Freelance analyst/programmer based in Berlin, Germany.
In addition to the work I have done for clients, I also have some projects I work on in my own time in order to practise my skills or learn new ones. Please click the name of each project for screenshots and further information about it.

When learning a new technique, I like to document the process for future reference. Here are some guides I have written about various technical subjects. They were almost all written around the same time as I developed the Tech Club web application (see above), so they mainly refer to web development and server deployment.

|Deploy the site||Copy the application files to the new server using FileZilla, then show the necessary steps to get the site online.|
