Hello,
I am happy to see that people are trying to learn MongoDB nowadays.
I have been working as a senior 2nd layer technical support engineer for the last 5 years and I've been training the engineers were I worked on MongoDB basics and advanced deployments for a large video streaming platform.
Depending on your time, and on what you need to learn, we can have this done in a maximum of 7-8 days (with a max. of 8hours/day sessions). If more than basic knowledge is required, then it can be extended, but my weekly fee is 150 - 200$.
I can share a training plan that I have been using for new engineers and can share it with you, should you choose to work with me.
Looking forward to hearing from you.
Regards,
Stefan
