01 / Recon mindset
Offensive security fundamentals
I focus on understanding how attackers think: reconnaissance, scanning, surface mapping, and identifying where security assumptions fail before exploitation even begins.
Available for growth, labs, and real-world security practice

D0R07HY / Computer Science Student / Aspiring Penetration Tester
I am a second-year Computer Science student at Mahasarakham University building a portfolio around offensive security, hands-on lab work, and continuous cybersecurity learning. My goal is to grow from structured coursework into real penetration testing practice through labs, CTFs, reconnaissance exercises, and disciplined technical study.

What this portfolio is built to show
This version of my portfolio is designed to present not just interest, but direction. It highlights where I am now, how I practice, and what kind of cybersecurity work I am deliberately preparing for next.
02 / Practical learning
Hands-on labs over passive theory
My strongest learning happens through active practice. I regularly explore wargames, CTF-style environments, and guided cybersecurity material to turn abstract concepts into repeatable workflows.
03 / Professional growth
Early-stage, but serious about the path
I am still in the student phase, so I position myself honestly: not as a finished expert, but as someone building solid foundations with clear goals in penetration testing and red team methodology.
Journey
How I am building toward security work
My path is a mix of university study, certification milestones, and independent practice. The point is steady compounding: every lab, every challenge, and every certificate sharpens the next step.
Current foundation
Computer Science student with a cybersecurity direction
I am studying Computer Science while shaping my learning around cybersecurity topics that support offensive work: networking awareness, systems thinking, command-line confidence, and analytical problem solving.
Hands-on practice
Using labs, wargames, and tooling to build discipline
I spend time on exercises such as OverTheWire-style challenges, scanning practice with Nmap, and CTF-oriented problem solving. These activities help me connect theory with methodical execution.
Next objective
Prepare for internships, deeper labs, and advanced study
The near-term goal is to keep strengthening portfolio evidence through learning artifacts, technical practice, and better documentation. The long-term goal is graduate study in Germany and a stronger path into offensive security roles.
Toolkit
Core topics and tools I am actively developing
This is the stack I currently associate most with my learning path. It is intentionally honest: these are areas I am practicing, not empty buzzwords added just to fill space.

GitHub for Developer
Supports cleaner version-control habits, collaboration readiness, and a more disciplined project workflow.
Open verificationWhat I bring now
Curiosity with structure
- I learn best by testing concepts in practice rather than stopping at theory.
- I am building a portfolio that reflects direction, not exaggeration.
- I care about understanding why systems work, fail, and become vulnerable.
What I am building next
Clearer technical proof
- More documented lab work and challenge-based write-ups.
- Deeper web and network security practice through repeatable exercises.
- A stronger body of work for internships, collaborations, and advanced study.
Contact
Open to learning opportunities and serious collaboration
If you are looking for a student who is genuinely committed to cybersecurity growth, I would be glad to connect. I am especially interested in opportunities that strengthen offensive security fundamentals, practical lab experience, and disciplined technical development.
Best fit: internships, student collaborations, CTF teams, and communities that value consistent hands-on improvement.
