  • Sonder's Back-office Application

    Working with a company on a mission to revolutionize the hospitality industry, my role at Sonder was to make the support agent's work as efficient as possible.

    The main tool support is using the back-office software, which my development team and I collaborated with the design team to re-write the application's front end and provide the necessary API to support it.

    Shortly after the product launch, we saw efficiency improvement with an estimated value in time savings of around $400,000 a year.

  • Charlotte Cardin's Merch Store

    The Merch Store is an eCommerce platform promoting Charlotte Cardin, the Canadian singer, by selling merchandise such as shirts, hats, shoes, and albums.

    A four-person North American company that was in charge of merchandising previously had to contact a developer any time a change was required on the store pages.

    I delivered a Shopify website that seamlessly transitioned to the buyers as the existing styles and links were perfectly ported from the current site. In addition, products and branding can now be maintained by anyone without a developer's assistance.

    Since then, the store has been serving an average of 100 daily orders and many more on new album releases.

    Vincent d'Amerique's Boutique is an online eCommerce selling clothes for men.

While collaborating with a designer and another developer on the migration and rebranding of the site, my contribution was to reduce maintenance costs by 80 percent using Shopify.
