Tell me about the project at Tochka Bank.

In a project at Tochka Bank, I participated in developing a high-load microservices solution for processing financial transactions and client data. The main stack included Java with Spring Boot, Kafka for asynchronous communication, and PostgreSQL as the primary database.

Tasks involved optimizing service performance, ensuring data security, and integrating with external APIs. An important aspect was building a fault-tolerant architecture using containerization (Docker, Kubernetes).

For example: I implemented a payment processing service using the CQRS pattern and event-driven architecture, which increased scalability and simplified business logic maintenance.
