What I'm looking for

I’m seeking a penetration testing or SOC internship or junior position.

At CEFET-MG, I’m researching how large language models can analyze ROP gadget semantics and support x86 Return-Oriented Programming chain synthesis. I’m building an experimental pipeline to compare LLM-assisted analysis with heuristic, SAT/SMT-based, and naive LLM approaches.

At Virtua MX, I performed penetration tests across web applications, infrastructure, and cloud deployments, identifying vulnerabilities and developing proofs of concept to validate findings. I also used security tools and scripts for analysis and remediation support, audited PKI and X.509 configurations, and integrated security testing into CI/CD workflows.

At Investment in Motion, I was the main backend developer for Padel Band México, an e-commerce platform, and built several frontend views. I integrated Mercado Pago Checkout Pro and managed deployment and hosting through a partial production rollout.
