A charitable mathematics project founded and run by bestselling science author and maths educator, Simon Singh.
A site for weekly problem sheets when I joined the project, I have worked to bring live webinars and tutorials used by hundreds of students a week. Leveraging AWS AppSync GraphQL Subscriptions, the site offers instant updates for students viewing "Maths Circles" Live streams, joining small group "Tutorials" or interacting with live quizzes in real time.
Sick of sites requiring sign ups, spamming emails and wanted to upsell, I built Card Sign as a simplier alternative to the existing eCard sites.
Built using Remix & DynamoDB, Card Sign offers a simple method of creating, signing and sharing eCards.
