Collaborated in a team of 6 developers to maintain a backend consisting of over 10 microservices of platform for a network of agricultural products stores. The platform's functionality included an admin panel for managing products and different parts of enterprises, product sales online to customers, and collecting statistics.

- Managed the configuration and tuning of Elasticsearch index settings, ensuring data integrity between the primary data store and Elasticsearch;

- Developed the majority functionality for comments service;
