NodeJS Proficient Backend Coder Needed

I am looking for an experienced backend coder with proficiency in MongoDB. Understanding other languages such as Python, Java and PHP is a bonus but not a necessity.

Essential Skills/Experience:

- Demonstrated experience with MongoDB
- Comprehensive knowledge of database systems
- Backend coding expertise

Your primary task will be working with the MongoDB database system, so past experience with it is non-negotiable. I prefer a coder who has knowledge of other database systems, and a solid track record of handling backend code.
