Rockstar

Hari Sekhon is a London-based DevOps Engineer with 14 years' experience blending cloud architecture, data engineering and big-data operations. He pairs ex‑Cloudera depth with hands-on DevOps: maintaining 50+ Docker images, authoring production-ready Kubernetes configs, and stewarding a widely used Nagios plugins collection that preserves compatibility across Hadoop versions. Hari focuses on pragmatic automation and CI/CD hardening—creating bootstrapping scripts and fixes for Azure DevOps, Jenkins, GitHub Actions and other pipelines to reduce build-time breakages. His open-source contributions prioritize stability and backward compatibility, often resolving subtle edge cases in legacy Hadoop and distributed systems. As a digital nomad, he brings multi-cloud operational experience and a knack for practical tooling that cuts operational toil and speeds platform adoption.
