NicaraguaWhat I'm looking for
On an ERP project, I designed and validated business workflows with BPMN and Enterprise Architect, then tested financial and inventory modules through integration and regression testing. I managed QA deliverables and defects in Azure DevOps, contributing to 98% release accuracy.
As a Software Testing & QA Supervisor, I designed and documented manual test cases for ERP and web systems. Early defect detection and root-cause analysis reduced post-release incidents by 20%, while SQL validation reduced manual verification effort by 30%; I also improved QA reporting with Power BI dashboards.
