On a glance:

In the last years I’ve worked with small teams on web projects. As I came from the administration side, it was naturally for me to do the backend work, although I’m familiar with frontend technologies, too. I would say I’m a intermediate to upper intermediate programmer and an advanced administrator. I’m eager to learn new technologies and thoughts and I’m proud of my fast learning skills.

Currently I am employed as software engineer at SysEleven GmbH in Berlin.

A short overview over my last projects

artflakes.com

artflakes.com is a print-on-demand online shop with attached social networking features operated by myGall GmbH in Berlin. I was responsible for backend development and business-feature integration like vouchers, stickers and integration of
social networking platforms. The site is based on Ruby-on-Rails, but it relies on node.js services for separated functions.

amicron_web

A product of the Amicron GmbH, thought to be a web-interface for their invoice-managment software. I came to the project after it was run by two students over 2 years. Implemented a big featureset and build a spec-suite to steady the code before the project got frozen.

technoload.com

I came to the project as a sub-contractor of weXelwirken. technoload.com was a online shop for various digital goods. I’ve implemented the main parts of it’s functionalitz´y of the php side (Upload, Processing and Representation). Afterwards I became a contractor of the customer himself. I’ve redesigned and relaunched it in Ruby on Rails and implemented an additional featureset the customer wanted.
