Technologies
Our contribution
- Payment-service engineering: Contributed to a PHP, Symfony and Docker microservice architecture for payment-processing workloads, designed to support resilient operation and independent scaling of selected services.
- Bank and POS integrations: Contributed secure integration patterns for banks and payment methods, plus real-time point-of-sale capabilities that connect online and physical-retail payment journeys.
- Transaction security: Integrated 3-D Secure controls to add an additional authentication layer to online payment flows and support the security expectations that apply to card-processing environments.
Our contribution
- Asynchronous processing and data performance: Used RabbitMQ for asynchronous service communication, Redis for frequently accessed data and MySQL optimization for transaction-oriented workloads.
- Cloud operations and CI/CD: Leveraged AWS SQS, SNS and CloudWatch for background work, notifications and operational visibility. Automated testing, review and deployment workflows supported more dependable continuous delivery.
