Founder & Lead Editor

I launched TodayNotes after noticing a significant gap in the community: there were plenty of surface-level tutorials, but very few deep-dive articles that addressed the nuances of modern administration.

With a career built in high-stakes environments—including managing a 230-rack data center—I wanted to create a space where I could share the expertise I've gathered over the years.

  • Experience: Lead Database Admin in large-scale Data Center operations.

  • Expertise: Linux Systems, DNS Management, and Database Administration.

  • Education: 

    • M.Sc. in Information Technology

    • B.E. in Electronics and Telecommunication

    • MCSA: Microsoft SQL Server 2016

  2. Current Content: Information in IT expires quickly. We regularly audit our archives to ensure all commands and data reflect the latest standards of 2026.
