The following chapters present my work profile to date using project extracts as examples. The presentation is in tabular form and includes my role in the respective projects, including a description of the projects, the technologies and the tools used.

Azure cloud consulting and software craftsmanship coaching for one of the world's biggest Microsoft Azure clients.

As the central Azure cloud solutions team of an international corporation with companies in 20 countries (energy sector), we design and develop the central cloud platform for the entire group, with hundreds of subscriptions and tens of thousands of Azure resources.

In doing so, we follow the «Azure Well-Architected Framework» and the «Microsoft Cloud Adoption Framework for Azure».

Besides the technical implementation, we focus on the organisational aspects of cloud adoption, such as governance, security, and compliance.

Our team works closely with our company's solution architects, the IPD team (internal developer platform) and the lift and shift team to help them implement state-of-the-art solutions and ensure a smooth transition of the on-premises services to the Azure cloud.

In addition to my work in that cloud team, I support our stakeholders in solving more complex problems and provide training to employees, mainly on Azure cloud technologies and in code quality, best practice patterns, domain-driven design (DDD) and test-driven development (TDD).

Planning, implementation and operation of a data aggregation & curation application using Microsoft Azure Cloud Computing Services

This project was about planning and implementing a platform for the central distribution of tickets of Swiss attraction providers via a common it-platform. In addition to offering tickets, we implemented features such as weather information, opening hours, ride times, and billing.

In this startup project, I had a multifunctional role. Initially, I was mainly involved in consulting and training to then subsequently support the setup of an Azure cloud environment and the development of the overall solution (hands-on).

In the beginning, I provided training on process models from project organization, such as SCRUM and Kanban. Then, in joint workshops, we evaluated which software best met our requirements. We then set up this software together and integrated its use into our daily processes.

After introducing essential tools such as Atlassian Jira, Confluence, Mural and Zoom, we moved towards more development-related topics.

In the second phase, we continued to build understanding and technical foundations for agile software development in workshops. Topics included continuous integration and deployment, the test pyramid, and code quality topics such as SOLID, TDD, mob and pair programming, and KISS.

In the third phase, we jointly designed and implemented a minimum marketable product (MMP). We built the development and integration environments, configured and provisioned the Azure cloud resources and performed the software development. In the grid below, you will find information on the technologies used.

Planning and implementation of this Curriculum Vitae / Résumé website.

CSS Insurance is not just a health insurance company but an insurance company for every situation in life. When it comes to health, around 1.7 million people place their trust in CSS. Its wide range of products includes health, accident and property insurance.

From 2018 to 2020, I supported CSS Insurance in various areas. I promoted the further development of employees in my stream towards even more excellence and know-how by planning and conducting training and workshops on excellence and innovation topics.

I also supported and actively participated in introducing mob and pair programmings, mainly on software craftsmanship and software excellence.

Furthermore, I supported the client in the development areas of front-end and back-end development and DevOps to initiate the transition into the world of cloud computing.

I helped my SCRUM teams analyse concrete problems, find solutions and implement them while adhering to best practices, and provided advice to the teams and lead architects of my stream.

From September 2015 to December 2017, I was involved in various projects at Swiss Accident Insurance Fund (Suva).

The Swiss Accident Insurance Suva is an essential part of the Swiss social security system. As an independent company under public law, Suva insures people at work and in their leisure time. Its prevention programmes in occupational and leisure safety prevent accidents and occupational illnesses, promote a safety culture in companies, raise awareness of hazards, and motivate people to take personal responsibility.

In the following chapters, I will break down the projects I was able to accompany at Suva.

In the RiskPricing programme, the processes for premium assessment and the systems for setting premium rates were redeveloped, taking into account the industry, risk community, bonus-malus and experience rating, and new large claims and reinsurance solutions were also implemented.

A solution was created for analysing the current risk situation and the financial situation, taking into account information from the risk information system and the adcubum SYRIUS insurance software, based on which the premium situation can be assessed and the reduction of compensation reserves calculated.

With the inclusion of the bonus-malus models and the experience rating, simulations can be carried out to set the premium rates in occupational accident and non-occupational accident insurance lines. In addition, the calculation and creation of the basic sheets and the generation of the raw data for digital printing in the context of customer communication take place in the newly created system.

In the iComm Konnex programme, various projects were implemented using the newly developed suva-internal framework RESTretto.

Support in the run-up to the production roll-out of an IT system for a leading global provider of solutions for access control and locking systems in the security industry, which gradually replaced and consolidated the core systems of the country subsidiaries.

From October 2011 to August 2014, I worked on various projects for Volkswagen AG (including Audi). I will discuss the projects in detail in the following chapters.

Architecture and lead development of an application framework for the client platform based on Java and JavaFX

Architecture and implementation of a library as well as the client platform (fat client) for the start-up planning of the production of new vehicle models for a large German car manufacturer. Development of the client architecture, as well as lead development client, and co-development middleware and backend.

Further development, bug fixing, refactoring and architectural realignment of a platform for planning and evaluation, as well as calculation and controlling of innovation projects in the automotive sector (primarily CO₂ and weight reduction) of a large German car manufacturer

InSecMa Solutions is a software company that deals with the creation of individual software and the planning, installation, configuration and operation of networks and Unix system infrastructures.

Its customers include public authorities, institutions and clients from industry. The company also develops and sells a Linux distribution for schools based on Debian GNU/Linux.

Development of a licence manager as a web-based Java EE application with an integrated SOAP interface, which enables the administration of software and customers with regard to the management of software licences. It is a classic administration application that relies primarily on input masks. The product is currently used to administer about 150 servers at 120 locations with about 60,000 connected client workstations.

As part of the Sys-C project, we developed a solution to support the interdisciplinary use of new media at schools in the city of Chemnitz. The Federal Ministry of Education and Research and the European Social Fund funded the project. The project management agency is the German Aerospace Center (DLR), more precisely the Project Management Agency New Media in Education (PT-DLR, Project Management Agency - part of the German Aerospace Center). We developed a uniform system software for school use in lessons for approximately 85 schools.

As part of a conversion of the web services of the Berlin State Library to a high availability solution, we planned, installed, configured and maintained various services.

We developed a backup strategy for the Prussian Cultural Heritage Foundation, ensuring quick recovery of the Unix and Linux server systems and various data storage devices and databases after system failures. Servers at two locations, as well as their configurations and system states, are backed up. Targeted recovery of data stocks is supported, as well as disaster recovery.
