Hi, I'm Alex. Currently I work as a PhD student at Goethe University Frankfurt in theoretical computer science.

Some years ago I worked on a web project which needed to be able to create SEPA files. Back then SEPA was kind of a new thing and just became mandatory and I couldn't find a library that supported everything I needed. So I wrote one myself called Sephpa. Sephpa uses SepaUtilities, a library I wrote and that can be used independent of Sephpa, that is only for validating and sanitizing input against SEPA specifications. Since then quite some people found Sephpa and asked to extend the library to support more file types or some edge cases only relevant in some countries. I added SepaDocumentor to create documentation files of the money transfers.

From time to time it is a lot of work to maintain the documentation and implement new features in a way that it does not break your code too much. I do all this in my spare time, even though I have no project that uses Sephpa for years, since I work at the university.

Beside the SEPA stuff I have some art projects (GenerativeArt and pictor) that create some kind of random images. Have a look and enjoy the images :)

And last but not least, I develop small tools that solve some of my problems I encounter during my work on other projects, e.g. PhpStorm Plugin for better Smarty code folding and a list of filters to improve doxygen documentation for php

If you use and like Sephpa, SepaUtilities or an other project of mine, it would be nice if you consider a sponsorship.

Thanks.
