Jamil Fayad — Full Stack Developer & AI Engineer
Strategic and accomplished Full Stack Developer and AI Engineer with extensive expertise in Python, intelligent agent design, and secure cloud-native applications. Specialized in building production-ready ML systems with proven experience in computer vision, recommendation engines, and real-time tracking solutions.
What I build
Full-stack web applications
End-to-end product builds — REST APIs, relational data models, and React frontends deployed on cloud infrastructure you can actually operate.
Computer vision & AI/ML systems
Object detection, model optimization, and retrieval-augmented pipelines — trained, quantized, and wired into a product, not left in a notebook.
Security-hardened backends
Penetration-tested APIs with injection, XSS, and DoS mitigations built in from the first commit — not bolted on before launch. Audits run on CAI, my own autonomous penetration-testing framework.
Workflow & agent automation
n8n pipelines and multi-agent systems that take repetitive engineering work off your team's plate.
Experience
Full Stack Developer & AI Engineer — Freelance Full Stack Web Developer — Independent / Remote (Jun 2023 — Present)
- Architect and manage all aspects of full-stack development to deliver production-ready applications achieving 99.5% uptime and serving 500+ active users with consistent performance and reliability.
- Design and implement AI-powered solutions including ingredient detection systems achieving 92% accuracy across 50+ categories using YOLO, reducing manual processing time by 60% through optimized ML pipelines.
- Develop and execute comprehensive security strategies implementing DoS mitigation, XSS protection, and SQL injection prevention, maintaining zero security breaches over 18 months of production operation.
- Lead the complete development lifecycle from concept to deployment on Azure App Service, managing React frontend, Django backend, PostgreSQL databases, and ML components with automated testing and monitoring.
- Conduct regular assessments of application performance, implementing optimization strategies that reduced inference time from 3.2s to 1.3s through model quantization and intelligent caching mechanisms.
- Build and maintain multi-language support systems (English, Arabic, French) using Django's i18n framework, ensuring seamless user experience across diverse user demographics.
- Collaborate with stakeholders to transform business requirements into technical specifications, delivering high-quality solutions within budget and timeline constraints.

Questions clients actually ask
Do you work with businesses in the UAE, Saudi Arabia, or other GCC countries?
Yes. Based in Lebanon, working remotely with clients worldwide — including the UAE, Saudi Arabia, Qatar, Kuwait, Bahrain, and Oman. Everything is scoped, delivered, and supported remotely.
Do you build custom websites and web applications?
Yes — end-to-end product builds: REST APIs, relational data models, and React frontends deployed on cloud infrastructure you can actually operate. Not a template, a custom build.
Can you build an AI agent or automation for my business?
Yes. Single-task agents (support triage, lead qualification, booking) wired into your CRM, WhatsApp, or site, built on n8n and LLM integration, or full multi-agent systems for larger workflows.
Do you work on computer vision or object detection projects?
Yes — training, optimizing, and deploying object detection and recognition models (YOLO, PyTorch) into a working product, not left as a notebook demo.
Can you run a security audit or penetration test on my application?
Yes. Backends are built with injection, XSS, and DoS mitigations from the first commit, and I maintain CAI, a dedicated autonomous penetration-testing framework covering web, API, cloud, and AI/ML attack surfaces.
Do you support Arabic and English?
Yes — EN/AR localization is available where scoped, relevant for GCC and wider Arabic-speaking audiences.
What does a project cost?
Fixed fees, scoped before anything starts: single-workflow automation from $1,500–$4,000, a full web app rebuild from $4,000–$9,000, or both combined from $5,000–$11,500.
