• Our next generation payments platform has been developed using Java – specifically leveraging the Spring Boot framework
• Our infrastructure is hosted on AWS; using a mixture of containerization (Fargate) and vanilla EC2
• Our systems are secure and highly available – we have implemented passive and active monitoring and incident escalation using a combination of Datadog, CloudWatch Logs and Metrics, Postman, and Pagerduty
• We utilise GraphQL (leveraging Apollo and Hasura) to open up our rich data model to internal and external stakeholders
• We develop frontend systems using the Vue, Angular, and Ionic frameworks
• We aggregate and analyze logs from all of our systems via the ELK stack
• Our operating system of choice is CentOS and our DevSecOps team is fanatical about security, monitoring, and patch management
• Our infrastructure is immutable and managed using IaC principles via Terraform
• We leverage build automation (specifically CircleCI), and we’re working toward continuous deployment across all environments
• We take advantage of AWS services to meet our various technology requirements:
• PostgreSQL databases run on Aurora Serverless or Aurora clusters managed via RDS
• Redis clusters are managed via ElastiCache
• KMS provides managed security services
• AWS Lambda and API Gateway support our serverless infrastructure; DynamoDB is also an important part of our stack
• We utilise highly durable messaging technologies such as SQS, Kinesis, Amazon MQ and AWS EventBridge
