Hello there,
Very exited to see a project like this. Just recently I completed a project just like this for YuAcademy who are specialized in providing online courses for business & 'elite exams attending' students in India. This project is just similar to your requirement but they required it for different platforms including Android and Ios mobile devices. We took many LMS including codementor and Udemy for reference and we came up with an amazing solution.
I extensively used AngularJS to achieve this finally and I am exited to see a similar project here. Yes. My experience with my previous project helped me to find out the hurdles and to correct them. Just at the right time I am proposing for a similar project. With 100% confidence I am writing to you.
What I can provide: I can provide you a fully functional, well designed, fully tested for UX website, that even surpass codementor or Digital-tutors. I will send you some of my earlier POC designs and functional websites. P.S: These are POC I used for my previous project and I am using them here, as my previous project is not yet live, I cannot mention it here (NDA, you know).
If possible please share your API structure and pattern which helps me to build a robust technical architecture.
Don't forget to take a look into my portfolio, which will depict my style and approach in your project.
P.S: I will send you a detailed proposal that includes all the functional description as word file. Stay tuned.
I request you for a Skype conversation by which we can understand about the project and of course each other better. Hope to hear from you soon. Cheers.
