Lead three modernization initiatives: enterprise source-control migration, SharePoint-to-GCC cloud migration with AI-powered search, and legacy application refactoring. Design and document the target GitHub architecture, including repository structure and ownership, branching strategy, environment promotion flow, required-reviewer policies, secrets management, and CI/CD pipelines; produce an architecture document and migration runbook. Migrate SharePoint content, data, permissions, and workflows into GCP Government/GCC Assured Workloads, addressing security-model differences, permission inheritance, compliance boundaries, IAM, FedRAMP/NIST controls, and GCP storage architecture. Evaluate and implement an AI-powered search solution to replace native SharePoint search, using Google Vertex AI Search/Enterprise Search or an equivalent approach, including vector search, semantic query processing, and RAG architectures. Analyze and refactor legacy monolithic applications built with older .NET Framework technologies such as Web Forms, WCF, and MVC, as well as VB.NET/VB6. Re-architect legacy application logic as modular, high-performance .NET 8+ APIs with React frontends. Technologies:
