I build AI agents that do real work inside business systems: MCP servers, LLM tool calling, RAG, and voice/chat agents, on top of 18+ years of C#/.NET, Azure and DevExpress XAF engineering. Top Rated, 100% Job Success. What I've built recently: • MCP servers: published the data pipelines of an enterprise integration platform as MCP tools, including a Streamable HTTP (SSE) endpoint that Copilot Studio, GitHub Copilot, Claude and Cursor connect to directly, with token scopes, per-topic tool authorization and tool-call cancellation. • LLM chat with tool calling: an in-product AI chat (Blazor + Azure Functions) that runs tools against live data, with async processing over Azure Service Bus, selectable models, saved prompts and cancellation. • RAG: a retrieval-grounded assistant prototype that drafts integration scripts from API specs, using OpenAPI chunking, Qdrant vector search and embeddings, with output validated by a real parser and an LLM repair loop. • Voice and chat agents: on a multi-channel conversational AI platform (phone, WhatsApp, web chat) built on LiveKit, OpenAI Realtime, Deepgram and Google TTS, I worked on the WhatsApp agent, the inbound phone agent, agent tools (calendar booking, WooCommerce, document search) and a WordPress chat plugin. What I can do for you: • AI agents & MCP: connect your database, API or SaaS product to Claude, ChatGPT or Copilot through an MCP server or a tool-calling agent. • RAG & knowledge assistants: chatbots that answer from your documents and data. • Voice AI: inbound and outbound phone agents, plus WhatsApp and web chat agents with calendar, CRM and e-commerce tools. • AI inside .NET apps: add LLM features to existing C#/.NET, Blazor, Azure or DevExpress XAF systems without a rewrite. • DevExpress XAF & Blazor: new builds, customization, WinForms / Web Forms to Blazor migration, and long-term maintenance. • Integrations & data pipelines: Azure Functions, Service Bus, REST APIs, SQL Server, CDC / ETL, Stripe billing. • Mobile: Flutter and React Native apps with Firebase or .NET backends. How I work: I start with a short call or a written plan, ship in small milestones you can test, and stay available after delivery. Several of my Upwork clients have come back for repeat contracts.
