I have 2 years experience working with mixpanel & google analytics as well as with their APIs in Javascript and PHP.
For mixpanel I can go over with you in 1 hour each.
- Engagement (Segmentation, Funnels, Retention, Live View, etc etc etc)
- People (identifying individual users via explore, insight, setting up notifications, etc etc etc)
- Mixpanel API (Sending data from your site/service to mixpanel via Javascript/PHP)
We can customise the lessons based on what you do or dont want to know. 3 Hours is my estimate but it may be less based on what you would like to learn.
