Hi,
NodeJS was only released in 2009, and it was adopted by the market much later, so I'm sure you won't find anyone with 10 years of experience in NodeJS :)
I head the backend engineering team for a startup, and I have plenty of experience in debugging and maintaining complex back-end APIs. I would love to hear more from you about your project. Please drop me a message - I would love to discuss this at a time of your convenience.
Regards,
Sahil
