Webdevelopment, design & consultancy
Hi! Looks like you were just browsing koenknevel.nl – a site built right here at Alsjeblaft. If you have any questions or remarks, let us know.
We are Mark van der Waarde, Danny Schipper & Antoinette Veneman and we the internet.
We are the head honchos, sole proprietors and smooth operators of Alsjeblaft (est. 2009) & Alsjeblaft, LLC. The three of us have been cranking out web sites for a living since the Dot-com boom.
At Alsjeblaft we prefer to 'keep it simple, stupid'. While building your site we focus on speed, accessibility, clean design, effective typography and making sure your site works on every device under the sun, rather than cramming in the latest web fad. We understand how to communicate your products, services, reports & ideas with your visitors. We can help you tell your story and make your content accessible.
Additionally, we can help you with your English and/or Dutch copy by providing copy editing and translation services at competitive rates. Please click here for more information.
We built a platform for De 9 Straatjes, designed annual reports for Wakker Dier, made statistics on social and physical issues and safety exciting for the municipalities of Rotterdam and Almere & created banners for ING that run on ATMs.
While building beautiful and responsive websites, applications & banners, our tools of the trade include (but are not limited to) Photoshop, Illustrator, HTML, CSS, PHP, MySQL/MariaDB, Textile, Markdown, jQuery, lots of coffee & some good, old-fashioned elbow grease.
All our sites proudly run on Jack – a PHP7-based framework with a user friendly CMS back-end. Jack's been in continuous development since 2009 and has proudly served well over 250 websites and shops!
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, including but not limited to:
Alsjeblaft spans two continents. Danny and Antoinette operate the Dutch office in picturesque Heenvliet & Zwartewaal, while Mark covers the Americas from historic St. Elmo, Chattanooga, Tennessee.

We couldn't begin to list every single website we've worked on over the years, but we would like to highlight a few we're particularly proud of.
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, MySQL & PHP, a software stack which is supported by 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! Free to use and modify as you please. No hidden fees or subscription costs, no fine print. You pay us once to design and build your custom website, you get to use Jack for as long as your site is live, no charge! Did we mention it's free?
