JavaScript Developer

Help us develop our website and educational apps so that we can achieve our aim of making maths relevant and physically active and raising attainment.

Numberfit is a social enterprise that works to make Maths learning fun and engaging for children across all age groups. We are looking to grow our reach, and with this our team.

Numberfit has two key product areas: Numberleague and AnswerMats. The Numberleague is a series of Maths minigames/activities where teams of students accumulate points which are then displayed on a leaderboard. There are three variants of the Numberleague: a free trial for schools to try the service, a competition in which schools compete, and a version for the home, which can be used to practise and revise topics. AnswerMats is a physically active way for students to complete Maths worksheets. Students have packs of cards and a physical board, an AnswerMat, on which they pair questions with their corresponding answer.

Some of the tasks we are looking for JavaScript Development volunteers to help us with are:

-Programmatically creating Maths question cards, which are then collated to form Maths worksheets in PDF format. These PDFs are distributed online and as physical Maths question packs. PDFs are created using a Node.js library called PDFKit.

-A mixture of front-end and back-end JavaScript tasks. Back-end tasks will usually use Node.js. Products like the Numberleague are serverless (using HTML, CSS and JavaScript) but, like other applications with a backend, use DynamoDB databases hosted on Amazon Web Services (AWS).

We have plans for doing other projects in the future, such as mobile apps, a platform for interactive videos, the use of wearables… All your ideas are welcome, and we hope to work on those products soon too.

You will be working with our internal developer and senior team, who will provide you with instruction and guidance.
