Viviane Johns developed and refactored core API and frontend architecture for the Wahllokalsystem repository, delivering 57 features and 15 bug fixes over three months. She introduced a composable API layer using TypeScript and Axios, integrated OpenAPI-generated DTOs for type safety, and stabilized backend communication. Her work included dynamic routing, localization, and robust error handling, while improving CI/CD workflows and test reliability with Vitest and automated scripts. By restructuring code, enhancing documentation, and enforcing code quality standards, Viviane reduced onboarding time and maintenance costs, enabling faster feature delivery and more reliable integration points between frontend Vue.js components and backend services.

In 2025-01, Wahllokalsystem delivered a foundational API architecture refactor, enhanced test stability, and broad codebase hygiene improvements to enable faster feature delivery and safer backend integration. Key outcomes include: a composable API layer with async postMessage, internal message handling refinements, and UI reset extraction; OpenAPI-generated DTOs and an Axios-based API client for safer, scalable backend communication; stabilized test runs through alias resolution fixes in Vitest tsconfig and related config; expanded test coverage for messaging APIs (getMessage, postMessage, messageRead) and WLS handlers; overall code quality improvements including lint improvements, removal of generated noise, and documentation enhancements. Business value: reduced maintenance costs, improved developer velocity, and more reliable integration points with backend services.
