Cloud-Native QA Automation and CI/CD Integration

At SIXT, I architected a cloud-native test automation ecosystem that unified mobile, API, and performance testing within CI/CD.
He developed an Appium-based mobile automation suite integrated with Jenkins pipelines for parallel execution on Android and iOS, significantly reducing feedback cycles.

Sandal built a Spring Boot microservice that interfaced with Kubernetes to dynamically spin up and destroy test environments on demand — integrating Jacoco for real-time coverage analysis.

Performance and security validation were automated using Gatling, Lighthouse, and OWASP ZAP, embedding them directly into deployment pipelines to enforce quality gates.

Key Achievements:
Cut regression execution time by 50% through parallel and containerized testing.
Enforced DevSecOps practices by integrating security scans into build pipelines.
Created a coverage-driven release readiness dashboard for continuous quality visibility.
