Direct and oversee a pod of offshore back-end engineers by assigning work, conducting code reviews, and ensuring production-ready output.
Design and own the Azure SQL transactional cache schema.
Design and implement REST API endpoints exposed through Azure API Management (APIM), consumed by the React frontend.
Implement write-path logic that routes commit actions (budget approvals, PO releases, change orders) through Azure Service Bus to OIC flows and back to the ERP.
Enforce business logic, data validation, and error handling standards within the service layer.
Own CI/CD pipeline compliance for backend code, ensuring all commits pass Veracode SAST + SCA security scanning before merging.
Lead bi-weekly sprint demos for backend workstreams, ensuring all service layer work is demo-ready on schedule.
Resolve and triage backend defects during SIT, UAT, and post-launch hypercare within agreed SLA windows.
