Notes from 13+ years in system administration, cloud infrastructure, and network engineering — AWS, Linux, Proxmox, Datadog, and security, written from real-world experience.
This blog covers the real-world challenges and solutions I encounter as a Senior System & Network Administrator based in Bengaluru, India. Articles focus on practical implementation — not theoretical overviews — drawing from production environments across healthcare IT, digital currency infrastructure, and enterprise networking.
Topics include: Proxmox VE cluster design and virtualisation at scale, AWS infrastructure cost optimisation and architecture best practices, Linux hardening using RHCE-grade techniques (SELinux, firewalld, auditd), Datadog monitoring with SNMP, NetFlow and custom dashboards, and enterprise network security using Sophos XGS firewalls, Cisco VLANs, and IPSec VPN.
Each article is written from direct, hands-on experience — the kind of knowledge that comes from troubleshooting production systems at 2 AM, not from reading vendor documentation.
