Limitations

This app was created as a tech test, in the interest of time some things have been left as essentially dummy code, to enable producing most of the solution in a shorter space of time, documenting the main limitations here:

• Only Handler layer logic has been implemented properly, the DB layer simply responds with dummy code as opposed to actually querying the DB and returning a real response. The method signatures themselves would remain unchanged and the DB layer could and would be implemented independently
• No testing is done on any part of the application
• Passwords are not encrypted etc. (they're not even stored) and just compared as plain text
• authentication is done using an access-token cookie, rather than using an Authorization header, not necessarily a limitation just clarification of the feature
• filtering results not implemented (handler logic does filter out previously swiped profiles, logic doesn't exist at DB layer to check for them correctly)
