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:

- 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.
