Cover image for Build or Modernize a .NET REST API
A focused one-week API sprint for a clearly scoped module, integration, or modernization need.
WHAT I CAN DELIVER • ASP.NET Core REST endpoints and integrations. • SQL Server or PostgreSQL data access. • Validation, ProblemDetails, authentication-aware design, and clear error handling. • Automated tests, OpenAPI documentation, health checks, and Docker when useful. • Git and CI/CD-ready source, plus Azure or AWS deployment handoff when in scope. • RAG integration when in scope, using Microsoft Semantic Kernel, LLMs, embeddings, vector databases, and document ingestion, chunking, indexing, and update pipelines for knowledge-base chatbots or semantic search.
You receive working code, setup documentation, an API contract, and concise handoff notes. Larger systems are scoped separately before work begins.
