Whoami

I am an information security professional focused on offensive security, graduated in Cybersecurity from FIAP, and also a software development enthusiast.

I discovered my passion for information security in 2020. At 18, I left my hometown in another state to move to São Paulo, Brazil, in search of both professional and academic opportunities. I landed my first role as a mid-level pentester at ISH Tecnologia, where I stayed for two years, gaining hands-on experience in the field. Currently, I work as a cybersecurity analyst focused on pentesting at Verx Tecnologia.

My first certification was the Certified Red Team Operator (CRTO). Since then, I have continuously progressed in the offensive security domain.

At the moment, I am working toward obtaining the Certified Red Team Analyst (CRTA). As next steps, I aim to achieve certifications such as the Offensive Security Certified Professional (OSCP), Practical Network Penetration Tester (PNPT), CRTP, BSCP, SCMP|A, SCWAP, CRTE, and CMPen (Android). The order may vary, but these are my planned goals.

Today, my main objective is to build an international career and pursue opportunities outside Brazil.
