    Develop a function for the adaptive learning platform that converts database field names from snake_case format (used in the backend tracking system) to camelCase format required by the frontend JavaScript components that display student performance metrics and learning progress. The function should handle any length of snake_case strings containing student performance indicators and learning module identifiers, maintaining all original characters while removing underscores and appropriately capitalizing subsequent words.
