Here are some projects I've worked on

• Pivio Platform
  At PV01 I was head of development of Pivio, a Django application which deployed bonds to Ethereum blockchains, with a UI for investors. At the heart was an event driven system to process blockchain events, updating data in a Postgres database and reflected in real time to end users via HTMX. To increase release frequency and application robustness I created an E2E test suite with Playwright, testing the whole bond lifecycle including interactions with MetaMask.
• Scan to Listen
  'Scan to Listen' is a personal project I built with React-Native and Python. The mobile application allows users to scan the barcode of a book to find the corresponding audiobook, as well as CDs and vinyl to find the matching album on Spotify. The app was available on the Android Play Store for three years and received hundreds of active downloads. It also featured as the top post of the week on r/reactjs. You can read more about the project in this blog post.
• Django Identity and Access Managment System
  I designed and implemented a unique cookie-based authentication system for Django applications hosted on the same sub-domain. This system allows users to easily Single-Sign-On to multiple applications, centralizing access management in one place. This project was completed within seven weeks.
• Z-Connect
  Whilst at zoetrope.io I contributed towards the Internet of Things platform Z-Connect, this was the versatile backbone of many IoT projects, with modular Python plugins and reusable React components for both web and mobile apps. This project has been open sourced.
• Hello-Novo
  While working with e-on as a client, I worked within a team of four to develop an air conditioning control system. This project included the creation of a hardware-in-loop testing system for an IoT gateway, infrared device, cloud software, and mobile app. The testing system used 'Appium' to simulate user input and automatically test the user setup process, reducing the need for manual testing and improving the reliability of the product. You can find more information about this project in the blog post I wrote on the topic.
• Ping!
  Technical lead on a news distribution system for the Centre for Community Journalism in which hyperlocal journalists submit news stories to the system via a Django Rest Framework API. This was integrated with a bespoke WordPress plugin which required intricate interplay of PHP, HTML and JavaScript. See here for more information.
