KJComputer science grad turned security nerd.
After studying computer science at EAAA in Aarhus, spending my time somewhere between building things, learning objects, breaking stuff, the curiosity for cybersecurity became too big.
So I found a passion in cybersecurity and now, i’m giving my everything to try and learn all about it.
The balance between offense and defense and understanding the critical part of protecting what can be exploited.
📍 Aarhus, DenmarkA personal sneaker management app designed to track the buying and selling of my collection. Beyond simple inventory, it features a dedicated financial dashboard that calculates sales data to simplify VAT and tax reporting.
A lightweight browser extension that detects phishing sites in real time. It analyzes URLs for suspicious patterns and warns you before you land on something malicious.
A little homelab where i simulate, test, and validate various cybersecurity tools, network configurations, and software solutions in a controlled and isolated environment.
Everything from running different linux vms (kali, ubuntu etc.), metasploit, elastic SIEM and so on.
I also hosted my personal database and have tools like Pi-hole and Unbound installed for increased privacy and use Tailscale to access it all remotely.
A small GitHub Actions tool that turns Hacker News into a compact daily reads.
Fetches the top front-page stories from the HN Algolia API, and uses Mistral chat API to generate highlights and summaries.
