meinestadt.de Logo

meinestadt.de is the market leader in Germany for job advertisements for hiring employees without an academic degree. With three successive applications, we helped meinestadt.de to offer customers, employees and applicants a smooth user experience when using the job market.

applyNOW provides a consistent native user interface on different devices and apps so that applicants have the same positive customer experience over and over again when accessing via all channels.

This enables meinestadt.de to offer an innovative mobile application platform.

With Drop-a-Job the employees of meinestadt.de create questionnaires on behalf of the customers. These questionnaires are played out to potential applicants via applyNOW and query their skills and knowledge. Drop-a-Job also features an intuitive UI.

JobMail enables candidates looking for a job to subscribe to individual search queries.

Collaboration on JUICE

The ESA mission JUICE (JUpiter ICy moon Explorer) is scheduled to start in 2022 to investigate important questions concerning the nature and formation of the Jupiter system. The special focus of this mission is on the water, methane and carbon oxide resources of the Jupiter moons Ganymede, Callisto and Europa. Aided by the Max Planck Institute for Solar System Research two essential measuring instruments, the submillimeter-wave instrument (SWI) and the particle environment package (PEP) are being developed to examine chemical compounds. We work together with the Max Planck Society on the SWI, to integrate it with the satellite bus.

Collaboration on ConEd

ConEd (Conceptual Engineering Editor) is a new, efficient way to calculate the statics of buildings. The implementation is made in Allegro Common Lisp. The ease of handling and its efficiency are the key factors for the civil engineer. We assist Eisfeld Ingenieure AG with this project.The result of this is the software ConEd, which works the way engineers think. As a consequence, engineers not only work faster, but less error-prone, too. With ever shorter design processes this becomes increasingly important. ConEd is intuitive and easily operated without having to go through a long and time-consuming training period.


Pepa - Open Source DMS

Pepa is a document management system (DMS) and our foremost open source project. Its main purpose is archival of documents.

Upload a PDF via the browser, send it via email or print right into the system. Text will be extracted via OCR and individual pages will be rendered as images so that you can view them right in your browser when searching the archive. That way, all documents are available in digital form so that you don't need to keep as much paper anymore.

Both the Pepa server and web client are implemented in Clojure. Thus Pepa is platform independent, you can use it with any operating system of your choice.
