If your web application, API, or AI system has vulnerabilities, attackers will find them. My job is to find them first. I'm Md Shofiur, a Certified Ethical Hacker (CEH) and senior penetration tester with 8+ years securing applications and infrastructure across fintech, healthcare, e-commerce, and SaaS.

WordPress, Laravel, and custom CMS platforms. Network and VPS infrastructure. PCI DSS, HIPAA, and ISO 27001 compliance environments. 🔍 What makes my work different I don't run a scanner and call it a pentest. Every engagement starts with manual reconnaissance, follows a structured methodology, and ends with a report your developers can actually act on. Each finding includes a risk rating, business impact, step-by-step proof of concept, and specific remediation guidance, not just a list of CVEs. 🤖 AI security testing I'm one of the few penetration testers on Freelancer offering dedicated security assessments for AI systems.
