AI + .NET Full Stack Developer (SharePoint) -- Legacy Modernization & Cloud Migration

1. SharePoint * GCC Cloud Migration Migrate SharePoint content and permissions into a Google Cloud Platform (GCP) Government / Government Commercial Cloud (GCC / Assured Workloads)., correctly handling the security model differences, permission inheritance quirks, and compliance boundaries that don’t exist in commercial M365. You will also evaluate and implement an AI-powered search layer (e.g., Copilot/Graph-based semantic search, Azure AI Search, or equivalent) to replace native SharePoint search - this is a stated priority, not a stretch goal

• 7+ years professional full stack development experience, including 3+ years with React (or a comparable modern SPA framework) paired with a .NET backend \n

• Demonstrated, describable experience with at least one enterprise source-control migration (TFS/SVN/other * Git-based platform) where you owned the target repo/branching architecture - not just ran the migration tool \n

• Hands-on experience with Microsoft 365 GCC or GCC High, including its security/compliance differences from commercial M365 (you should be able to speak to specific differences unprompted) \n

• Working experience with at least one AI-powered enterprise search implementation (Azure AI Search, Copilot/Graph connectors, or similar) \n

• Direct experience reading, maintaining, or migrating VB.NET or classic ASP.NET/WebForms code - this is a required skill, not a preference \n

• Strong SQL Server skills (schema design, performance tuning, migration scripting) \n

• Must be prepared to complete a technical assessment: a scoped architecture and a live technical discussion where you walk through actual reasoning on a comparable migration/refactor scenario. This is how we verify hands-on depth - resume claims alone won’t move you forward. \n

• Lead content, data, and workflow migrations from legacy SharePoint environments into Google Cloud Platform (GCP) Government / Government Commercial Cloud (GCC / Assured Workloads). \n

• Navigate strict government security boundaries, IAM, compliance controls (FedRAMP/NIST), and GCP storage architectures. \n

• Implement AI Search: Replace default legacy SharePoint search with advanced AI-driven cognitive search using Google Vertex AI Search / Enterprise Search (vector search, semantic query processing, and RAG architectures). \n

1. Legacy Application Refactoring

\n \n

• Unpack, analyze, and refactor complex legacy monoliths written in older .NET Frameworks (Web Forms, WCF, MVC) and legacy VB code (VB.NET / VB6). \n

• Re-architect legacy logic into modular, high-performance modern .NET (NET 8+) APIs with React frontends. \n
