As a freelance security auditor, I’ve completed two paid software security audits and found a critical-severity vulnerability in one. I’ve reported vulnerabilities to companies three times, including one finding confirmed in the international Code4rena security competition.
I write reports with risk assessments, reproduction steps and remediation guidance. I also built a tool that combines several code scanners into one pipeline, first in Python and later rewritten in Bash.
I currently run a computer repair and IT services business in Kaunas. One laptop cleaning and maintenance job lowered the CPU temperature under heavy load by 30 °C; I also help clients with computer maintenance, security checks and Wi-Fi settings.
I learned cybersecurity hands-on through TryHackMe, CTF challenges and my home lab, working with Kali Linux, nmap, Burp Suite, Metasploit and Wireshark. I also created Never-Poor-Again, a deliberately vulnerable system with automated attack tests, published as a public CTF challenge.
