How many years have you been working with Java and Spring? What projects have you done? What has been most memorable?

I have been working with Java and Spring for about 5 years. Mainly involved in developing enterprise applications for automating business processes, including ERP systems and CRM.

The projects were diverse: from order and warehouse management modules to integration with external services via REST and SOAP. I often used Spring Boot for rapid microservice development and Spring Data for database interactions.

The most memorable task was optimizing the performance of a large ERP module, which required deep understanding of caching, transactions, and asynchronous data processing. This significantly reduced response times and increased system stability.
