Profile
I design and build service-oriented backend systems for the Handelsblatt and WirtschaftsWoche apps. On the side, I maintain a Nuxt-based SaaS boilerplate used by close to 1,500 customers worldwide.
Work experience
April 2024 – present
Software Architect
Handelsblatt Media Group GmbH & Co. KG, Düsseldorf
I own the design and delivery of a service-oriented backend landscape for the Handelsblatt and WirtschaftsWoche apps. Significant architectural decisions are documented and maintained as Architecture Decision Records (ADRs). Alongside that, I produce system diagrams to visualise the software architecture and align them with the teams involved in dedicated workshops. I also supported the migration to and rollout of Livingdocs, the new editorial system for the mobile apps. Working closely with the product owners, I help capture and sharpen technical requirements, and I coordinate the technical alignment with other teams across the business unit.
October 2021 – March 2024
Fullstack Developer
Handelsblatt Media Group GmbH & Co. KG, Düsseldorf
I was a key contributor to the development, maintenance and monitoring of the backend systems behind the Handelsblatt and WirtschaftsWoche apps, and occasionally supported work on the corresponding Android apps. A further focus was the architectural planning and coordination of the structural decommissioning of legacy monolithic software, along with the automated provisioning of cloud infrastructure through Infrastructure as Code.
April 2018 – September 2021
Fullstack Developer
ener|xess GmbH / green|connector GmbH, Essen
I joined ener|xess as a working student. After the merger with its sister company green|connector in September 2019, I moved into a full-time role as a fullstack developer focused on JavaScript and TypeScript. In that role I extended existing projects and contributed actively to the design and implementation of new sales platforms, mail services and sales assistants, as well as several frontends for serverless microservices.
Self-employment (part-time)
June 2024 – present
supastarter Nuxt maintainer
Timo Ischen (sole proprietorship)
I am a key contributor to the design, maintenance and ongoing development of a Nuxt-based software-as-a-service boilerplate now used by close to 1,500 customers worldwide.
September 2024 – February 2025
Backend development & systems integration (contract)
Sedecon Solutions GbR
A document management system for an enterprise client — a greenfield project on the backend that nonetheless had to fit seamlessly into an existing on-premise landscape. I designed and implemented the SharePoint integration via the Microsoft Graph API, the sync jobs that keep both sides aligned, fine-grained permission management and the CRM integration. I agreed the API specifications with the external service providers involved and surfaced the new functionality for users inside an existing frontend.
Education
February 2016 – September 2020
Business Informatics (B.Sc.)
Ruhr West University of Applied Sciences, Bottrop
Graduated with a Bachelor of Science. The working-student role at ener|xess from April 2018 overlapped with this period.
