Owned & Operated

Hi! We are Mark van der Waarde & Danny Schipper and we love the web. We are the owners, proprietors and sole operators of Alsjeblaft!

We're experienced web developers with a knack for design & typography. The two of us have been cranking out web sites for a living since the Dot-com boom.

Tools of the trade

We work for (and with) a variety of clients – graphic designers, agencies, start-ups, bands, stores, corporations and charities.

While building beautiful, responsive web sites, applications & banners our tools of the trade include (but are not limited to) Photoshop ®, Illustrator ®, HTML, CSS, PHP, MySQL, Textile & jQuery.

We used to work with Drupal & WordPress, but have since shifted our focus to Jack – a PHP5-based library with a user friendly CMS back-end. Jack's been in development since 2009 and is currently serving dozens of websites!

Fresh produce

Listing all clients and projects we've worked for would be impossible, but we do like to highlight a few we're particularly proud of.

* All sites are rocking Jack,
unless noted otherwise.

Our rolodex includes:
