Full Stack Developer

Third Space Learning Ltd
Aug 2017 - Oct 2017
  • Architected and implemented the initial frontend version of Mathshub - an online platform that provides different types of Maths resources (documents, videos, daily challenges) for teachers and pupils from Year 1 to Year 6. The content is available on a tier based method.
  • Architected and implemented the initial backend version for Mathshub. All the communications between the client and the SQL Database were made through the thin GraphQL layer which comprised many custom made Types, queries and mutations. Different filters were created in order to deliver the correct information based on the user's tier - eg download urls.
  • Created the SQL Database from scratch in order to store the various resources in a organised manner. I have also used materialized views (that auto refresh through triggers) for different parts of the app to reduce the usage of costly join operations between tables and deliver the information needed by the frontend.
  • Created a bespoke CMS (PoC) offering basic CRUD operations enabling non-devs to create and update Mathshub content making use of the whole GraphQL backend.
  • Architected and implemented an initial version of a custom CMS for updating the Mathshub Database and make use of the graphql mutation in a safe environment while making offering basic CRUD mutations. The stack used was mainly the same as the Mathshub app, which is ReactJs, NextJs, Apollo, Redux, styled jsx and tachyons.
