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.

Full-Stack AI Engineer | SaaS Architect | Blockchain & Automation Specialist $100K+ earned | 80+ projects delivered | 5 live products generating active revenue Most developers ship features. I build systems that scale, retain users, and generate revenue after launch. With 10 years of experience operating at CTO level, I have taken products from zero to paying customers for founders across the US, UK, UAE, and Singapore , across AI SaaS, Web3, automation infrastructure, and complex cloud applications. The projects I am most proud of are not the ones that launched. They are the ones still running two years later without a costly rebuild. That outcome starts with architecture decisions made on day one , before a single line of production code is written. Most technical debt, scaling failures, and security incidents are predictable. My job is to make sure they do not happen to your product. Recent work includes: ✅ RYNANCE: AI trading platform analyzing 200K+ influencers in real time, auto-executing trades on Binance, Bybit, and OKX. 4,287 waitlist users. SOC 2 compliant. 99.9% uptime. ✅ Copin: Copy-trading platform with 105,800+ trades completed in production. ✅ Baby-Sol : Served as CTO. Crossed $100M market cap in 4 weeks. Certik audited at 95%. ✅ Temoc: Web3 content distribution platform. Raised $720K. CTO and Tech Lead. Core expertise: AI & Agentic Systems — OpenAI, Claude, RAG, Voice AI, LangChain, n8n Full-Stack SaaS — React, Next.js, Node.js, Python, PostgreSQL, Supabase Blockchain & Web3 — Solidity, DeFi, NFT platforms, tokenomics design Cloud & Infrastructure — AWS, Azure, GCP, Docker, Kubernetes, CI/CD If you're looking for a technical partner who understands both engineering and product strategy, I'd be happy to discuss your project.

When your users looks for support, they need two things: someone who actually knows what's wrong, and someone who can explain the fix without making them feel stupid. That's exactly what I do. I come from a Computer Engineering background with hands-on experience in IT support and web development. What that means practically is that I don't just read from a troubleshooting script. I dig into the actual problem, figure out what's going on, and then explain it in a way that makes sense to the person on the other end, whether they're technical or not. One thing that genuinely sets me apart: I work in Arabic, French, and English. Not "conversational" level. Fluent. So if your users or customers speak any of those languages, they're getting support in their language, in their tone, without anything getting lost in translation. Here's what you can expect when we work together: - Fast understanding of new tools, platforms, and systems - Clear, jargon-free communication with end users - Technical accuracy without the technical headache - Support across Arabic, French, and English with the same quality in all three If you need someone who can handle the technical side and talk to people like a human being at the same time, let's talk. Send me a message and we'll see if I'm the right fit for what you need
