Architecture Review, Documentation and Change Management Process

Premium Manufacturer of Energy Storage Systems

Audit of the existing architecture of the energy storage management system. Documented the architecture and set up the change management process using ADRs (Architecture Decision Records). The goal was to make the architecture more transparent and enable development teams to implement changes more efficiently. We took a semi-automated approach by using Structurizr for architecture visualization and documentation. Deployment artifacts were dockerized and the documentation deployment process was automated. Stakeholder communication with the VP of Cloud Services and the in-house IT architect.

Developed OCPP Management Frontend for Support Staff

Premium Manufacturer of Energy Storage Systems

Built a web-based management frontend for support agents of the energy storage management system. The goal was to give support staff a tool to manage the customer’s charging infrastructure more efficiently. The challenge was to prepare components for reuse in various company scenarios, like the existing portal. We achieved a generic approach by splitting core functions into separate packages and importing them into the main app. The frontend was built with React and TypeScript. The team included 4 developers and 2 QA agents. Requirements were gathered closely with support staff. We followed a 3-week agile sprint cycle. UX was designed in Figma. The API was built with OpenAPI. The backlog moved from Azure DevOps to Jira. Stakeholder communication included the VP of Cloud Services and internal product owners.

Technical Product Manager and Team Lead

E-Mobility Charging Solution Provider

As technical product manager and team lead for 5 developers plus a UX resource, I owned the E2E development of RFID card management & charging session authorization (OCPP), advanced roles & permissions system, roaming and compensation rate management service, and dashboard/reporting features. We began by analyzing and migrating one of the largest premium automotive brands’ charging infrastructure from one OCPP CSMS backend to another. I derived feature deltas, planned features, developed a roadmap, and aligned with stakeholders. We coordinated major architecture changes with up to 7 teams and enforced them. We held regular company-wide season planning and used OKRs (Objectives and Key Results) to plan themes. We ran agile processes with UX prototyping and rolling releases, built 5 new TypeScript/NestJS microservices, and handled team recruiting, interviews, selection, and onboarding.

Developed Production Dashboard for Balers with OPC UA (IIoT)

Remondis Süd GmbH

Using the low-code platform CaseOS, I built a dashboard to visualize daily bale production numbers. Monthly and yearly views allow for controlling and planning. Users can adjust key KPIs (bales/day, avg. hours/day, workdays/month) in real time and see the impact. Data is pushed from the press to the browser in real time, and retrieved from Siemens S7 via OPC UA. Users were trained after deployment.

Developed Home Manual Mobile App for iOS and Android with Maintenance Notifications

Auftakt Medien e.K.

To boost customer retention and convert the paper home manual, we built an iOS and Android app. In addition to the manual’s existing content, it alerts users for recurring maintenance—like green roofs, water filters, ventilation systems, and more. End users can edit and add content via a no-code WYSIWYG editor. The app works offline and syncs in real time when back online, fetching new content and PDF downloads. Files and content are stored in the local device filesystem.

Provided broad consulting in an Angular/Microservice project with ~40 people and Board attention. As Frontend Lead, I aligned requirements with stakeholders, backend leads, and the frontend team.

I increased cross-team communication with weekly Dev-Insights meetings for devs, POs, and leads. I kept UI/UX consistent in development and concept phases. I created wireframes and mockups in Figma to convey the look & feel. I wrote automated unit tests for components. The project followed SAFe.
