  • Tax Declaration for UK Residents

    An Ember.js-based application to declare and calculate tax returns for UK residents. The logic was all done in the front end, which also calculated the tax return. For security reasons, the calculation was also performed on the back end and cross-checked for validation. In this project, I contributed more to the front end than the back end.

  • Application to Support People with Neuromuscular Diseases

    A web application and a mobile application with information to give support for people who suffer from neuromuscular diseases.

    The web application consists of a Ruby on Rails custom CMS and API, with a frontend developed in React.

    The mobile application in React Native consumes this API, and the application can be used offline.

    Both applications were audited for accessibility and user-tested with blind people to make sure they are usable.

  • Local Producers Marketplace

    I am currently developing a personal project in my free time for my local community—a subscription-based marketplace for local producers to sell their products online only to people nearby and increase awareness and reach. It is a heavily modified Spree project that behaves like a true marketplace. I expect to launch it in 2021 and hope to reach more locations.
