About this gig
I build reliable, production-ready AI agents and RAG systems that actually work in real-world applications not demo-only chatbots.
If you are a startup, founder, or team looking to:
- Build an AI agent on your own data
- Reduce hallucinations and improve grounding
- Deploy a scalable RAG or multi-agent system
- Integrate AI into an existing product
you are in the right place.
What I can build for you
- RAG pipelines using your documents, databases, or APIs
- AI agents using LangChain and LangGraph with tool calling
- Multi-agent workflows for complex reasoning tasks.
- Chatbot integration.
- Model fine-tuning, light fine-tuning, LoRA, prompt optimization
- Cloud deployment with basic monitoring
- Cost and latency optimization for production use
What you will get
- Clean, well-structured source code
- A functional web-based AI system.
- Clear explanations and usage instructions
- Optional evaluation report with custom metrics
Why work with me
- Focus on low hallucination, predictable outputs
- Production-first mindset.
- Clear communication and realistic timelines.
- Flexible scope depending on your needs.

LangGraph & RAG Specialist | Production AI Agents & LLM Engineer
Struggling with hallucinating LLMs, weak retrieval, or prototypes that fail in production? I build reliable, low-cost LangGraph multi-agent systems and grounded RAG pipelines that ship and scale.
Live proof: SciNets.in — production platform processing 9–10 papers/run at ~$0.10 using graph-constrained multi-hop reasoning, custom eval metrics (symbolic depth, grounding stability), full stack (FastAPI, Postgres, Docker, OAuth).
Tech: LangGraph, LangChain, RAG, PyTorch/Transformers, FastAPI, Docker, Python.
FAQ
Do you use my private data securely?
Yes. Your data is used only for your project and is never shared, reused, or stored beyond development unless explicitly required for deployment. NDA-friendly workflow.
What type of data can you work with?
I can work with PDFs, Word files, text files, databases, APIs, CSVs, and web content. If your data is complex or unstructured, message me first so I can suggest the right approach.
Will the AI give accurate answers or hallucinate?
I focus on grounded RAG and agent design to minimize hallucinations. While no AI system is 100 percent perfect, I design systems with retrieval validation, prompt constraints, and evaluation metrics to ensure predictable and reliable responses.
Do you deploy the system or only provide code?
Both. I can deliver source code only or fully deploy the system to the cloud with basic monitoring, depending on the package or selected extras.
Can you integrate this into my existing app or website?
Yes. I can integrate the AI system into your existing backend, frontend, or API-based application.
Do you provide model fine-tuning?
Yes. I offer light fine-tuning / LoRA / prompt optimization as an add-on. Full large-scale training is not included unless discussed beforehand.
Can you customize the solution beyond the listed packages?
Yes. If your requirements don’t fit neatly into a package, contact me and I will propose a custom offer.
Will I get the full source code?
Yes. You will receive complete source code for the delivered system unless explicitly stated otherwise.
