Automated reporting modules to email diff results to stakeholders. Used regularly for use cases such as quant data validation between stg vs prod. The framework was also used for major projects such as Pandas 0.16 to 0.23 upgrade, SQL 2012 to SQL 2017 upgrade as well as Data Center Migration.
  • Define and automate acceptance tests.
  • Collected real, reusable test parameters by monkey patching specific containers to publish the real-time params to Kafka. Testcases were created automatically by our in-house testing framework by consuming the Kafka stream.
