pumps can send data to the cloud.
September 2017 - December 2018 @ NWB Verlag GmbH
It was my responsibility to develop new products for the German tax industrie.
I created a job platform for tax specialist, with a simple matching algorithm.
July 2016 - August 2017 @ i-SOLUTIONS Health GmbH
The i-SOLUTIONS Health GmbH creates hospital information systems for decades.
As hospitals write letters to resident doctors, I have created a solution to send encrypted and signed letters via gematik network.
July 2012 - June 2016 @ protel hotelsoftware GmbH
During my time at protel, I built a booking interface for the Best Western Hotels, where prices,
availabilities, guests and reservations are syncronized between the Best Western systems
and the protel systems.
As protel wanted to provide more guest information for their customers, I developed a
survey application, which is deeply integrated into the protel core software.
Protel provides a web booking engine for their customers. I created a billing engine,
which is syncronized with the protel ERP system.
Protels software uses over 30000 labels over different applications. I developed a
localisation tool, where every customer can define own translations.
October 2009 - June 2012 @ GHX Europe GmbH
The GHX Europe GmbH operates an order platform in the healthcare industry. It connects healhcare suppliers with hospitals and hospital groups.
As price negotiations can be very complex, I created a price database where these
price negotiations can be visualized.
Some hospital groups buy products worth over one billion Euros a year.
For this case, I created a datawarehouse with an OLAP cube.
Normally the ERP systems of healthcare suppliers and hospitals are deeply connected.
But there are some suppliers, which are working with fax devices.
I created a system, which can generate customized fax documents from xCBL (XML based) data,
and send them to the supplier.
July 2008 - June 2009 @ isc integrated software concepts AG
I created a configration tool for a access controll system, where user data like fingerprints are stored.
