At Metaviz, I lead development of three platforms across real estate, travel, and service marketplaces. I work on system architecture and technical planning alongside team coordination.

I build AI-powered assistants, REST APIs, and full-stack applications, and implement automated data processing with LLM batch APIs, prompt caching, and n8n workflows.

At Haramain Travels, I designed and developed an AI-powered Umrah recommendation chatbot using n8n, OpenAI APIs, and PostgreSQL. I also supported its deployment and server configuration on AWS EC2.

At Hazen.ai, I engineered a traffic analysis system with seven specialized AI agents and reduced API costs by 30%. In my AI Powered Real Estate Marketplace project, I built property search and transaction workflows supporting a searchable inventory of over 50,000 listings.
