01 / PROFILE
Background & Focus
I'm Md. Firuz, a network & security engineer passionate about high-performance ISP infrastructure and intelligent automation. I manage routing, firewall policies, and VPN architectures while writing Python scripts that automate bandwidth shaping, PPPoE provisioning, and real-time anomaly detection.
My security workflow involves deep packet analysis (Wireshark, tcpdump) and reverse-engineering mobile/ web APIs using Burp Suite and custom mitmproxy pipelines — turning traffic insights into robust automation tools.
I'm currently pursuing CCNA & CompTIA Network+ and actively building open-source network monitoring solutions.
