BlockyDevs was responsible for the architecture and implementation of the scalable infrastructure for the payments platform. This included taking ownership of the design decisions and ensuring that the system could handle increased loads while remaining compliant with regulatory standards.

The architecture featured a microservices-based design, allowing for independent scaling of components such as transaction processing and user management. Key decisions included the use of containerization for deployment and the selection of a cloud provider that offered robust compliance features. Tradeoffs were made between speed of deployment and thoroughness of testing to ensure reliability.

Risks were identified through a detailed risk assessment process, focusing on potential compliance issues and system vulnerabilities. Reliability was approached through the implementation of monitoring and alerting systems, while correctness was ensured through extensive testing and code reviews. Scenarios such as service outages and data breaches were considered, with contingency plans developed to address these risks.
