1 = Developed and enhanced Artificial Intelligence (AI) models to improve their performance and efficiency.2 = Collaborated with a team of data scientists to train AI models using large datasets comprising of over 1 million records.3 = Conducted regular testing of AI models to identify errors and inconsistencies. This involved running over 500 test caseson a weekly basis to ensure model accuracy.4 = Implemented error correction procedures to fix identified issues, resulting in a 20% improvement in model accuracy
