    2019 - 2019
    Social News Desk
    • Redeveloped and extended an existing product using React, Redux, and modern CSS during a 3-month contract that allows news stations to create and interact with social media feeds live on air.
    • Led the implementation of pixel-perfect styling from designs provided in Zeplin.
    • Created a component structure and related styles that would allow straightforward reuse and extension for different branding.
    • Developed SASS mixins for the creation of smooth, reusable CSS animations.

  • Lead Web Engineer

    2015 - 2019
    • Led the front and middle-tier development for all of Metail's client-facing UIs.
    • Advocated for and led the change of stack and architecture of Metail's primary product, a virtual fitting room plugin for clothing retailer's websites. This expanded the plugin from being desktop-only to being mobile and native-ready.
    • Layed down the foundation in new codebases to ease local development and provide seamless routes for deploying to staging and production environments.
    • Defined and led the implementation of a JavaScript API to allow ourselves and our clients to perform integrations of the plugin.
    • Led the development of REST APIs to support both customers and retailers.
    • Led both front and backend performance management and improvements. This included latency and payload of the API requests and frontend resources (including optimising for the initial payload), reducing the number of requests and resource caching.
    • Used AWS services to deploy front and middle-tier components to provide our services quickly to tens of thousands of daily users across the world.
    • Worked closely with project managers and designers to outline technical feasibility of mockups and designs, provide time estimates and break up high-level requirements into workable tasks.
    • Actively developed and mentored junior and senior engineers.
    • Acted as the Metail's first off-site developer, helping to outline an effective strategy for remote working. The team subsequently grew to be 50% remote.

    • Defined the architecture for, and led the development of an iframe-based, customizable, localizable virtual fitting room plugin for retailer's desktop sites.
    • Led the development for standalone fitting room sites, such as that for our collaboration with ITV’s This Morning, where it was used periodically on live television and for which we were nominated for the BAFTA for Digital Creativity in 2014.
    • Defined and led the implementation of the build, continuous integration and deployment processes for all front and middle-tier components.
    • Helped build, line managed and led the technical team for the development of Metail’s fitting room UIs.
    • Helped define job specifications, defined tech tests, reviewed candidate CVs and performed technical interviews.

  • The Club HQ (Development)

    I'm a Co-founder and sole developer of The Club HQ, which aims to support grassroots sports clubs by providing a cheap, easy way for them to create a modern website to manage and engage with their members. The site will soon support multiple sports and localizations.

  • Metail's Virtual Fitting Room (Development)

    While I worked at Metail, the primary product was a JavaScript plugin for the clothing retailer's sites. This was a helper that followed the user around the retailer's site and allowed them to create a 3D version of themselves so that they could see what clothes looked like on their body and receive recommendations on which size to buy.

    I defined the architecture and led the front and middle-tier development for this plugin. It was designed to allow us to use a single codebase to support retailer localisations, style, and branding customizations, and work across their desktop, mobile, and native platforms.

  • Takeover the Makeover (Development)

    While at Metail, I led the front-end development for a collaboration with ITV's This Morning, where the standalone virtual fitting room we created was used live on the show each month to find an outfit for a guest for a special occasion.

    The fitting room was used on a touchscreen by one of the hosts, and viewers were invited to try it themselves at home to submit outfits as suggestions for the guest. At the peak, the fitting room supported over 5000 concurrent users.

    For this work, we were nominated for the 2014 BAFTA for Digital Creativity.

  • CrystalEye (Development)

    CrystalEye was a tool I created while doing my Ph.D. to help me gather crystallographic data that had been published in peer-reviewed journals. It started as a web crawler that automatically scraped this data from the journals as it was published before republishing them in a single collection on its own website.

    Later, I further expanded the tool to convert the data to XML for easier processing, added RSS/Atom feeds to allow other researchers easy access to the data, and 3D visualizations and graphs.
