Rockstar🎓
Top SchoolSamuli Seppänen is a seasoned Senior Analyst and DevOps generalist with 15+ years building and automating infrastructure across cloud and on-prem environments, from Terraform and Puppet to CI/CD and custom Windows installers. He has deep hands-on experience in virtualization, VPNs, identity management and monitoring, and has contributed build, test and installer improvements to prominent open-source projects like OpenVPN. As CEO of Puppeteers Oy and long-time OpenVPN community engineer he blends product delivery, mentorship and practical security-minded automation for European clients. Samuli pairs a methodical, detail-oriented engineering approach with a curiosity that spans experimental archaeology, carpentry and ancient languages—skills that reflect his patience for complex reconstruction and systems thinking. He’s comfortable operating at both strategic risk-assessment levels (geopolitical software risk) and in low-level build/release scripting, often improving installer and signing workflows for Windows releases. Based in Turku, Finland, he champions openness and reproducible infrastructure while quietly enjoying reconstructing ancient Roman engineering.
