My work sits at the crossroads of data engineering, business intelligence, and emerging AI.

At HCA Healthcare I independently led the Migration of the Mobile Heartbeat platform from Tableau to Power BI, contributed to an enterprise Teradata-to-GCP cloud migration, and supported a large-scale MicroStrategy Cloud transition. Before HCA, I engineered data pipelines for managed care organizations at CareBridge and led the Gamification platform as Technical Lead at Parallon.

I hold a Master's in Computer Science from Kent State University and have published research with the Tennessee Department of Health. I'm actively expanding into AI engineering — combining deep healthcare domain knowledge with modern AI tooling to build intelligent data systems. My I-140 is approved, making H-1B transfer straightforward for any employer.

Outside of work I maintain the Nukala Family Archive — a personal passion project preserving our family's heritage.
