Audit of the existing architecture of the energy storage management system. Documentation of the architecture and and setting up of the change management process with ADRs (Architecture Decision Records). The goal was to make the architecture more transparent and to enable the development teams to make changes more efficiently. And semi-automated approach was taken by using Structurizr as a tool to visualize the architecture and to generate documentation. The deployment artefacts were dockerized and the deployment process of the documentation was automated. Stakeholder communication with VP of Cloud Services and internal IT Architect.

Development of a web-based management frontend for support agents of the energy storage management system. The goal was to provide the support agents with a tool that enables them to manage the customer's charging infrastructure in a more efficient way. The challenge was to prepare the components in a way so they can be re-used later in different scenarios accross the company e.g. in the existing portal. The generic approach was achieved by decoulping core functionality in separate package and importing them into the main app. The frontend was developed with React and Typescript. The development was done in a team of 4 developers and 2 QA agents. The requirements were collected in close cooperation with the support agents. The development process was agile with 3-week sprints. The UX was visualized in Figma. The API was designed with OpenAPI. The backlog was managed Azure DevOps and later in JIRA. The project included stakeholder communication with the VP of Cloud Services and the internal Product Owners.

After 12 years of custom software development for corporations and medium-sized businesses, we decided to channel our expertise into a product. Our product, CaseOS, is a digital toolkit that allows applications, frontends, and apps to be dynamically developed with a WYSIWYG editor. However, the user is not limited in terms of customization. On the contrary. The system is designed from the ground up for whitelabeling and expansion. The user's own CI/CD can be easily implemented, and individual extensions can be developed by themselves. Both in the frontend and in the backend, there are no limits. Neither in the choice of technology nor in the platform. Since the system is completely based on web technologies, all channels can be served from it: Web, PWA, App, Desktop, and theoretically even embedded systems.

As a technical Product Manager and Team Lead of 5 developers and a UX, I had the E2E responsibility for the development of RFID card management & charging process authorization (OCPP), extended role & rights system, roaming and compensation tariff management service, and dashboard/reporting functions. The starting point was the analysis/migration of the charging infrastructure of one of the largest premium automotive brands from one CSMS backend to another. I derived feature deltas, planned features, developed a roadmap, and coordinated with other stakeholders. In addition, as part of the planning of the implementation, central architectural adjustments were coordinated and implemented with up to 7 teams. Regular, company-wide season plannings were carried out and topics were planned based on OKRs (Objectives and Key Results). Agile process with UX prototyping and rolling releases, 5 new Typescript/NestJS microservices developed. Compilation of the team including writing the tenders, interviews, participant selection, and onboarding.

Broad-based consulting services in an Angular/Microservice development project with about 40 employees and Board-of-Management attention. As Frontend Lead, I coordinated the requirements with stakeholders, backend leads, and the frontend team. I empowered junior developers in the use of Angular 11+. I introduced newcomers to the codebase. I implemented and further developed the design system and essential central components. My role also included enhancing cross-team communication. For this purpose, I scheduled weekly developer/PO/Lead meetings (Dev-Insights) to address topics. It was my responsibility to maintain UI/UX consistency both during development and in the conceptual phase of new features. Wireframes and mockups were realized in Figma for a better conveyance of the later look & feel of the application. I wrote automated component unit tests. The project was conducted with SAFe.

Based on the Low-Code platform CaseOS, a dashboard was developed to visualize the daily bale production numbers. A monthly and yearly view also allows the viewer to carry out controlling or planning. They can change decisive KPIs (bales/day, average working hours/hour, or working days/month) in real-time and view the effects. The data is pushed in real-time from the press to the browser without the user's active intervention and is retrieved from the Siemens S7 via OPC UA. The users were trained after commissioning.

A configurable OPC-UA adapter was written that reads or subscribes to data from OPC-UA sources, interprets the data, checks it, and if necessary, transforms it. The data is sent to the target application via REST/WebSocket. In the event of a failure of the target system, the data is buffered in the adapter and sent again at the next start.

To enhance customer loyalty and transition the existing paper building manual, an iOS and Android app was developed. In addition to the reprocessed content of the existing household manual, it offers the functionality of alerting for recurring maintenance. This includes, for example, green roofing, house water filters, ventilation systems, and others. The end customer can independently change and add new content through the No-Code WYSIWYG editor. The app works offline and synchronizes in real-time with the server to load new content and downloads (PDF) as soon as it is online. Files and content are stored on the local device filesystem.
