Experience

  • Ery-api (Development)
    https://www.npmjs.com/package/ery-api

    Ery-api is a CLI tool to give you quick access to the API calls you're looking for. It performs the OAuth flow for authorization with all Google APIs.

    The idea is to never have to read API Docs again. Give it a go with:
    npm i ery-api -g

  • HR Chatbot (Development)

    For a business I worked for, I created a Dialogflow based HR chatbot that allowed our team to get quick answers to questions like: "How do I submit an expense?", "How many holidays do I have left?", "What is our policy on XXX?", etc. I integrated it into a slackbot to give everyone in the business fast answers to questions on how we do things.

  • Snoozethat (Development)

    I built a server that allows you to snooze emails, but forwarding an email to, for example, "[email protected]" or "[email protected]" and getting a reply in the same email chain at the specified time. This helped our customer service team stay on top of customer accounts when delayed actions/follow-ups were required (This was before Gmail introduced the snooze function).

  • Language Learning Platform (Development)

    I built a platform that helps you learn a language by translating an epub e-book word-for-word. This allows you to read a book in a language you are learning and always having the translation available if you don't know a word in it. The tool will also pronounce the word for you if you tap it and show you further information, such as the conjugation if it is a verb. As this was a Progressive Web App, it allowed you to read the books when you were offline.

  • Offline Tasks Tool (Development)

    I built a tool that used a service worker to build a Progressive Web App that would work offline. The tool was designed to help you keep track of your tasks by allowing you to snooze tasks until the time came to take care of them.

  • Art Gallery ERP (Development)

    I built an ERP tool for an art gallery that needed to track where certain pieces of art were stored, who had enquired/bid/purchased them and what invoices/communications were logged against them. The tool also had a front-end component that acted as the gallery's online presence.
