  • Zigtagz | Find Lost Things (Development)

    I handled the full-stack design and development of an eCommerce website. I have been fully engaged with this project from the beginning—helping the company through branding, design, development, marketing, and SEO.

  • CBRE About Real Estate Blog (Development)

    I rebuilt the blog of the world's largest real estate services and investment firm on a modern WordPress framework. About Real Estate has been enhanced with a whole suite of custom plugins, including one which allows the site to serve different, granular content to each country and region automatically.

  • Think Digitally (Development)

    After a long collaboration of building websites and plugins with Think Digitally, it was time to refresh the company’s own website. Think Digitally builds wonderful user experiences for the web, so it felt only right that our site should be as cutting-edge yet user-friendly as the products we create.

    The site was built on top of WordPress in a gorgeous way to showcase the company’s vast portfolio. A smart two-tier navigation expands when you need it and hides away when you don’t.

  • Interactive Popcorn Simulation (Other amazing things)

    An interactive, popcorn-filled physics simulation built using Matter.js.

  • Pine | UX for Natural Language Processing (Development)

    Treebanks contain a vast number of sentences represented as tree diagrams describing their grammar. These trees are often vital for parsing, translating, or otherwise processing language. However, creating and maintaining treebanks is difficult and time-consuming and the complicated tools that are currently available do little to simplify this task.

    Enter Pine: a purpose-built and open source treebank editor that puts usability and speed at its core.

  • Evora Global (Development)

    A complete SEO and social strategy, alongside design advice, helped Evora (previously Sustainable Commercial Solutions) to go global.

    With a MailChimp newsletter, management of social media accounts, and keyword targeting, we brought Evora onto the first page of Google. Meanwhile, a user experience design refresh helped boost sign-ups to the firm's sustainability newsletter.
