Expert database developer

A good database developer who can speak and write good English required to write optimized, highly performant (heavily stressed) queries for AWS based databases - CockroachDB (very similar to PostgreSQL) RDBMS, Symas + LMDB (LDAP), Couchbase or OrientDB (NoSQL to store encrypted compressed JSON) and AWS Quantum (which uses PritiQL - slightly modified SQL). We are using Apollo GraphQL server to connect the databases.

1. The development code was done on PostgreSQL and now needs to be migrated to these databases for production.

2. Write a small number of scripts for AWS Quantum through API's. PritiQL is almost 100% SQL-compatible but will need SQL generated by any DB management tool e.g. DBeaver to be tweaked to run correctly. [login to view URL]

Likely 2 weeks of concentrated work

Квалификация: NoSQL Couch & Mongo, PostgreSQL, SQL
