Build a DSL for Insurance-Policy Rules in OCaml

FreeVerified credential3 weeksIntermediate

Overview

What this challenge is about.

Design a small DSL covering: variables (insured amount, premium, deductible, named perils), expressions (arithmetic, conditionals, lookups against external tables like CRESTA zones), policy outputs (covered/not-covered, payout-amount, sublimits). Implement parser + interpreter in OCaml. Use OCaml's ADT support for the AST and pattern matching for evaluation. Port 6 representative rules from the Java codebase. Run a usability test with 3 actuaries (anonymized session notes). Deliver the OCaml DSL implementation, 6 ported rules, and an 8-page writeup including actuarial-readability evidence.

The Brief

What you'll do, and what you'll demonstrate.

Design and implement a small OCaml DSL for insurance policy rules that actuaries can read and author themselves, with 6 real rules ported as proof.

Earning criteria — what you'll demonstrate

  • Design a small DSL with non-engineer end users in mind
  • Implement parser combinators in OCaml (or Menhir)
  • Use ADTs and pattern matching for AST design + evaluation
  • Validate language usability with real domain experts
