Lead Analytics Engineer @ Cigna Evernorth | Building Scalable Healthcare Analytics Systems

Early in my career, I thought Data Engineering was about tools. Spark. SQL. Airflow. Cloud. Now I realize: Tools are temporary. Architecture thinking is permanent. What matters more: • How data flows • Where bottlenecks occur • How systems scale • How failure is handled Pipelines solve today’s problem. Architecture prevents tomorrow’s problems. Still learning. Still building. #DataEngineering #SystemDesign #CloudArchitecture #CareerGrowth #TechLeadership #LearninginPublic
