User stories
As Jimmy/Olivia,
I can register in the platform as mentor, mentee or both
So that I can start using the platform

Additional information
Here is a sample UI flow mockup (feel free to change/simplify - the goal expressed as user story above is more important than complying with the mockup)

For info on typography and for design discussions, contact @marcidenmark

Acceptance criteria
To consider this story completed, the following is expected:

• a potential platform user can create their account - the account is persisted (i.e. connect with the API)
• the user's profile is initialized - some minor identification info is enough, such as name(s); with this info we can personalize the experience
• the user's type - mentor, mentee or both - is registered and persisted. Use the API
• (nice to have) the user's profile can be opened and changed at a later stage i.e. the last screen has its own address e.g. /profile

Anything outside of the points above is up to the developer

Open questions

• Consider the validation that the API does e.g. a user with a given username might already exist. Contact @sibsmc for up-to-date info on what the API does. For this story it is ok to handle API failure very crudely e.g. saying "something went wrong, refresh the page" is ok, validation can be subject of another story.

Suggested tasks
Each display above can be a separate task taken by different people. Calling APIs to persist information for each screen (applies to 2 and 3) can be one more task each.
The flow in the end can be an integration task.
All these can be taken by different people - to make it work, each page should be hosted on its own url e.g. use the react router. Here is the suggested list in detail and actionable

• Create landing page without buttons - first screen in the mockup.
• Create user registration form as layout - second screen, it is ok the button signup to only show an alert like "In some time this will work, have patience"
• Register a user from second screen via the API. On success, it is ok to have an alert like "Yay, we know about you now. Stay tuned!" Consider the validation notes above in section Open Questions.
• Create profile page as layout - third screen, it is ok the button to save to only show an alert like "Eventually, your profile will include ..." and dump the collected information from the form.
• Update a user's profile via the API - third screen. Consider indicating success somehow. Consider what will happen if the API call fails - similar to the validation notes above in section Open Questions.
• Integrate it all - add the buttons on first page, add other page transitions.
