Developing project Libreflip

Open Source page-turning DIY Bookscanner

I am currently developing an open-source page-turning book scanner called Libreflip. The goal of the project is to create a page-turning book scanner that has complete documentation and is optimized to be easy to be build by others.

I am documenting this project with a videoseries on Youtube and provide regular updates via Twitter and a Facebook Page.

What my customers say about my work.

Ijon is most excellent in situations where he has to decide fast and sticks with his decision. Wether he is controlling a crowd of a couple of thousand people or managing a stage at a congress, he gets it done and works around almost any obstacle.

Ijon arbeitete stets sehr effizient, zielstrebig und sorgfältig. Er bewies ein herausragendes Organisationsgeschick.

Ijon war stets engagiert dabei unser Unternehmen auf breiter Ebene voranzubringen. Er identifizierte sich absolut mit seinen Aufgaben und war hochmotiviert und zeigte ein hohes Maß an Eigeninitiative und Leistungsbereitschaft.

Er verfügt über ein äußerst umfassendes und hervorragendes Fachwissen, […] dabei war er auch höchstem Zeitdruck und Arbeitsaufwand stets gewachsen.

These are some of the many areas in which I can create solutions.

There is just one requirement: I need to use my brain on a daily basis. The rest is negotiable.
