The world is becoming more and more digital and thus more complex: Until 2020, more than 4 billions of people will be connected to the internet. The future of many companies therefore lies in digitalization. But for many it is as mysterious as the universe.
With over 20 years of experience in web development, more than 10 years of experience in mobile app development and more than 5 years of consulting experience in the financial sector, we provide the necessary expertise and support.
The process of our collaboration is as follows:
Together with the department, we work out and finalize the project idea. In the next step, the concept is written down in the form of a so-called epic/user story. This document contains all requirements for the final module.
In the requirements management, the epic/user story is evaluated in terms of content and structure by various development departments. It has to be estimated which systems have to be used and when and where systems have to be adjusted and, if necessary, a software has to be rewritten. If the epic/user story is accepted, the department head will receive a cost-indication estimate as well as information on personnel resources.
Our development department works out the module according to the epic/user story. The sprint cycles are based on your preferences. Depending on the company structure, the sprint cycles usually last between two and four weeks. The developed module then goes into the system test.
The testers approve the module and test it for bugs and defects. If the testers have findings, the module goes back to development to get fixed. Once the tests run without errors, the module will be deployed.
In the final acceptance all surrounding systems of the main system are tested again. If they work well, the product can be made available.
Nikolaos Papagiannis and Alexander Bauer get to know each other at school in Bielefeld. After that, both studied business informatics and started working for the same company.
The introduction of the first iPhone also marks the beginning of the era of mobile app development. Both founders have been involved in app development since then and have more than 20 years of web development experience.
After their paths had separated for a short time, they realized in 2009 that they work best together as a team.
Niko and Alex started their own business and work together since then.
Alex and Niko found Excelsior out of frustration with large companies that focus rather on the margin than on professional and qualitative implementation.
Our employees, who all have a background in IT and are specialists in their fields, share the vision of always supporting customers with honest consulting and sustainable software solutions.
