About

For the past 10 years, I’ve been working in IT as a self-taught Frontend/Web Developer, focusing strongly on secure, performant, and accessible web applications. Now I’m pivoting my career toward Web Security—aiming to combine my deep understanding of the web ecosystem with security auditing, vulnerability testing, and OWASP-based risk analysis.

I’m expanding my skills in web application security, network fundamentals, and ethical hacking (OWASP, Burp Suite, ZAP, Linux). I’ve collaborated with clients from the USA, UK, Switzerland, Germany, Sweden, Norway, and Poland—mostly as part of Scrum teams. In many projects I took on the role of a specialist, analyzing client needs and advising on the best solutions.
