[ 01 ] — What I actually am

4 modes
01 / 04

AI ENGINEER

Agents that do the boring parts

I wire up AI agents, API tools, and coding assistants into real workflows — from a text-to-website builder to automations that take grunt work off my plate.

  • Agent workflows
  • API tooling
  • Prompt design
  • Automation
02 / 04

NETWORK ENGINEER

The plumbing behind the magic

60 hands-on MikroTik labs deep — routing, switching, VLANs, NAT, firewalls, hotspots. I configure it, break it, fix it, then write down exactly what happened.

  • TCP/IP
  • MikroTik
  • Routing
  • VLANs
  • Subnetting

CYBERSECURITY

Break to understand, defend to win

#1 LKS Cybersecurity champion and Cyber Jawara nominee. CTF practice, web exploit basics, Linux forensics — learning defense by understanding offense.

  • CTF
  • Web exploits
  • Forensics
  • Red team intro
  • Kali

[ 06 ] — How I got here

  1. 2024

    Started the TKJ path

    Entered SMK Dwija Bhakti 01 and began Computer & Network Engineering — first contact with routing, Linux, and the command line.

  2. 2025

    Stepped into competition

    Expanded into competitions, English presentation, and stronger networking practice — Cyber Jawara and English national nominations.

  3. 2026

    Sharper focus, real wins

    Deeper cybersecurity readiness, a #1 LKS Cybersecurity finish, #1 school ranking, and a portfolio that ships.

  4. Next

    Build useful systems

    Heading toward C1 English, more security depth, and tools that other people actually use. Learning by building, in public.
