Buy or Wait?
A deterministic financial affordability and cash-flow decision engine.
Built a deterministic Python engine that reconciles transaction lifecycles and recurring payments, simulates daily balances with debit-before-credit ordering, and enforces strict minimum-reserve constraints. Currency calculations use Decimal arithmetic.
The supplied résumé reports 51 passing automated tests, including 15 adversarial scenarios covering conflicting transactions, missing amounts, retries, and payment-plan edge cases, with strict output-schema validation. These are reported project test results, not a live CI status.
