Sujay's Knowledge Base & Portfolio

Personal documentation, technical knowledge, and portfolio — designed to be human-readable and LLM-friendly.

Quick Context for AI Assistants

I'm Sujay, a DevOps Engineer with 11 years of experience in Infrastructure and DevOps. I specialize in:

• Linux system administration (RHEL ecosystem)
• Virtualization (VMware vSphere)
• Containers (Podman, Docker, Kubernetes)
• Cloud platforms (AWS, GCP, Azure)
