CanadaWhat I'm looking for
At Western Union, I managed reliability for QA/UAT financial transactions and maintained 99.5%+ availability on transaction paths. I standardized critical-incident triage and built a transaction-flow runbook that helped teams isolate failing transactions faster.
As Senior Cloud Engineer at Western Union, I created reusable AWS CloudFormation templates that reduced environment provisioning from days to 45–90 minutes. Earlier, I worked on CI/CD at Western Union and network reliability at Calix, HARM, Wipro Technologies, and Broadcom Corporation.
