Hi there 👋 I'm Yasin

Software Engineering student at Konya Technical University, building a foundation in software and moving toward offensive security.

I come from the engineering side — I like understanding how things work underneath and building real tools — and I'm now channeling that into security: web application pentesting, vulnerability research, and the fundamentals behind them.

⍶ What I'm focused on

  • Building apps in Java and JavaScript, and writing tools in C and Python
  • Going deep into offensive security — web app pentesting & vulnerability research
  • Working through HTB Academy job-role paths: Penetration Tester and AI Red Teamer
  • Sharpening fundamentals: algorithms, data structures, Linux, and networking

β Tech & Tools

Languages — · Java · JavaScript · C · Python Security & Environment — Burp Suite · Linux / Kali · HTB · PortSwigger Web Security Academy Dev — Git · CLI · VS Code

𝛉 Featured Projects

  • undodecider — A secure password generator written in C, built on cryptographically secure randomness. A small project with a security-first mindset — getting the randomness right instead of just "random enough."
  • save-e — A utility that monitors Steam downloads and automatically shuts down the system once they finish. Practical automation that solves a real annoyance.
  • meridien — Plugin-based security scanning and reporting platform that orchestrates recon, DAST and SAST tools into a unified findings schema.
