I have enough expertise to help you with any of the following for Elasticsearch. 1.Setting up the elasticsearch server on cloud (your preferred platform). 2.Write python/shell scripts to index the data to Elasticsearch. 3.Re-Indexing the data and migration of server in zero downtime. 4.Creating the nginx server with rules to add it as a security layer to bypass the requests. 5.Any Elasticsearch mapping and query related issues at server level and at the application level.
