Freelance Oracle Database Developer - Qaiser Mehmood
Freelance Oracle Database Developer5.0 (7 reviews)

I build production AI agents for real businesses: LangGraph, MCP servers and RAG pipelines on top of .NET and Python. 21 years of .NET (1.0 to .NET 10); most recently Solutions Architect for a 1,800-person advisory firm. Stuck on an agent, a RAG pipeline, or getting Claude Code or Cursor to write better code? Let's fix it live. What I help with: • AI agents & orchestration: LangGraph, LangChain, Claude Agent SDK, OpenAI Agents SDK, Microsoft Agent Framework (Semantic Kernel + AutoGen) • Model Context Protocol (MCP): building and debugging MCP servers in C#, TypeScript and Python • RAG: pgvector, chunking, retrieval quality, evaluation • Production AI: observability, LLM cost tracking, prompt-injection defense • AI coding workflows: Claude Code, Cursor, OpenAI Codex, GitHub Copilot, Google Antigravity • Adding AI to existing .NET apps without a rewrite • Blazor Server & WebAssembly, ASP.NET Core, ASP.NET Zero / ABP • C# debugging, performance, EF Core & SQL Server • Architecture and code reviews, Azure deployment & CI/CD Open source I maintain: .NET Agent Framework, AgentWire (LLM/MCP gateway), CostWire (LLM cost dashboard), MCP Server Template, CKEditor5-Blazor. Anthropic certificates (2026): Building with Claude API · Model Context Protocol · Agent Skills · Sub-Agents. Past work includes platforms for The New York Times and Walmart. My style is hands-on: we find the root cause, fix it together, and make sure you understand the fix. If you're stuck, let's get you unstuck.
