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.
