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.

Most security reports end up in a drawer. Mine don't — because your developers can actually read them, understand what's broken, and fix it.
I'm a penetration tester and OSCP-certified ethical hacker. I've been hunting real vulnerabilities since 2018, first through bug bounty programs on HackerOne and Bugcrowd, and later testing web apps, APIs, mobile apps, and networks across the financial and healthcare sectors. What I care about is the same thing your future attacker cares about: the flaw a scanner skips right past.
That's the difference between what I do and an automated tool. Scanners are great at noise. I'm here for the findings that actually matter — the ones an attacker could chain together into a breach — and I show you exactly how, step by step.
Here's what working with me looks like:
🔍 Penetration Testing
Manual, hands-on testing of web apps, APIs, mobile apps, servers, and internal/external networks. I use Burp Suite Pro, Nessus, and custom scripts I've built over years of engagements — but the real work is manual exploitation, not clicking "scan."
📑 Reports You Can Act On
Every finding comes with clear reproduction steps, full request/response data, annotated proof-of-concept screenshots, CVSS ratings, and a plain-English explanation of what it means for your business. No 200-page scanner dumps.
🛠️ Remediation Guidance
Practical fixes explained so both your engineers and your decision-makers can follow them. You'll know what to fix, why, and in what order.
🔁 Free Retest
After you've patched, I re-test at no extra cost to confirm the fixes hold and no new paths opened up.
🌐 Asset Discovery & OSINT
I map your real attack surface — subdomains, exposed services, public-facing assets — and surface what attackers may already know about you, from leaked credentials to exposed data.
🤝 Straight-Talking Consulting
First time commissioning a pentest? I'll help you scope it properly, pick the right approach (black-box, grey-box, or white-box), and walk you through the whole process.
If you're protecting customer data, prepping for a compliance or vendor security review, or you just want to know where you actually stand before someone less friendly finds out — send me a message with a bit about your project. I'll tell you honestly whether and how I can help.

"I help businesses secure their digital infrastructure through professional penetration testing, security audits, and incident response support.”
With over 10 years of experience in Ethical Hacking, I have successfully led and executed hundreds of security audits, penetration tests, and red team engagements for clients ranging from multinational corporations with thousands of assets to nimble startups seeking a security edge in their competitive landscape.
My expertise lies in hands-on offensive security, vulnerability assessment, and deep knowledge of both legacy and modern technology stacks—understanding their common pitfalls and security flaws.
Below is an overview of the services I offer:
✅Penetration Testing Engagement
Comprehensive manual and automated testing of websites, applications, servers, and infrastructure within the defined scope. This includes internal and external network testing, performed using industry-leading tools such as Burp Suite Professional, Nessus, and custom-developed scripts and utilities tailored from previous engagements.
✅Professional Reporting & Risk Analysis
A detailed, professionally written report outlining each identified vulnerability, complete with:
-Step-by-step exploitation methodology
- Full HTTP requests/responses
- Screenshots and Proof-of-Concepts
- Standardized "CVSS v4.0" risk ratings
- Business impact and affected asset ownership
✅Remediation Advice & Guidance
Actionable, tailored remediation guidance for every identified security issue. I provide clear explanations of the risk associated with each finding and offer best-practice solutions to mitigate or eliminate the threat.
✅Asset Discovery & Mapping
Active and passive reconnaissance to determine the breadth of your digital footprint. Includes:
-Subdomain enumeration
-Port and service discovery
-Identification of public-facing assets susceptible to external threats
✅Free Retest & Validation
Included in the service is a complimentary re-evaluation of previously identified vulnerabilities to verify that remediation efforts have been successfully implemented and that no alternate exploitation paths exist.
✅OSINT Reconnaissance
Extensive Open-Source Intelligence (OSINT) gathering to identify publicly available data that could pose a threat, including:
-Breached email addresses and associated credentials
-Data circulating on forums or the dark web
-Leaked documents or sensitive metadata
Access to a curated repository of over 4 billion records enables comprehensive visibility into your
company’s exposure.
✅Pre-Engagement Briefing
I am available for consultation sessions to:
-Define and refine the Scope of Work (SoW)
-Determine the appropriate engagement type (black-box, white-box, or grey-box)
-Establish access requirements and test scheduling
-Provide guidance for organizations conducting a penetration test for the first time
✅Post-Engagement Debriefing
After the assessment, I offer detailed walkthrough sessions of the findings. These sessions include:
-Clarification of technical findings and their real-world impact
-Prioritization of vulnerabilities based on risk
-Strategic recommendations to strengthen your overall security posture
With a strong track record of delivering high-impact, actionable security insights, I am committed to helping organizations identify, understand, and mitigate their risks in today’s complex threat landscape.
