What I'm looking for

I’m open to international relocation to the USA, Canada, or EU, and seeking visa sponsorship. I’m open to on-site, hybrid, or remote work.

At Technometrics Limited, I lead Red Team and VAPT engagements across web apps, APIs, internal networks, and perimeter infrastructure. I’ve reported critical and high-severity vulnerabilities with prioritized remediation guidance, and mapped attack paths to MITRE ATT&CK.

I also engineered an on-premise ELK SIEM with custom dashboards and tuned detections, and built Python and Bash automation for reconnaissance and reporting. At TechForing Limited, I performed digital forensics and internal penetration testing; my projects include an OSINT news analytics platform and a modular Python-based C2 framework for ethical red-team simulation.
