Hello,
I have gone through the presentation you have linked to and I am a professional Moodle mobile app as well as Moodle plugins developer with more than 7 years of experience.
I have done lots of work in Moodle considering learner engagement, learning analytics, gamification, customizing Moodle mobile app in all the projects.
I can customize the Moodle mobile app 3.5 as well and already did 3 projects in it.
Let me know if this is something you want to discuss further on.
Looking ahead for a long term relationship with best outputs always.
