Developed and delivered a core feature for the viasoftkorp/KorpSetupLinux repository, enabling fiscal operations through integration of a fiscal service with the API gateway. Focused on enhancing deployment flexibility, the work introduced environment-variable based configuration management, allowing safer and more adaptable deployments in Linux environments. Leveraging skills in API management, DevOps, and Docker, the implementation maintained clear traceability with a single, targeted feature commit. The approach emphasized alignment between API gateway modifications and fiscal workflow requirements, utilizing JSON and YAML for configuration. This work provided a foundation for controlled, flexible deployments and streamlined fiscal service integration within the Linux deployment pipeline.
