I will build custom ai agents, ai chatbots and rag systems for your business


About this gig
AI agents that actually work - not demos, production systems.
I'm Aftab, an AI engineer specializing in LLM-powered agents, chatbots and RAG systems built with OpenAI, Claude, LangChain and LangGraph - backed by real full-stack engineering (Python, FastAPI, Next.js).
What I build:
- Custom AI chatbots trained on your data (website, docs, PDFs, DB)
- RAG systems with vector search (Pinecone, pgvector, ChromaDB)
- Autonomous & multi-agent systems (LangGraph, CrewAI)
- AI customer support, lead-gen and booking assistants
- Voice assistants & AI calling bots
- AI SaaS MVPs - a full app around your AI idea
- Integrations: WhatsApp, Slack, web, CRM, your API
Every delivery includes deployment (AWS/Azure/GCP/Vercel), testing against real conversations, and docs so your team can maintain it.
Why me:
- Production engineering, not prompt-only demos
- Accurate RAG: chunking, evals, hallucination control
- Clean handover: code, docs, walkthrough video
Tell me what you want automated - I'll reply within the hour with a concrete approach and honest scope.

FAQ
Which AI models do you use?
OpenAI (GPT), Anthropic Claude, Gemini or open-source models - chosen for your accuracy, cost and privacy needs. API usage runs on your own keys, so you keep control.
Can the chatbot answer from my company data?
Yes - that's RAG: your docs, website or database are indexed into a vector store so answers come from your content, with hallucination control.
Can you integrate with WhatsApp or my CRM?
Yes: WhatsApp Business API, Slack, Telegram, website widgets, HubSpot and custom APIs/webhooks.
Do I own the code?
100%. Delivered to your repo with documentation and a walkthrough video. No lock-in.
What do you need from me to start?
A short description of the use case, sample data or docs, and API keys (or I help you set them up). I confirm scope before starting.
