TypeScript/Node/React Claim Financial Logic & Architecture Audit

I'm seeking a senior engineer to independently audit a TypeScript/Node/React SaaS application. The focus is on financial logic, race conditions, state handling, and overall architecture. Key Areas of Audit: - Financial eligibility and deterministic claim calculations: - Reconciliation - Export logic - Cross-screen financial consistency - Financial eligibility propagation - Readiness-dollar calculations The ideal candidate should have: - Extensive experience with TypeScript, Node.js, and React - Strong experience auditing deterministic financial calculations, eligibility rules, and data-flow logic -The auditor must independently inspect the actual repository and provide evidence from the current codebase, not rely solely on prior AI-generated summaries or test conclusions - Expertise in identifying race conditions and state management issues - Strong software architecture experience; first phase is audit and evidence, not implementation Please include relevant experience in your bids.
