Hi, I'm Laurence Mercer, a senior-level Drupal developer with thirteen years' web development experience and twelve years' Drupal site building, module development, and theming experience.

Drupal, HTML, CSS, CSS preprocessors (including Sass and LESS), responsive design, JavaScript, JavaScript libraries (jQuery, React, etc.), JavaScript frameworks (primarily Angular), TypeScript, Node.js, PHP, Symfony, Twig, MySQL, RDF, SPARQL, Linked Data, APIs (primarily REST/JSON, JSON:API, and GraphQL), mapping solutions (primarily Google Maps, OpenLayers, Mapbox, and Leaflet), and graphics applications (primarily Photoshop and Illustrator).

Development setup and services
Virtual machines (currently using VirtualBox with Vagrant and Puppet), LAMP, WAMP, MAMP, Git, GitHub, and Jira.


I have a comprehensive knowledge of Drupal—a leading open-source CMS—with particular focus on the frontend and Drupal theming.

I've been working with Drupal since version 4.6 (you can find me on drupal.org and IRC as laurencemercer) and have built and themed many Drupal-based sites, including michaeljackson.com and jimihendrix.com.

My work includes day-to-day use of many core, contrib, and custom modules including Views, Display Suite, Panels, etc. and I'm fully conversant with the Drupal API, Devel, Drush, and the command line.

I provide Drupal services for clients across the world, most often working remotely from London, UK. Previous clients have been located in the UK, Australia, Belgium, and the US.


I reply to all work inquiries, quote requests, etc.
