I will build autonomous ai agents using langchain or crewai for your saas


About this gig
STOP BUILDING BASIC CHATBOTS. START BUILDING AUTONOMOUS AGENTS.
Are you tired of "vibe-coded" AI that fails in production? I build production-grade Autonomous AI Agents using LangChain and CrewAI that actually solve business problems.
As an Agentic Engineer, I bridge the gap between a prompt and a professional product. Whether you need an agent for automated research, lead generation, or complex data analysis, I ensure your system is scalable, secure, and logical.
What I offer:
- Custom CrewAI Workflows: Multi-agent collaboration for complex, multi-step tasks.
- LangChain Logic: Advanced RAG (Retrieval-Augmented Generation) and tool-use.
- SaaS Integration: Seamlessly connecting agents to your existing web app or API.
- Memory & State: Long-term storage so your agents remember past interactions.
- Error Handling: Robust code that doesn't "hallucinate" or break under pressure.
Why me?
I dont just "prompt"I build systems. I solve the technical debt and security gaps common in AI projects.
Message me today to turn your AI vision into a production-ready reality!

FAQ
What is the difference between an LLM and an AI Agent?
An LLM just predicts text. An AI Agent uses logic to use tools (like Google Search or your Database) to perform actual tasks autonomously.
Do I need to provide my own API keys?
Yes, you will need to provide your OpenAI, Anthropic, or Serper API keys. I will guide you on how to set these up securely.
Can the agents be integrated into my existing React/Node/Python SaaS?
Absolutely. I specialize in making AI agents "speak" to your backend via APIs or Webhooks.
Will you use CrewAI or LangChain?
It depends on your needs. CrewAI is best for collaborative roles (manager/worker agents), while LangChain is better for complex, custom logic and RAG.
How do you prevent the agents from overspending my tokens?
I implement "Max Iteration" limits and cost-tracking logic to ensure your agents don't run in infinite loops.
