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.
