• Implement real-time features using SignalR for live dashboard updates and cross-user notifications

• Develop and maintain a data synchronization engine that integrates legacy Oracle data sources using configurable field mappings and transform rules

• Build AI-powered features leveraging Anthropic Claude API for intelligent search, field mapping suggestions, and engineering request draft generation

• Implement role-based access control (RBAC) with JWT authentication, privilege-based page access, and multi-site scoping

• Generate PDF and Excel reports using ClosedXML for shop floor documentation and management reporting

• Collaborate with MRO operations stakeholders, shop floor supervisors, and engineering teams to translate business requirements into technical solutions

• Participate in code reviews, standards enforcement, and continuous improvement of development practices
