Axiom Ledger
Event-Sourced AI Workflow Engineer
Event-sourced lending pipeline for document intake, extraction, credit analysis, fraud, compliance, and decision orchestration over an append-only ledger.
"Modeled lending decisions as replayable event streams so every agent action has an audit trail."
Problem
AI-assisted lending workflows need strict traceability across document processing, credit reasoning, fraud checks, compliance blocks, and final decision outcomes.
Solution
Created a canonical event schema, synthetic company/document generator, in-memory and PostgreSQL event stores, multi-agent pipeline phases, optimistic concurrency tests, projections, and refinery-backed document extraction.
Deep Dive
What It Tracks
Axiom Ledger represents lending workflows as streams of immutable events. Document packages, extraction results, credit analysis, fraud checks, compliance decisions, and orchestrator outcomes can all be replayed from the ledger.
Engineering Highlights
- •45 event types: typed envelopes and schemas define the domain contract.
- •Five-agent pipeline: document, credit, fraud, compliance, and decision orchestration phases.
- •Document Refinery integration: financial facts can be extracted from PDFs and normalized into ledger events.
