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.

Data Scientist | AI & ML Engineer | Data Analyst | Python | SQL | Power BI | LLM & RAG Hi, I'm Shahab 👋 Most businesses are sitting on data they're not using and drowning in manual work they shouldn't be touching. I build the machine learning models, AI applications and dashboards that fix both and I make sure they actually ship, not just sit in a notebook.

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.
