Flow Apps — Dynamic Rule Engine
High-throughput dynamic workflow engine that parses and executes custom DSLs from JSON scripts, reducing hardcoded deployment cycles.
Problem
Business rules lived in code deployments, slowing iteration and locking product teams behind release cycles.
Approach
Built “Flow Apps” with Langium and RPC to interpret domain-specific languages, and used local LLMs plus Cursor to accelerate rule authoring.
Outcome
Rules can be authored and executed without full redeploys — a foundation for faster insurance product experimentation.
