Barney Carroll

Front-end web developer

I’ve been designing and building websites professionally for over 6 years. I started making sites as a teenager when Netscape Composer came out. Later I got a job designing and implementing look & feel for websites at an information design agency. From then on my increasing exposure to browser quirks and nifty plugins led me to specialise in the technical aspects of implementing designs for the web, until I became a pure front-end develoer.

I hand-code Javascript, HTML and CSS, and pride myself in a thorough knowledge of implementation particularities from IE6’s layout issues and proprietary filters support through to implementing bleeding edge HTML5 and CSS3 techniques safely and making the same code base render elegantly across the feature- and smart-phone spectrum. I’ve forever got an eye on the latest developments in the open source community and track bugs for fun. Accessiblity, progressive enhancement, efficient and modular readable and reusable object-oriented code are always on my mind.


  • JS, HTML & CSS expert
  • Critical UX and GUI design sensibilities; can design as well as build
  • Rapid prototyping, iterative design and thorough testing make the world go round
  • Extensive knowledge of popular front-end libraries, plugins and techniques: will only re-invent the wheel if it’s within budget
  • Happy to operate in agile, waterfall, or just-get-it-done-by-yesterday working environments
  • Familiar with PHP, .NET and Python back-ends
  • Flexible with software. Windows, Unix or Mac; plain text code editing committed via command-line through to rigid Visual Studio workflows; Adobe CS expert
  • Versioning is great: SVN, GIT, TFS — as long as it’s systematic
  • Just for the bots: HTML5, CSS3, JS, XML, XSLT, JSON, jQuery, underscore, AJaX, MVC, GUI, UI, OO, FTW, ETC.


Holler []

Front-end developer
July 2012 – October 2012

Holler is the digital wing of Leo Burnett, an international creative agency producing extensive campaigns for huge consumer brands.

I was contracted to develop cutting edge web applications making clever use of social media, and interactive multimedia elements.

Holler prides itself in developing concepts to the bespoke aesthetic standards that extend leading brands, so the work is subject to exacting UX and design standards that push the envelope of front-end web technology, and demand tight front-end application logic to produce deep and extensible experiences.

Examples of work for Holler:
Opera di Peroni is a joint venture between Peroni and Go Opera to produce bite-sized pop-up opera in urban settings, to allow time-honoured classics to become casually accessible. The application uses HTML5 video to present an interactive playback of the event, calling in social media reactions in time with the experience.

Red Bull’s Culture Clash festival wanted to celebrate mix-tape culture with a modern twist to enable the public to filter through the music that inspired the performers and in turn produce their own set-lists to be viewed and played online — and for one such set list to be played at the festival. The application integrates with Spotify to enable users to explore and share the music that makes the festival.

Virgin Media []

Front-end developer
May 2012 – June 2012

I worked as part of a discreet development team within Virgin Media developing the second major iteration of Virgin Media’s video-on-demand and remote record web interface.

Making use of a rigorous Agile BDD development process, the project consisted in building functional user interfaces based on supplied designs to rebuild the live and catch-up TV experience, including social features, from scratch to match cutting edge user experience expectations.

This assignment consisted of work on a consumer-facing product that is not yet publicly available.
