I will build custom autonomous ai agents and rag systems with python


About this gig
Looking for an autonomous AI Agent that executes tools, remembers context, and runs complex workflows?
I am an AI engineer building custom high-performance AI Agents and hybrid RAG systems using Python.
️ What I Can Build For You:
Autonomous Tool-Calling Agents: Custom Python agents equipped with Function Calling, web search, database querying, and code execution.
Resilient Tool Execution: Robust ActionRouter architecture with parameter normalization and autonomous error self-correction.
Hybrid RAG & Long-Term Memory: Combine keyword search with vector embeddings (FTS5, SQLite, Chroma) for zero-hallucination retrieval.
Multi-Model Architecture: Seamlessly integrate Claude 3.7, DeepSeek V4.1, Gemini 3.7, or local open-weights LLMs via Ollama.
Production API Gateway: Asynchronous REST and streaming endpoints built with FastAPI.
Why Work With Me?
Clean, modular, production-grade Python code (asyncio, Pydantic, PEP 8).
Battle-tested engineering with full documentation and test suites.
100% custom-built for your specific business use case.
Please message me before placing an order to discuss your agent architecture!
