About

I'm an Informatics student specializing in Software Engineering and Fullstack Development, with a secondary focus on Cybersecurity. My work centers on building practical, well-structured web applications while deepening my understanding of data structures, algorithms, backend engineering, and system design.

Alongside development, I study security from both sides of the equation — how systems are attacked, and how they're detected, defended, and hardened — with particular interest in network security, security testing, and system hardening.

Currently exploring: Go, backend engineering at scale, and offensive/defensive security fundamentals.


Tech Stack

Languages C PHP JavaScript TypeScript Python Go

Frontend React Tailwind CSS Vite

Backend Laravel Node.js

Database MySQL PostgreSQL

Tools & Infrastructure Git Docker Linux GitHub


Cybersecurity Focus

Cybersecurity is my secondary discipline, approached through the lens of both offense and defense:

Area Focus
Network Security Traffic analysis, segmentation, hardening
Application Security OWASP Top 10, secure coding practices
Vulnerability Assessment Identifying and prioritizing weaknesses
Security Testing Manual and tool-assisted testing
Offensive Security Attack simulation fundamentals
Defensive Security Detection, monitoring, response
Purple Team Operations Bridging attack and defense workflows
System Hardening Reducing attack surface on Linux systems

Guiding question: How are systems attacked — and how are they detected, defended, and hardened in response?
