Build a node.js webservice connected with Opensearch

I am searching for an skilled developer for a webservice with around 6 endpoints at first saving documents and nested documents in Opensearch (fork of Elastic). Node.js, Opensearch and Git should be installed and configured (3 nodes for Opensearch and 1 node for the webservice and git) on dedicated Ubuntu Cloud servers (blank installations). The Node.js webservice should be developed and the code should be documented inline with redoc. The source code should be accessible.
