Developed and delivered Demo Mode for the Continia E-Document Connector within the microsoft/BCApps repository, focusing on backend development and API integration using AL. The work introduced a sandbox-only environment with dedicated demo URLs for authentication and API access, allowing isolated testing and customer demonstrations without impacting production systems. By setting up a robust sandbox environment, the implementation improved testing fidelity and reduced risk, supporting faster onboarding and more reliable quality assurance for Continia E-Document workflows. All changes were traceable to specific work items, ensuring clear auditability and alignment with project planning while strengthening the overall demo and testing process.
