  • An eCommerce Site (Development)

    A simple React.js, Redux, React-Router, and Webpack SPA.

    Used Redux for state management and React-Router to manage routing.

    The main design consideration was to use semantic URLs that accurately describe the state of the application. This is to improve the SEO as well as the user readability of the URLs especially if they share their links.

    The search results along with any filtering will be captured in the URL.
    For example, a querystring of
    would return tools that are less than 66 dollars and sorted in ascending order.

  • A Clone of Digg (Development)

    This is a mini project to make a clone of Digg. It uses React, Redux, and Webpack

    • You can find more at my GitHub site:

    In this application, the focus was on the smoothness of the user interaction. When new threads are added the transition from submitting a thread to the thread appearing on the listing is seamless.

    There is also a graceful handling of errors. For instance, exceeding the character count will lead to a gentle reminder of the exceeded count as well as a subtle vibration when the user persistently tries to submit the thread.

  • Cashback Auntie (Development)

    Out of an interest in keeping track of cash back from credit cards, I made this application that allows you to enter your expenses and making note of the card used in the transaction.

    The application will calculate the amount of cashback the user has accumulated and is able to give a recommendation on which card to use in the next transaction based on the prevailing expenses made and the type of transaction that the user plans to make.

  • Art Hop (Development)

    An application for users to discover art spaces and events.

    This application was made using Angular with the back-end in Drupal. It has now since been rewritten in React.js and Ruby on Rails.
