About the Project
The project is developing and integrating a modern payment platform for secure and reliable payment processing and interaction with external systems. It includes scalable microservices and asynchronous transaction processing, with a focus on resilience, security, and high availability.
Responsibilities
•Design the target microservices architecture for banking and payment solutions
•Define service boundaries and areas of responsibility for individual components
•Design microservice communication using REST, gRPC, and Kafka
•Develop integration architectures for internal and external banking systems
•Design synchronous and asynchronous interaction scenarios
•Design solutions for high availability, scalability, and high-load requirements
•Develop and maintain architecture documentation using C4 and UML
•Define API contracts and integration interfaces
•Define approaches to API security and inter-service communication security
•Design the use of Docker and Kubernetes within the solution architecture
•Define strategies for error handling, retries, and failure recovery
•Participate in the architectural analysis of existing banking systems and integrations
•Make architectural decisions and document them in technical documentation
•Advise development teams on implementing architectural solutions
•Assess technical risks and the impact of architectural changes on the existing system
