• Integrate backend services with business systems, databases, Microsoft Graph and Dataverse
• Secure APIs and agent connections using Entra ID and OAuth 2.0, applying DLP policies, data protection and responsible AI practices
• Build and maintain CI/CD pipelines using Azure DevOps or GitHub Actions, and deploy agents through Power Platform ALM

• Collaborate closely with distributed project teams using Agile methodologies
• Work on projects across a range of industries and business domains
