# whoami
Cybersecurity specialist and fullstack developer with 6+ years of experience spanning CERT operations, malware analysis, application security, and enterprise software development.
I started my journey at ComCERT SA where I handled Tier 1/2 incident response, reverse-engineered malware families like DanaBot and TrickBot, and automated deepweb threat intelligence gathering.
Today I help build aipol.com.pl as lead tech person β delivering custom software, AI automation, and security services β while building hackersim.io after hours and working on skanujzdrowie.pl with Novazym laboratory.
# philosophy
βΈSecurity through deep understanding, not checkbox compliance
βΈBuild tools that automate the boring parts of threat hunting
βΈTeach what you know β knowledge shared is knowledge multiplied
βΈLong-term commitment over short-term gains
