Aquila — Car-Insurance Pricing & Underwriting Engine

The problem

Car-insurance pricing has to be three things at once: accurate, fair, and defensible. Black-box models struggle on the last one — when a regulator or an underwriter asks “why this price?”, “the model said so” isn’t an answer. Pricing that can’t be explained can’t be trusted.

What I built

Aquila is a deterministic, configuration-driven pricing and underwriting engine — FastAPI and Vue 3 on PostgreSQL. Because it’s rule-driven rather than opaque, every price is fully traceable: you can follow a quote from the raw risk factors to the final number, step by step. It’s claim-aware and fault-weighted, so history and responsibility shape the price the way they should.

The result

Pricing that underwriters and regulators can actually inspect — the same inputs always produce the same, explainable result.
