Optimized and redesigned ETL processes reducing execution time from 4+ hours to 1 hour (Improved processing speed by 300%) for 25+ processes, implementing fault-tolerance and self-recovery mechanisms.

This benefited the Engineering department in different ways:

• Data was up-to-date and on the timeframe they needed.
• Reliability; they have the confidence that data is always correct and if errors occurred, they are non-critical and can be quickly fixed.
• Scalability, ETL processes can be scale more easily because the scripts were modified in a way that adding or deleting fields is easier for a developer.
