Project Spotlight: Community Fridge KW


Community Fridge KW (CFKW) is a mutual aid initiative with a 24/7 fridge located outside the Kitchener Market. With the core belief of “take what you need, leave what you can”, CFKW serves to increase food accessibility and reduce food waste within its community. Operations include fulfilling food deliveries, initiative marketing, and fridge check-ins with the help of volunteers alongside local businesses and donors that supply food to the fridge. UW Blueprint has partnered with Community Fridge KW since September 2021 to build a centralized scheduling platform to streamline the donation and volunteer process.

The Problem

CFKW lacks an effective way to coordinate donations and volunteer shifts, resulting in lost time spent facilitating communication. For example, a typical flow involves calling a local business for donations, jotting information on Excel, forwarding information to the rest of the admin team, and then contacting volunteers through scattered social media channels. As CFKW scales both internally, within their admin team, and externally, in onboarding more donors and volunteers, they are seeking a consolidated and transparent method to manage multiple user types.

The Solution

Our team built a scheduling platform to streamline donations and remove the admin team from being the middleman between donors and volunteers, with the end goal of increasing both the number of fridge donations and the window of time that the fridge is stocked.

We strived to maximize the value of our platform for 3 main user groups, as followed:

  1. Donors: provide an intuitive way for existing and potential donors to schedule donations ahead of time and to bring transparency via a public donation schedule
  2. Admin: create a single source of truth for managing all donor and volunteer flows and removing admin as the middleman between donors and volunteers
  3. Volunteers: centralize various touchpoints with admin (social media, email, signup.com) for different types of volunteer shifts

To do this, we broke down the development of the scheduling platform into 2 phases: Phase 1 focused on the Donor<>Admin relationship in streamlining donation scheduling and enabling donation transparency. Phase 2 focused on the Volunteer<>Admin relationship by removing volunteer dependency on admin for shift sign-ups.

The Donor Experience

The donor experience is critical for the CFKW team and its users as the food supplied typically goes out in less than an hour.

Donors can create an account to schedule a donation for any future date — the workflow allows them to select the donation quantity, type, and if it’s a pickup or unloading. Additionally, they can request a volunteer and view if overlapping time slots are booked. Donations can happen at a cadence of a one-time drop-off, daily, weekly, or monthly.

Afterwards, there is a centralized dashboard for each donor where they can view all the details of their upcoming donations and easily navigate back and forth through a calendar-like interface. These succinct views provide a cohesive way to create, edit, and cancel donations!

The Admin Experience

From coordinating donations to recruiting volunteers to maintain health and safety fridge checks, the admin team touched every interaction involved at the fridge. The biggest challenge was finding a balance between adding functionalities and automating processes.

Key features of the admin experience are:

  1. Overseeing all donor and volunteer information — this includes all contact information, every donation’s details, and every volunteer shift’s details.
  2. Automating generation of volunteer shifts — whenever a donor requests a volunteer, a shift is automatically generated, removing the admin as the middleman in the search.
  3. Donor/Volunteer shift maintainability — the ability to create, edit, cancel, and fill shifts, empowering admin to retain as much control as they’d like through all of their processes.

The Volunteer Experience

There are two main methods in which volunteers can participate in CFKW operations:

  1. Food rescues — assisting donors with donations, either through picking up off-site and bringing to the fridge or unloading on-site
  2. Fridge check-ins — for health and safety standards, the fridge is required to be looked at approximately 3 times a day, cleaned, and a photo update provided.

Previously, volunteers signed up for these shifts through signup.com, social media, and email. However, now volunteers can see upcoming shifts and sign up with one click, for both food rescues and daily check-ins. Similar to donors, volunteers will be able to manage their upcoming shifts through a chronological dashboard.

Technical Overview

In terms of the technical architecture, the project leveraged React and ChakraUI with TypeScript to serve the user-facing interface that donors, volunteers, administrators, and fridge-users interacted with. The backend endpoints were with Node.js and Express, using a Sequelize ORM for interface with the PostgreSQL database. Automated deployments were done through Docker and Heroku, with Firebase authentication.

The team followed best practices with a staging and production environment, full unit test coverage on the platform backend, and thorough code reviews for pull requests between team members. All the code for the CFKW scheduling platform is open-sourced under the MIT license and can be found here!

Design Opportunities & Challenges

The uniqueness (and difficulty) of this Blueprint project stemmed from the multiple user types and use cases that this platform needed to accommodate. There is a lot of repeated information between the user groups — for instance, we have 4 variations of donation cards:

  1. for the public calendar
  2. for the donor to view their own upcoming donations
  3. for the admin to overview all upcoming donations
  4. for the volunteers to view all upcoming donations that require volunteers.

Many design constraints and considerations had to be juggled across the 4 variations. For example, the top priority for volunteers is the time they’re needed, which differs from the admin, whose top priority is making sure all donations that require a volunteer is filled. Finding the right balance of consistency and distinction required many iterations and collaboration with our client, developers, and designers from other Blueprint teams!

The UW Blueprint team is excited to fully hand off this project to CFKW at the end of April 2022! It was a pleasure to work with a local community organization, and everyone is looking forward to seeing the platform deliver value for its users.

I’ll definitely miss working with all the talented and supportive students on this team, but I’m super excited to see CFKW begin using the platform!

Jessie Peng: Hi! I’m Jessie (1B CSBBA) and a dev for CFKW. Learning more about CFKW’s mission and how our team helps build features for them was really fun and insightful! I learned a ton about backend development for the first time by creating new CRUD services as well as how to write tests/use pgAdmin. I loved pair programming and learning from more experienced developers; every week there was always something new I learned!

Carissa Tang: Hi, I’m Carissa (1B CS) and a dev on the CFKW team. Jumping into the project two weeks before soft launch, it was definitely a challenge quickly familiarizing myself with the codebase. Working on both frontend UI and developing backend CRUD services, I have grown my skills in React/TypeScript. My favourite part of BP has been meeting all the talented and supportive people on the team and working alongside them.
