Birdie Developer Test

We would like to thank you for taking our developer test. We understand that candidates will often have many of these tests to complete, therefore we think it's important to cut straight to the important stuff.

About this repository

We've gone ahead and created a boilerplate that mostly corresponds to the technical stack we use at Birdie. The backend/ is a barebone Express server and the frontend/ has been generated with npx create-react-app frontend --template typescript. This saves you from having to create boilerplate code, but you are free to decide to use only parts of it, for example:

  • If you want to use Redux, you can use npx create-react-app frontend --template redux or npx create-react-app frontend --template redux-typescript.

You are also free to make other technical choices, for example:

  • Use Redux Thunk, Redux Observables, Redux Saga...
  • Use Express, NestJS, Loopback...
  • PostgreSQL, MySQL...

Although we do encourage you to be pragmatic and prioritise delivering value over fine-tuning your technical stack.

Context

At Birdie, our app allows care givers to record observations of older adults receiving care, we name them care recipients.

These could be anything from the recording of their mood (happy, sad, bored, confused) to what they drank today (1 pint of water).

Each of these observations are recorded as events in our database. Here's an example of a mood observation recorded in this event format:

{  
   "id":"decaa026-2ce5-49cb-aff9-92326b85a98c",
   "event_type":"mood_observation",
   "visit_id":"39b94aab-cc35-4874-807f-c23472aec663",
   "timestamp":"2019-04-23T10:53:13+01:00",
   "caregiver_id":"4786d616-259e-4d52-80f7-8cf7dc6d881a",
   "care_recipient_id":"03f3306d-a4a3-4179-ab88-81af66df8b7c",
   "mood":"okay",
},

Here's a quick explanation of the base properties:

  • id: Uniquely identifies the observation.
  • event_type: Title we use to categorise our events.
  • visit_id: Observations are traditionally observed during a visit between the caregiver (carer) and care recipient. This ID identifies that visit.
  • caregiver_id: Identifies who the caregiver (carer) was that made this observation.
  • care_recipient_id: Identifies the care recipient this observation is for.

On top of that, there can be additional properties based on the event_type:

  • mood describes the mood of the care recipient as reported by the caregiver

The database (we should have sent you credentials) contains some of these observation events, within the events table.

Challenge

Display the information to a family member

Your challenge is to clone this repository and create a small web application to visualize these observations, so that looking at it is valuable to a family member of this care recipient

This could mean presenting it in the following forms:

  • A table
  • A graph
  • A timeline

Or any other way/combination of those. We are test driven here at Birdie so please make sure you write tests to validate your work.

Deliverables

  • Put your code on Github and send us the link to the repository
  • Deploying the code to a platform like Heroku is a great plus.
  • If you are unable to deploy your code please send a recording of the application working

Set up

Here's the technical stack this boilerplate was made with:

Front end
