Name one technical improvement made on the project besides business tasks.

One of the technical improvements in the project was the implementation of centralized logging using the ELK stack (Elasticsearch, Logstash, Kibana). This significantly simplified monitoring and debugging, increased transparency of the system's operation, and accelerated error detection.

For example, previously logs were stored locally on servers, which complicated the analysis of distributed services. After implementing ELK, all logs were collected into a single system, where dashboards could be quickly built and keywords searched.

This improvement is not directly related to business logic, but it significantly enhanced the quality of support and maintenance of the project.
