You will get RAG Chatbot Development | Knowledge Base Bot | GPT, Claude, Pinecone
Project details
Your team is buried in PDFs, contracts, and reports — searching for answers that should take seconds, not hours. That's not a knowledge problem, it's a retrieval problem, and it's costing you real money every week.
I build custom RAG (Retrieval-Augmented Generation) chatbots powered by OpenAI API and Claude API that answer questions straight from YOUR documents, not generic or hallucinated responses.
What your RAG chatbot can do:
→ Parse and index PDFs, contracts & internal docs (Document Parsing, OCR)
→ Hybrid search — semantic + keyword retrieval for accurate answers
→ Store and query embeddings using Pinecone Vector Database
→ Maintain custom agent RAG memory across long conversations
→ Deploy securely on AWS Cloud (S3, ECS, CloudWatch)
→ Connect via API Integration, Webhooks & REST API to your CRM Software
→ Automate workflows with n8n, Zapier, or Make.com
Built as an AI Agent using LangGraph and FastAPI for production-grade performance, with LLM Prompt Engineering tuned to your domain — Finance, Operations, Risk, or Support.
This is not a template. Every RAG chatbot is custom-built, tested, and delivered with full documentation and a walkthrough.

AI Intelligence Discussion
Sakib delivered quality work and was able to resolve several challenging issues in our AI backend within the expected timeframe. He demonstrated solid technical knowledge, communicated proactively, and integrated well with our GitHub workflow. He took ownership of problems instead of waiting for detailed instructions and was willing to iterate until everything worked as expected. We’d happily work with him again.

WHAT I DO FOR YOU :
AI Chatbot & Agentic AI Development
Custom AI Chatbot and Agentic AI systems for website, WhatsApp, and CRM integration. RAG Chatbot development with vector search and document parsing, so your AI Agent answers from your own internal documents instead of generic guesses. Built with LangGraph, OpenAI API, OpenAI GPT, and Claude (Anthropic).
AI Voice Agent & Voice Assistant Systems
Inbound and outbound AI Voice Agent and Voice Receptionist builds using Twilio API, Vapi, Retell AI, and ElevenLabs. Natural conversation flows with low-latency Speech to Text and Text to Speech, appointment setting, lead qualification, and human call handoff via SIP and phone system integration.
AI Workflow Automation
End-to-end Automated Workflow builds in n8n, Make, and Zapier connecting your AI Agent to CRM Software, Google Sheets, Airtable, Google Drive, and Gmail Automation. API Integration and Webhooks between tools so nothing needs manual updating — built with Python, JSON, and FastAPI.
CRM Automation & GoHighLevel (GHL)
GoHighLevel setup for CRM, lead pipelines, and automation — including GHL Voice AI configuration, workflows, and appointment booking automation for customer support automation and business process automation.
RAG & Document Parsing Systems
RAG (Retrieval-Augmented Generation) pipelines with Pinecone Vector Database, OCR image parsing, and document parsing automation so your AI Agent references your real business data with LLM Prompt Engineering behind every response.
TECH STACK:
n8n, Make, Zapier, GoHighLevel, Twilio API, Vapi, Retell AI, ElevenLabs, Python, JSON, FastAPI, LangGraph, OpenAI API, OpenAI GPT, Claude, Anthropic, Pinecone, Vector Database, REST API, Webhooks, Google Workspace, Google Sheets, Airtable, WhatsApp Business API, Machine Learning.
WHY WORK WITH ME:
✔ Clear scoping before development — no wasted hours
✔ Production-ready AI Agent and AI Chatbot systems, not prototypes
✔ Documentation handed over so your team can maintain the system
