Penetration tester and cybersecurity specialist offering VAPT for web applications, APIs, and network infrastructure. I find the exploitable weaknesses in your systems before a real attacker does, prove each one with a working proof of concept, and rate it by the actual risk to your business. I've worked both sides of security. I test systems the way an intruder would — real ethical hacking, not a checklist — and as a SOC analyst I've watched those same attacks surface in the logs. So I don't just hand you a list of problems. I can tell you what a real breach would look like on your side and how to catch the next one early. Most "penetration test" reports are a scanner's output dumped into a PDF and padded with false positives. I don't work that way. Every finding is tested by hand, proven with a working PoC, and written so your developers fix what counts instead of chasing noise. What I do: - Web application penetration testing — full OWASP Top 10 coverage - API security testing for REST and GraphQL - Internal and external network and infrastructure VAPT - Vulnerability assessment with clear remediation guidance - Cloud and SaaS security assessments - SOC support: SIEM monitoring, log analysis, threat detection, incident response - Reviewing existing scan results and stripping out the false positives What I regularly find: SQL injection, SSTI, command injection, XSS, CSRF, IDOR and broken access control, authentication and session flaws, business logic abuse, API weaknesses, and server and cloud misconfigurations. Every report gives you a severity rating, the business impact in plain English, steps to reproduce, and remediation your developers can ship right away. All work is fully authorized, kept inside the agreed scope, and confidential. Send me your scope, or just tell me what's keeping you up at night, and I'll walk you through how I'd test it and exactly what you'll get back.
