Stefan Hoelzl
Software Engineer at BALTECH AG
Munich, Bavaria, Germany
Summary
🎓
Top SchoolStefan Hoelzl is a pragmatic software engineer based in Munich with 8 years of experience building automation-first systems across Python, TypeScript, and cloud-native infrastructure. He designs and ships full-stack web applications and serverless deployments, but also architects robust test automation—having built an in-house E2E firmware test framework that combines randomized fuzzy testing with statistical monitoring of firmware quality. His background spans embedded firmware, distributed build/execution backends on Kubernetes, and CI/CD infrastructure, giving him a rare blend of hardware integration and large-scale DevOps experience. Stefan repeatedly turns manual testing and manufacturing workflows into reliable, automated pipelines, improving insight with BI tooling and data-driven quality metrics. Colleagues rely on him to bridge product, test, and operations concerns—plus he’s comfortable contributing across the stack from low-level firmware to Vue frontends. An underappreciated strength is his long history of teaching and tooling work, which shows in clear engineering processes and maintainable codebases.
