OSCP & CEH-certified Penetration Tester with 8+ years of hands-on experience in Web, Mobile (iOS/Android), API, and Cloud security testing. 65+ projects delivered, 100% Job Success Score, Top Rated on Upwork. I help SaaS companies, healthcare platforms, FinTech, E-commerce and EdTech startups find real, exploitable vulnerabilities before attackers do, through manual penetration testing that goes far beyond automated scans. — What makes my testing different — I focus on real exploitation, not theoretical findings. Automated scanners miss business logic flaws, broken access control, and chained vulnerabilities. My OSCP-trained approach simulates how a motivated attacker would actually compromise your application, then documents the path so your developers can fix it for good. Every engagement includes a free retest after remediation, so you know the fix worked. — Core services — • Web Application Penetration Testing (OWASP WSTG v4.2 methodology) • Mobile App Security Testing for iOS & Android (OWASP MASVS / MASTG) • API Security Testing — REST, GraphQL, OWASP API Top 10 • Cloud Security Reviews — AWS / GCP / Azure misconfiguration testing • Source Code Security Review (PHP, Node.js, Python) • AI / LLM Security — Prompt Injection, Data Leakage, OWASP LLM Top 10 • WordPress & PHP Application Hardening • WAF Bypass Testing & Detection Engineering — Tools & methodologies — Burp Suite Professional, Frida, Nmap, sqlmap, Metasploit, OWASP ZAP, Nuclei, Genymotion, MobSF, OWASP WSTG, OWASP MASVS, MITRE ATT&CK, NIST SP 800-115. — Industries I've worked with — Healthcare & medical devices (compliance-grade pentest + documentation), EdTech mobile platforms (iOS app dynamic analysis with Frida, Keychain audit), SaaS startups (full-stack web + API testing), e-commerce (WAF bypass, payment flow security). — Compliance support — GDPR, PCI-DSS, ISO 27001, SOC 2, HIPAA — I provide the technical evidence and remediation documentation auditors expect. — How I work — 1. Send me your application URL or scope description, I'll review it and respond within 24 hours 2. Fixed-price or hourly proposal with clear deliverables, no surprises 3. Manual testing with detailed PoC for every finding 4. Executive summary + technical report (CVSS-scored, remediation-ready) 5. Free retest after your team applies the fixes — Certifications — • OSCP — Offensive Security Certified Professional • CEH — Certified Ethical Hacker • MSc in Information Systems & Network Security — University of Milan Send me your application URL or a brief scope description, and within 24 hours you'll get a focused assessment and a clear, fixed-price estimate.

With 10+ years of experience across AI development, cybersecurity, and blockchain, I bring a combination most freelancers can't offer I think like an engineer and a hacker at the same time. ✦ CYBERSECURITY Certified OSCP | CRTO | eWPTXv2 I've led hundreds of penetration tests and security assessments for startups, enterprises, and regulated financial institutions. - Web Application & API Penetration Testing (OWASP Top 10, business logic flaws) - Network Penetration Testing Internal & External - Active Directory Security Assessments - Red Team & Assume Breach Engagements - Cloud Security Assessments - MITRE ATT&CK–based adversary emulation - Executive-ready reports, proof-of-concept evidence & free retests included All testing is manual-first no scanner noise, only real exploitable findings. ✦ AI DEVELOPMENT I've shipped full-scale AI products handling real users and real workflows. Here's what I build: - AI video generation platforms custom avatar creation, script-to-video, multilingual dubbing, and export-ready outputs - AI voice cloning & text-to-speech systems for content creators and media companies - AI avatar & digital human platforms for marketing, training, and e-learning use cases - Enterprise AI automation platforms natural language command execution, multi-task AI agents, and cross-department workflow automation - AI chatbots & virtual assistants integrated with WhatsApp, Telegram, Slack, and web apps - Custom LLM-powered tools document Q&A, internal knowledge bases, and AI copilots for SaaS products - RAG (Retrieval-Augmented Generation) pipelines for accurate, context-aware AI responses - AI content generation tools for social media, marketing copy, and video scripts - End-to-end AI SaaS products with subscription billing, user dashboards, and API integrations ✦ BLOCKCHAIN & WEB3 - Smart contract development & security audits - DeFi protocol builds and integrations - Web3 application development with security-first architecture - NFT platform development and token contract reviews ✦ WHY THIS COMBINATION MATTERS When I build your AI product, I'm already thinking about how it gets attacked. When I audit your systems, I understand the modern tech stacks powering them. That dual perspective is rare and it raises the quality bar of everything I deliver. If you want an AI builder who thinks like an attacker, or a security professional who ships real products — let's talk.

Organizations don't fail because they lack technology. They fail because security weaknesses remain undiscovered until attackers exploit them.
