Summary

Matthias Spiller is a senior software developer with over 19 years of experience in developing, maintaining and modernizing technical software systems – mainly in embedded, automotive and industrial environments. He helps companies get unstable or outdated systems back under control: through thorough debugging, targeted performance optimization, legacy code modernization and setting up test and CI/CD infrastructures.

His technical strength lies in analyzing complex C++, C# and Python codebases, often on Linux or Windows with CAN, LIN, Ethernet or other bus systems. In addition to implementing new features, he also takes on cross-cutting tasks: architecture consulting, interface design, DSL development (Xtext) or refactoring to reduce technical debt.

Typical fields of application are embedded devices, controllers, diagnostic tools, data pipelines or simulation environments – even where documentation is missing or systems have passed through many hands. He operates through his GmbH, prefers to work remotely and is available on-site for project phases.
