SOC Analyst / Cybersecurity Analyst

Efrain Reyes

I help detect and investigate suspicious activity by analyzing logs, alerts, and network traffic. I’m actively building a portfolio based on real security scenarios and documenting my work on GitHub. I hold CompTIA Security+ and I’m currently pursuing a degree in Cybersecurity.
