Project Overview

At Cotiviti Technology, with over 330 production database systems totaling approximately 9 petabytes of data, we frequently encountered system failures due to unexpected storage exhaustion resulting in business disruptions and financial losses.

To solve this critical problem, I implemented an AI-powered solution using LSTM (Long Short-Term Memory) neural networks to proactively predict weekly database storage growth patterns and automatically adjust capacity requirements, transforming our reactive approach into a predictive, intelligent system.
