I build scalable backends and AI agent systems using Django, FastAPI, and modern API design. My work focuses on creating intelligent automation, stable infrastructures, and backend systems that help businesses cut costs, scale reliably, and handle thousands of interactions with ease.
I'm Ezz, a top-rated backend developer. I’ve helped clients reduce support workloads by 70–80%, speed up backend performance by more than 95%, and automate entire operational flows with custom AI agents.
What I Do
I design and develop:
- AI agents, chatbot systems, and automated workflows
- Backend architectures using Django, FastAPI, Celery, Redis, and cloud platforms
- REST APIs and microservices built for performance, security, and scalability
- Stripe billing systems (checkout, subscriptions, Connect payouts)
- User authentication, role management, and admin tooling
- Monitoring, logging, and performance optimization for production systems
I work with modern AI tooling (LangGraph, LLM caching, Cursor, GitHub Copilot) to deliver fast, reliable results with clean, maintainable code.
What Clients Say
“Ezzeddin helped us reduce human support efforts by 70 to 80% with a fully automated AI agent system.” “Our latency dropped by 95.5% thanks to the backend optimization he delivered.” “We automated an entire department with his help — major boost in workflow efficiency.”
