I will develop custom ai agent
Sanatan
About this gig
Are you looking to automate repetitive tasks, streamline workflows, or build intelligent systems that think and act on their own?
I will design and develop custom AI agents and engineer high-performance prompts that make your AI systems smarter, faster, and more reliable using LangChain, CrewAI, AutoGen, GPT-4, and Claude.
What I can build for you:
- Autonomous AI agents that research, decide, and act
- Multi-agent pipelines where specialized agents collaborate
- Prompt engineering and optimization for any LLM
- RAG-powered agents trained on your own data
- API and database-connected agents for real business workflows
- Custom GPT wrappers with optimized system prompts
Why choose me:
- Expert in LangChain, CrewAI, AutoGen, and LangGraph
- Every prompt is tested, iterated, and optimized for accuracy
- Clean, production-ready code with full documentation
- Agents that actually complete tasks not just respond
Whether you need a single task agent, a full multi-agent system, or your existing prompts completely overhauled I deliver results that work in production.
Message me before ordering so we can scope your exact requirements.

Hey, I'm Sanatan — a self-taught backend developer with 2 years of hands-on experience building scalable, production-ready systems.
I specialize in Node.js, Express, MongoDB, PostgreSQL, Redis, Docker, and AWS. I've built real-world projects including a real-time chat app with WebSockets and Kubernetes deployment, and an affiliate deals platform with a custom deal engine and scheduled jobs.
I write clean, secure, and well-documented code — and I don't stop until you're satisfied.
Let's build something great.

FAQ
What is the difference between a chatbot and an AI agent?
A chatbot responds to questions. An AI agent reasons, plans, uses tools, browses the web, calls APIs, and completes multi-step tasks autonomously without constant human input.
What is prompt engineering and why does it matter?
Prompt engineering is the craft of writing precise instructions that get the best possible output from an LLM. A well-engineered prompt can dramatically improve accuracy, consistency, and cost efficiency.
Which frameworks do you use to build agents?
I primarily use LangChain, CrewAI, AutoGen, and LangGraph depending on your use case. We'll choose the best fit during our initial discussion.
Can you optimize prompts for my existing AI system?
Yes. I can audit your current prompts, identify weaknesses, and rewrite them for better accuracy, tone, and reliability — without rebuilding your entire system.
Can agents connect to my existing tools and databases?
Yes. I can connect agents to your CRM, databases, REST APIs, Notion, Slack, email, calendar, and more.
What is a multi-agent system?
Multiple specialized AI agents working together as a team — one researches, one writes, one reviews — each handling its role autonomously for complex tasks.
Do agents have memory between sessions?
Yes. I implement both short-term and long-term memory so your agents retain context across sessions and improve over time.
Do I need my own API key?
Yes, you will need your own API key from OpenAI, Anthropic, or Google. This keeps your data private and your usage costs under your direct control. I will guide you through the setup.
Will I receive the source code?
Yes, source code is included in all packages along with detailed code comments so you or your team can understand and maintain the system.
What if my requirements change mid-project?
I maintain clear communication throughout. Minor scope changes are handled flexibly. For larger changes we'll agree on a revised timeline and price before proceeding.
