Wafi code challenge

Technologies

• Python
• Django and Django rest framework

Development Set up

• Clone repo fit clone https://github.com/esiebomaj/wafi-test.git
• create virtual enviroment python3 -m venv /path/to/new/virtual/environment
• activate virtual env path\to\venv\Scripts\Activate
• Install requirements pip install -r requirements.txt
• start django server python manage.py runserver

Endpoint

• api/add_user to add a user to the system
• api/deposit deposit money into a users wallet
• api/withdraw withdraw money into a users wallet
• api/transfer transfer money from one user to another

Some Considerations

• I used serializers in drf (to be able to quickly validate request body)
• I used drf function views so that we can clearly visuaize the logic, since this is a test
• To achieve an InMemory solution, I used a dictionary to represent the users db. In a real world senario this would be table of a relational db

Open to talking more about other implementation details
