Banana Brokerage – Institutional Trading Gateway
A production financial brokerage engine managing multi-party settlements between farmers and institutional traders, featuring ledger rollback integrity, sub-second calculations, and automated billing.

What Was Broken Before
Agricultural commodity brokerage traditionally relies on paper registers, leading to calculation discrepancies, slow settlement cycles, and high financial dispute rates.
- Manual tare and commission arithmetic errors across thousands of daily crates.
- Difficulty tracking multi-party running balances between farmers and commission agents.
- Lack of audit trails when previous day transactions required adjustments.
The Solution We Engineered
We engineered a cross-platform trading terminal with an atomic ledger integrity engine that supports reversible edits and guarantees mathematical consistency across all party accounts.
- Flutter desktop terminal optimized for high-speed numeric keypad data entry.
- Reversible edit architecture automatically adjusting dependent account balances.
- Cloud synchronization ensuring instantaneous visibility on mobile companion apps.
