Robert Dzaka

Software EngineerSecurity AnalystIT Support Specialist

Passionate technologist with a unique multifaceted journey spanning software development, systems administration, and cybersecurity. I don't just write code—I architect secure solutions, troubleshoot complex systems, and think like both a developer and a potential attacker. Building technology that users can trust, one secure line of code at a time.
