Accounting & Jackpot Distribution Dashboard for Gaming Venues
Operational Challenge
Managing gaming venues requires daily reconciliation across thousands of machine intake transactions, payout distributions, and progressive jackpots from multiple physical venues. Manual reconciliations caused accounting delays, settlement discrepancies, and compliance friction during gaming authority audits.
What the Dashboard Solves
Collaborative engineering of an operational financial dashboard on a core PHP backend. Pablo designed and implemented the accounting analytics layer: automated totals consolidation per venue and machine, jackpot allocation logic, multi-filter search engine, and structured CSV/JSON export pipelines for accounting systems.
Production Risks & Failures Prevented
- Prevents settlement discrepancies: Atomic calculation and aggregation algorithms ensuring exact mathematical consistency between terminal intakes and prize payouts.
- Prevents database degradation: Optimized SQL queries and composite indexing for heavy historical reporting without disrupting live machine polling.
- Prevents regulatory compliance friction: Full audit logging of transaction events and instant report exports formatted for gaming authority inspections.
