I help startups, SaaS companies, and enterprises identify security vulnerabilities before attackers do. With 5+ years of cybersecurity experience, I specialize in manual penetration testing, application security, API security, cloud security, compliance assessments, and privacy audits.
I have worked with organizations across the United States, United Kingdom, Germany, and Canada, delivering security assessments aligned with international standards and industry best practices. My assessments have uncovered critical vulnerabilities including Account Takeover, Remote Code Execution (RCE), IDOR, Authentication & Authorization flaws, Business Logic vulnerabilities, SSRF, XSS, CSRF, SQL Injection, Sensitive Data Exposure, Security Misconfigurations, and Insecure API Implementations.
My Services
Penetration Testing
• Web Application Penetration Testing (OWASP Top 10)
• Mobile Application Security Testing (Android & iOS)
• REST & GraphQL API Security Testing

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.

I find and fix security holes in web applications, APIs, and AI systems. I bring an MS Cyber Security degree from PIEAS and 9+ years building production software, so I test like an attacker and fix like a developer. I look for problems at the code level, not just what an automated scanner prints out.
My MS thesis research found a novel denial of service attack in LoRaWAN IoT networks and built a working mitigation. Most security freelancers cannot read your source code. I can, because I spent years writing the kind of code I now test.
