Looking for a new challenge!

[UPDATE: I am right now REALLY busy setting up a “new” part of the company in Gouda. So “Jobhunt 2014” has been put on hold for a bit ;) But interesting challenges are always welcome]

Due to the unfortunate event of the office I work at closing down and the company’s other office being 105km up north I’ve started looking for a new challenge. Warning this post is going to contain a lot of “I”‘s

I have 12+ years of experience in web development.  My compatriots are the PHP and other parts of the LAMP stack. I love to tinker, doodle and the other things. (See my twitter/google+/blog)

Besides that I also love working on mobile applications in iOS and Android. I’ve built a few apps along the way teaching myself Java and Objective C. (Time to learn swift!)

I’ve worked in the hosting business for over eight and half years.  And I would like to stay in there.

I flourish in close knit development teams where I can teach people new things and learn new things.

I’m looking for something in the south western of the Netherlands (Zuid Holland) preferably near Gouda.

But leaving the Netherlands completely wouldn’t make me sad ;) Working from home would also be an option.

For job offers and things contact me on Google+ , Twitter or via email. I can send you my CV or code samples upon request.

Save time rendering XSL(in php), Use an XSL builder

I love XSL. Its a wonderful tool for rendering HTML,XHTML,XML. Imports improve readability and helps you organize your XSL’s in an orderly fashion. But lets face it: Imports are a bit slow especially on networked storage like NFS.

I tried searching for a decent solution. But could not find one.

So I built an XSL builder for my platform(artist community platform) to reduce the time taken rendering from XML to HTML using XSL. It succeeded in lowering the time it takes to render by as much as 25 to 35% on the production site.

It also includes a nifty way of building  different xsl files that contains only the templates you need to increase speed even more. (check out the README)

Now I have both flexibility (XSL is awesome!) and a lot more speed.

Its open source!(GPLv3) (copyleft , so if you have any changes you made, please send them to me )

You can download it here

It contains both a CLI version and the class that does the building (For platform integration!)

CLI version

An example of how to use the CLI version:

./xslbuildercli.php input=/full/path/to/your/xslfiles/index.xsl

This will return the built XSL to stdout. (more examples on how to build to files and how to use the modes to create seperate files for seperate uses, check out the README)

Just the class

If you plan to do some other cool stuff like online XSL editing this might be interesting.


$newXSL = xslbuilder::buildXSLFile(‘/full/path/to/your/xsl/index.xsl’);




Have fun!

Android Experience 2010

Whoa it’s been a while since I posted anything here. Anyway I’ll be going to Android Experience 2010 in Amsterdam on the 24th of march. And looking forward to it already :) Having developed 2 android apps by now (One for shortner and one for my employer) I’m really looking forward to swapping some ideas with other Android devvies. (That is if this isn’t an event filled with non-devvies :D But only time will tell with that ;) )
