What interesting tasks were there on the project?

In one of the projects, I had to implement a complex data caching mechanism considering multithreading and high load. The task was to ensure data consistency and minimize response time while multiple users accessed the system simultaneously. For this, I used ConcurrentHashMap and optimized synchronization algorithms, which significantly improved the system's performance.

Another interesting task was implementing a microservices architecture, where I was involved in developing and integrating services using Spring Boot and Kafka for message exchange. This required a deep understanding of distributed systems and ensuring reliable interaction between services.
