Projekthistorie

02/2023 - bis jetzt
Education Process and Organization System (IU Group, Development Architect)
IU Group N.V., München (Sonstiges, 250-500 Mitarbeiter)
Development of a management system for one of the biggest distance universities in the market. During Covid the customer had outgrown its legacy system. It needed to be replaced gradually with a more scalable and suited solution while keeping the legacy system alive and functional.

The new system was designed along domain-driven strategic design boundaries and set up as a microservice architecture mainly consisting of NestJS services communicating via Kafka.

A set of microfrontends were tailored to bring the new experience to our customers.

As a Development Architect I worked on different teams, domains and infrastructure topics to help bring the project to life.

After less than six months into the challenge Wattbewerb already reaches 116 communities with approx. 14 Mio. residents.

The “Spielplattform” displays the current ranking of all competing communities. It is 100% based on data from the Marktstammdatenregister of the Bundesnetzagentur.

As a consultant I advise developers at BFITS on development topics around SAPUI5 and other web technologies. Architecture and infrastructure consulting is also part of my mandate. What started out as SAPUI5 Consulting evolved into broader technology consulting including technologies as Ionic, React, Web Components or turtleDB.

Several projects went live with great success and the most positive user feedback.

Due to the evolving complexity of the SAPUI5 ecosystem at SEW a new and more supportive infrastructure was required. State-of-the-art technology was picked to solve problems with UI performance, code collaboration, dependency management, deployment hassle and many more. 

From now on Azure DevOps Server acts as code repository and continuous deployment server. It performs all kinds of standard JS and SAPUI5 tasks (ESLint, uglify, sourcemaps, preload-files etc.), executes unit tests and provides code coverage reports as well as JSDoc. It automatically deploys releases to a private npm repository (sinopia) and into SAP infrastructure namely SAP MII (DTR) and SAP Gateway (BSP).

Nestlé CIO Challenge – Mobile Workflow Inbox (2012, 4 months)
Expert Developer
SAP SE, Walldorf / Vevey, Switzerland

In this amazing project, SAP had to proof to one of its biggest customers that they can deliver state-of-the-art mobile experiences in 30, 60, resp. 90 days. Seven responsive apps were built with Sencha Touch surrounded with a simple iOS container providing native features. They went online at Nestlé with great success laying the ground for subsequent SAP mobile developments namely SAP Fiori.

As part of the development team I introduced Continuous Integration to streamline the release and deployment process. I also supported on-site in rolling out the solution including the implementation and introduction of a similar development landscape.
