• Experience with containerization and/or cloud-native tooling (Docker, Kubernetes)
• Working knowledge of SQL databases and general data modeling concepts
• Ability to troubleshoot issues across the stack (e.g., debugging data flow, resolving data retrieval issues)
• Understanding of end-to-end web application data flow (UI → backend services → database)
