Nikolina Karamarko focused on modernizing build and deployment workflows across the wireapp/wire-desktop and wireapp/wire-webapp repositories. She migrated artifact storage from App Center to AWS S3, implementing automated S3 uploads and pre-signed URL generation using Groovy and Jenkins scripting, which improved scalability and reliability for Windows, macOS, and Linux builds. Additionally, she streamlined release management by creating draft GitHub releases and aligning macOS artifact handling with the new pipeline. In wireapp/wire-webapp, she integrated the GitHub Deployments API into the CI/CD workflow using TypeScript and YAML, enabling environment-based deployment tracking and enhancing traceability with minimal configuration changes.
