Public Transport: High-Volume Transaction System Optimisation
A major metropolitan public-transport payment platform processing millions of transactions required backend, database and integration improvements in a mission-critical environment.
The Challenge
A large public-transport payment platform processes millions of passenger and financial transactions every day. Its technology provider needed additional expertise to improve system performance, strengthen data integrity, and support reliable release cycles.
Key priorities included:
- Ensuring accurate real-time tracking of passenger account balances as travellers entered and left the network.
- Supporting top-up processing and reconciliation.
- Improving database performance under high transaction loads.
- Optimising service interfaces and data transfers between the technology provider and transport operator.
- Strengthening automated testing to support faster, more reliable releases.
The system was mission-critical to a metropolitan public-transport network, with no room for failure.
Our Solution
Dark Arts was engaged to support the ongoing development and optimisation of the transaction platform’s backend:
- Assisted with development of the modern backend application platform, supporting new feature delivery.
- Provided expert tuning and optimisation of the high-volume relational database platform, improving performance and reliability under peak loads.
- Diagnosed and resolved key database administration issues, improving stability and maintainability.
- Improved the service interfaces transferring critical transaction data between the technology provider and transport operator, ensuring accurate and reliable data exchange.
- Strengthened automated testing and delivery processes, helping ensure quality and reliability in each release.
The work delivered key improvements in system performance and operational robustness, helping the platform handle ever-increasing volumes of public transport transactions.
The Impact
- Improved backend performance and scalability, supporting smooth operation across the metropolitan transport network.
- More reliable data transfers improving reconciliation and reporting accuracy.
- Better automated testing and CI/CD, supporting faster, safer release cycles.
- Helped ensure secure, real-time handling of substantial public transport revenues.
The platform remains a critical part of the region’s public-transport ecosystem, and Dark Arts’ contributions helped strengthen the performance and resilience of this essential financial infrastructure.
