0x04 / journey

1. 2024

   Early Interest in Technology

   Junior High School

   I started my journey with a strong curiosity about computers and how digital systems work. This curiosity led me to explore programming and technology more deeply.

2. 2025

   Discovering Cybersecurity & CTF

   Vocational High School

   I found cybersecurity through Capture The Flag (CTF) challenges. I started with digital forensics, then moved into binary exploitation (pwn), which is now most of my writeups, and I'm expanding into web exploitation.

3. 2025 - Now

   Linux & Infrastructure

   Homelab

   I run Linux (CachyOS) as my daily driver and self-host my own services on a homelab: Docker and Coolify behind a Cloudflare Tunnel, with a DevSecOps dashboard monitoring the servers and containers.

4. 2025 - Now

   Building for the Web

   Personal & School Projects

   I build full-stack web apps with Next.js, Prisma and PostgreSQL, from a class hub and a school e-voting system to this portfolio, and deploy them on my own infrastructure.

5. Now - Future

   Future Goals

   Vocational High School

   My goal is to grow as a cybersecurity professional specializing in binary and web exploitation, with Linux administration and web development as my foundation, while I keep learning, building, and competing in CTFs.
