01 — About

Engineering mindset,
automation-first.

I'm an IT student in Sydney focused on becoming a DevOps engineer with deep, documented fundamentals. I learn publicly — every command, every script, every concept gets documented.

My approach: understand systems deeply, automate everything repeatable, and solve problems with clean logic. Competitive programming sharpens this discipline further.

  • 90 Days of DevOps — publicly documented journey
  • Linux internals & process management
  • Shell scripting & CLI automation
  • Git & GitHub workflows (reset, rebase, PR, CLI)
  • Networking fundamentals (DNS, IP, CIDR, ports)
  • CI/CD concepts with GitHub Actions

Git & Version Control
Advanced Git workflows — rebase, reset, PR management, GitHub CLI. Clean commit history is discipline, not an afterthought.

Networking
Fundamentals that matter: DNS, IP addressing, CIDR notation, ports, protocols. Understanding traffic is understanding infrastructure.

Algorithmic thinking
sharpens engineering.

I actively solve problems on Codeforces in the Div2 A/B/C range. This directly improves how I write automation scripts, design system logic, and debug under pressure.

Strong algorithmic discipline means cleaner automation, better edge case handling, and faster debugging in production systems.
