About João Silva

I focus on cyber defense and incident response, but I’m also drawn to understanding the attacker’s mindset. By exploring both sides and earning certifications along the way, I’m able to build smarter and stronger defenses. I'm always curious, always learning, and eager to team up with others who share my passion.I'm also a hands-on learner who loves diving into personal projects to really understand how things work. Whether I’m testing new security tools, refining system configurations, creating blog posts or setting up environments to explore evolving threats, I learn best by doing. These projects keep me growing, keep me engaged, and ultimately help me become a better professional.TryHackMe (TOP50🇵🇹): CybB0rgGithub: CybB0rgCertifications:• CompTIA Security+ ce Certification (Sec+)• ISC² Certified in Cybersecurity (CC)• Google Cybersecurity Specialization (GCC)
