Think like an attacker to defend organisations, finding weaknesses ethically and under full authorisation.
Found critical vulnerabilities in major client systems before attackers could and helped strengthen defences.
Test web applications, networks and infrastructure, finding the vulnerabilities a real attacker would exploit.
Exploit and prove vulnerabilities safely, showing clients the real impact without causing actual harm.
Assess and prioritise risk, so clients fix what genuinely matters most rather than chasing every minor issue.
Write clear remediation reports and advise clients, turning findings into fixes that actually close the gaps.

Found critical vulnerabilities in major client systems before attackers could and helped strengthen their defences. Conducts authorised penetration tests, exploits and proves vulnerabilities safely, assesses risk, writes clear remediation reports, and advises clients on fixes. Sharp, ethical and thorough. Looking for a senior penetration-tester or offensive-security role with a firm doing serious, authorised security testing.
