Rockstar🎓
Top SchoolLajos Papp is a seasoned DevOps engineer and technical trainer based in Budapest with 15 years of experience building and operationalizing cloud-native platforms. He co-founded SequenceIQ and later contributed to Hortonworks’ Cloudbreak project, working across backend, frontend, and deployment pipelines for large-scale data platforms. As a self-employed Technical Trainer since 2018, he translates deep hands-on experience—containerization, Docker-based Ambari automation, CI/CD and platform hardening—into practical DevOps courses for enterprises. His background as a long-tenured software architect at EPAM and advisor roles brings a pragmatic blend of systems design and developer-focused tooling. Notably, his open-source commits reflect an appetite for solving both user-facing bugs and the gritty DevOps plumbing that keeps platforms reliable.
