Level 2
About this gig
Is your business drowning in repetitive tasks? I build Custom AI Agents and RAG-powered SaaS platforms that work for you 24/7 so you don't have to.
Unlike generic ChatGPT wrappers, I engineer production-ready agentic systems that actually act: browsing the web, processing documents, executing workflows, and integrating with your existing tools.
WHAT I BUILD FOR YOU:
- AI Agents Autonomous agents that browse, search, and execute complex workflows without human input.
- Enterprise RAG Systems Securely chat with your PDFs, databases, Notion docs, or internal knowledge base. Zero data leakage.
- AI SaaS Backends Scalable FastAPI + Next.js architectures built for real users, real traffic, and recurring revenue.
- LangGraph Multi-Agent Pipelines Advanced agent orchestration for complex, multi-step business workflows.
- Local LLM Deployments Privacy-first AI using Llama 3/4 on your own infrastructure.
TECH STACK:
- Frameworks: LangChain, LangGraph, CrewAI
- LLMs: GPT, Claude, Llama , Gemini
- Vector DBs: Pinecone, Weaviate, Chroma, Milvus, Qdrant
- Backend: Python (FastAPI), Node.js
- Frontend: React.js, Next.js
- DevOps: Docker, AWS, CI/CD pipelines

FAQ
My data is sensitive. Can we keep it private?
Absolutely. I specialize in Local RAG systems using open-source models like Llama 3, Gemma 3. This ensures your proprietary data never leaves your server or touches public APIs.
Can the AI agent be trained on my specific company data (PDFs, Website, Notion)?
Yes. I build specialized RAG (Retrieval-Augmented Generation) systems. This means the AI will answer questions based strictly on your uploaded documents and business data, ensuring accuracy and preventing "hallucinations."
Can you build an AI agent that performs tasks, not just answers questions?
Yes. Using LangGraph, I build agents that can browse the web, send emails, query databases, and update CRMs. These are "Agentic Workflows" designed to replace manual labor.
Do I need to pay monthly fees for this chatbot?
I deliver a one-time build. However, you will need your own API subscription (e.g., OpenAI or Anthropic) which typically costs a few dollars depending on usage. If you need a cost-free solution, I can set up open-source models (Llama 3) to run locally, though this requires specific hardware.
Do you offer the frontend UI as well?
Yes. I am a full-stack developer. I can build the backend intelligence (Python) and a modern, responsive frontend (React/Next.js) so you get a complete, ready-to-launch application
What is the difference between a standard Chatbot and the "AI Agents" you offer?
A standard chatbot just talks. The AI Agents I build (using LangGraph) can act. They can browse the web, send emails, schedule appointments, and update your CRM autonomously, effectively acting as a digital employee.
