NodeJS Developer for AWS Neptune Optimization

I'm in need of a skilled NodeJS developer to enhance my application that interacts with an AWS Neptune database using Gremlin. The primary aim is to optimize existing database queries to achieve faster execution times and to reduce the high resource consumption currently being experienced.

Key responsibilities:
- Optimizing existing database queries for speed and efficiency
- Ensuring seamless integration between the application and the database
- Assisting with refactoring as the codebase grows

The ideal candidate should:
- Have a solid understanding of both NodeJS and Gremlin queries
- Possess experience with database insertion and efficient querying
- Be able to work within an existing codebase and help refactor as needed

The ultimate goal is to improve the integration between the application and the database, specifically aiming for reduced latency. If you have a passion for building efficient data-driven applications, I would love to hear from you. Please include examples of your past experience with NodeJS and database integration in your application.
