Doga webdevelopment studio


Sterker samen. De samenwerking was er al jaren, maar het is nu ietsje officiëler: voortaan trekken 37631b & Alsjeblaft samen op onder één vlag.


We are Mark van der Waarde & Danny Schipper and we the internet. We are the owners, proprietors and sole operators of Alsjeblaft (est. 2009) & Alsjeblaft, LLC.

We're experienced front and back end 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

While building beautiful and 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've worked with the APIs of Mailchimp, Mollie & Chainels, built a platform for shopkeepers and created banners that run on bank ATMs.

All our sites proudly run on Jack! Jack – a PHP5-based framework with a user friendly CMS back-end. Jack's been in continuous development since 2009 and is currently serving over 100+ websites!


We work for — and with — a wide variety of clients, amongst with are graphic designers, agencies, start-ups, bands, shopkeepers, b2b corporations and non-profits, like:

Fresh produce

We can't possibly list every single website we've worked on, but we do like to highlight a few we're particularly proud of.

Your name here?

All our sites, webshops & apps are build on Jack.


Jack is a home-grown Content Management System (CMS) that makes managing your website a breeze. We built Jack because we think you shouldn’t have to be a rocket scientist to run a website.

Jack isn’t particularly demanding either. It runs on Linux, Apache, PHP5 and MySQL, a software bundle which is supported by pretty much every hosting provider under the sun.


Website, shop, blog, or intranet? Nederlands, Français and/or 普通話? You betcha! News archives, shopping carts, sign ups, Instagram feeds, anything is possible. You dream it, we'll build it. Jack’s modular design makes it a viable platform for a plethora of websites. Don't just take our word for it: Jack's currently running on over a hundred servers!


And the best thing? Using Jack is one-hundred percent free. No hidden fees or subscription costs. You pay us to design and build your custom website, you get to use Jack for as long as your site is live. Free of charge!
