Full Stack Node.js/PostgreSQL Engineer with AI for Financial Institutions

Company Description RealDayEye is an AI-focused company that helps businesses improve efficiency, decision-making, and customer experience by embedding artificial intelligence into everyday operations in a practical and measurable way. The company builds intelligent, cloud-based platforms that automate complex, document-intensive workflows, with a strong focus on regulatory compliance and income verification in highly regulated sectors such as U.S. real estate. Its platform combines document AI (OCR, parsing, structured data extraction) with a configurable rules engine to process, validate, and audit large volumes of documentation while reducing manual work and human error.

Delivered as a multi-tenant SaaS solution, the system supports end-to-end workflows, including document ingestion, AI-driven data extraction, rule evaluation, human-in-the-loop validation, and audit-ready analytics. Early prototypes have been validated by major institutional real estate firms, demonstrating strong market demand for RealDayEye’s automation and compliance solutions.
