Nice to Have * Experience with Boomi or another iPaaS platform * Prior consulting/professional-services background across multiple concurrent clients * Familiarity with legal, financial services, or another regulated industry's compliance constraints ## Description We're looking for a senior, hands-on .NET Full Stack Developer to lead three concurrent modernization initiatives: enterprise source control migration, a SharePoint-to-GCC cloud migration with AI-powered search, and legacy application refactoring. This is not a maintenance role - you will be designing the target architecture, not just executing a checklist., 2. 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: * Lead content, data, and workflow migrations from legacy SharePoint environments into Google Cloud Platform (GCP) Government / Government Commercial Cloud (GCC / Assured Workloads). * Navigate strict government security boundaries, IAM, compliance controls (FedRAMP/NIST), and GCP storage architectures. * 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). 3. Legacy Application Refactoring * Unpack, analyze, and refactor complex legacy monoliths written in older .NET Frameworks (Web Forms, WCF, MVC) and legacy VB code (VB.NET / VB6). * Re-architect legacy logic into modular, high-performance modern .NET (NET 8+) APIs with React frontends., To be direct: this role is scoped for someone who has actually done this work before, not someone who can describe it. Applications lacking verifiable specifics below will not be considered.
