Complex Logic Engines

Ingest · Evaluate · Decide

For the work that lives in someone's head: pricing rules, eligibility checks, dispute logic, underwriting. We encode the decision, test it against your history and put it in production with an audit trail.

The problem

One person knows how you price, qualify or adjudicate — and when they're out, the work stops or the answers drift. The logic is too nuanced for a spreadsheet and too important to guess.

What we build

Inside the engines.

Document ingestionPDFs, statements and forms parsed into structured data.
Rule + model hybridDeterministic where it must be, AI where judgement helps.
Audit trailEvery decision explainable, with the inputs that drove it.
BacktestingValidated against your last 12 months before go-live.

How it works

From scope to live.

1

Extract the logic

We sit with your expert and write down every rule and exception.

2

Build the engine

Deterministic core plus AI judgement, versioned and testable.

3

Backtest on history

Run it against a year of real cases and reconcile the deltas.

4

Deploy with an audit trail

Live with every decision logged and explainable.

Tools we use

Node.jsPythonPostgreSQLRedis

This is real engineering, not a no-code toy. Python and Node carry the logic, Postgres holds the record of every decision, and Redis keeps it fast at volume — because a decision engine has to be both correct and auditable.

FAQ

Questions, answered.

Is it AI or hard-coded rules?

Both, deliberately. The parts that must be exact are deterministic; the parts that need judgement use a model — and every path is logged.

How do you prove it's correct?

We backtest against your last 12 months of real cases and reconcile every difference with you before it goes live.

Can we explain a decision to a regulator or customer?

Yes. Every decision stores its inputs and the rule or model output that drove it, so it's fully explainable after the fact.

Who owns the engine?

You do — source code, database and logic. It runs in your infrastructure and you can hand it to any engineer later.
