Senior🎓
Top SchoolPetri Lammi is a seasoned cloud and security engineer with 11+ years of hands-on experience designing and automating hybrid cloud services using Ansible, Puppet, Terraform and Kubernetes/OpenShift. As a partner at Puppeteers Oy and former Security Engineer at OpenVPN, he blends deep Linux expertise and identity/SSO mastery with pragmatic security controls, penetration testing and observability stacks like Prometheus/Grafana and Wazuh. He routinely bridges declarative and imperative approaches, shipping infrastructure-as-code while maintaining compliance-driven XDR/SIEM and VPN/identity deployments across AWS, Azure and private clouds. Known for tinkering with SDRs and hardware hacking tools in his consulting work, he brings a researcher’s curiosity to production-grade automation and lifecycle management. Outside work he follows space exploration, plays guitar and keeps fit with weight training—habits that mirror his disciplined, detail-oriented engineering style.
