I will develop enterprise ai agent workflows and fastapi backend
Ozenc Donmezer
About this gig
Are you looking to move beyond simple AI scripts and build production-ready, enterprise-grade AI applications?
As a Senior Backend & AI Architect, I apply Systems Thinking to bridge the gap between complex LLMs and stable, high-scale async architectures. I don't just plug in APIs; I design robust infrastructures that eliminate bottlenecks.
What I Offer: Production-Ready AI Agents: Autonomous workflows using LangChain, CrewAI, and n8n orchestration. Enterprise RAG Systems: High-performance retrieval with advanced PostgreSQL and pgvector optimization. Scalable Python Backend: High-scale, asynchronous architectures powered by FastAPI. Production Essentials: Secure data flows, Redis caching, and Docker containerization.
️ Tech Stack: Python (FastAPI, Flask), LangChain, CrewAI, n8n, PostgreSQL (pgvector), Redis, Docker, Node.js.
Building resilient, secure, and scalable AI backends requires architect-level engineering. Lets build your system the right way.
Contact me before ordering to discuss your architecture!

FAQ
Which AI models and frameworks do you specialize in?
I deeply work with OpenAI (GPT-4o), Anthropic (Claude 3.5 Sonnet), and open-source models. For orchestration, I specialize in LangChain, CrewAI, and n8n to build autonomous, multi-agent workflows.
Is the backend architecture production-ready and scalable?
Yes. I don't just write scripts. I design enterprise-grade, asynchronous architectures using FastAPI and optimize PostgreSQL (pgvector) to ensure your system handles high-scale data flows securely.
Do you provide the complete source code and documentation?
Absolutely. Full source code delivery with clean, well-commented architecture and deployment-ready Docker configurations is standard across all packages.
Can you integrate these AI agents into my existing database or infrastructure?
Yes, I apply Systems Thinking to seamlessly connect advanced AI layers with your current PostgreSQL, MongoDB, or legacy backend without disrupting your existing operations.
