Build a customized chatbot

About this ad

I deliver production-ready AI chatbots that don’t just reply, they understand, remember, and retrieve the right answers using advanced RAG and graph-based intelligence.

With 5+ years of industry experience and more than 20 successfully developed chatbots, I help businesses automate support, streamline operations, and unlock real value from AI.

Using LangChain, LangGraph, and Graphiti, I design chatbots that can remember long conversations, reason over complex data, and retrieve precise answers from PDFs, databases, websites, and private knowledge bases. I work with top LLM models, including GPT-4o / GPT-4o-mini, Gemini Pro & Flash, Claude Opus & Sonnet, along with vision models like Qwen, LLaVA, and DeepSeek.

I also integrate chatbots with third-party APIs such as Slack, Google Sheets, WhatsApp, Shopify, and custom REST APIs to automate workflows and fetch real-time data securely.

I am a Gold Medalist in Master’s in Computer Science, bringing strong academic foundations together with hands-on production experience to deliver reliable, scalable, and business-ready AI solutions.

What you’ll get:
1.High-accuracy RAG-based AI chatbot
2.Long-term conversation memory using graph intelligence
3.Secure, scalable, production-ready deployment
4.Seamless third-party API integrations
5.Clean, maintainable, and well-documented code

If you’re looking for an experienced AI engineer who delivers results, not demos, let’s discuss your project and build a chatbot that truly works for your business.
