Before starting my own project in company, that use ElasticSearch, i was working on:

2. optimizing PostgreSQL queries
3. rebuild or refactor some old code (big-data logic)
4. creating service that showing goods that are in RabbitMQ queue, even if there was a 10k+ queues. This service using Redis.
etc.

Implemented ElasticSearch in big-data, high-load project.
Created service that working with ElasticSearch and building query for ElasticSearch with options. This service working with all types of fields like integer, text, date and even nested fields.

Created service that user can use for search in ElasticSearch in different ways with different options.

Created user friendly UI for managers, that can choose different fields, with different conditions for search in easy way. Just a few clicks, and difficult query is created, and user already see result of search in attractive way.

This difficult and big-data queries was very fast, not only because of ElasticSearch engine.
