Structuring systems so teams can add functionality more safely and operate with less uncertainty
Matthias Schobner
Backend Developer
I work on backend systems that need to stay changeable as they grow more complex over time. My focus spans stabilizing existing applications, evolving them in a controlled way, and building new systems, backend structures, and APIs from scratch.
Backend work that keeps systems changeable as they grow.
I work on backend systems so they can be evolved in a structured, controlled, and reliable way. That includes refactoring and evolving existing applications, extending them with new functionality, and building new backend structures, APIs, and integration flows from scratch.
- Clarity over cleverness
- Structure over chaos
- Simplicity over unnecessary complexity
What I usually work on.
- Evolve applications through new backend features and continuous technical improvements
- Design integrations, external interfaces, and reliable data flows between systems
- Stabilize existing systems through refactoring, clearer structures, and reduced complexity
- Create Docker-based development and delivery environments that support controlled, reproducible work
- Build new systems, backend structures, and APIs from scratch
Where I bring the most value in backend work.
Integrating external systems reliably so imports, ordering flows, and synchronization processes remain predictable
Understanding complex systems quickly and identifying the parts that matter most
Building developer-friendly environments so project setup and daily work stay reproducible and controlled
Designing clear boundaries and responsibilities so backend structures stay maintainable as they grow
What I do not do.
- No quick hacks that turn into larger problems later
- No unstructured feature development without clear boundaries and responsibilities
- No short-term solutions that ignore long-term maintainability
Selected projects.
Examples from product and integration-heavy environments where stability, ongoing evolution, and backend design all mattered at the same time.
