Client Challenge
A major online ticketing operator faced high server load issues during mass sales, resulting in website crashes, payment errors, and lost orders.
The client also experienced difficulties integrating with multiple payment systems.

Our Solution
(01)Developed the Platform
We developed a fault-tolerant platform for payment processing and ticket sales management.Load balancing mechanisms, a scalable microservices-based architecture, and request caching were implemented to accelerate transaction processing.
(02)Integrated Payment Systems
Integration with key payment systems was implemented, including bank cards, e-wallets, and mobile payments.
Additionally, a fraud detection module powered by machine learning was introduced to identify suspicious transactions in real time.
