Complex AI FinTech Platform: Agentic AI + RAG for Financial Workflows

We are building a complex AI FinTech platform for financial workflows and are looking for an expert developer to help design and build it end to end. Scope: 1) RAG pipeline over financial documents with citations: ingest and index financial documents, retrieve relevant passages, generate grounded answers with citations, and evaluate accuracy. 2) Agentic multi-step workflows with tool use and approvals: design multi-step agents that can call tools, follow financial workflows, and route sensitive or high-risk actions for human approval. 3) Secure backend APIs + dashboard: build secure backend APIs and a dashboard for reviewing workflows, documents, outputs, and audit activity. 4) AWS deployment, auth, audit logs: deploy on AWS with authentication, role-based access, secure handling of financial data, and comprehensive audit logs. Required skills: Python, LangChain/LangGraph, RAG, LLM APIs, FastAPI, React, PostgreSQL, AWS, and FinTech APIs. This is a complex, ongoing platform build. We are looking for strong communication, careful engineering, and experience shipping secure, production-grade AI systems for financial use cases.
