As a project manager, I'm seeking a skilled developer to aid in implementing the Financial Information eXchange (FIX) protocol message parsing in NodeJS. Your skills-set will also include developing custom FIX message handlers.

Key requirements:

- Expertise in Node.js is essential.

- FIX protocol proficiency, particularly in message parsing and custom handlers.

- Possess innovative problem-solving skills because I'm yet to select the library for parsing and handling FIX messages; therefore, your advice will be sought.

This task requires an experienced coder with a background in financial applications and data handling. To illustrate your understanding, please include examples of FIX protocol implementations you have completed in your bid.
