AI Chatbot & LLM App Development

About this Gig

I build custom AI chatbots and LLM-powered applications that actually solve a business problem — not just demos. Whether you need a chatbot that answers questions from your own documents, an AI assistant inside your website or app, or a smart automation powered by GPT, I can design, build, and deploy it end to end. What I can build for you: - Custom AI Chatbots — trained on your data (PDFs, docs, website, knowledge base) so they answer accurately using YOUR information, not generic replies. - RAG Systems (Retrieval-Augmented Generation) — chatbots that pull correct answers from your documents using vector databases like Pinecone, so responses stay factual and reduce hallucination. - AI Agents & Workflows — multi-step AI agents (using LangChain + LangGraph) that can plan, use tools, and complete tasks like research, support replies, or content generation. - LLM Integration into your existing product — add OpenAI / GPT features such as summarization, Q&A, text generation, or smart search into your app or website. - Voice features — speech-to-text and text-to-speech for voice-based assistants. Tech I work with: OpenAI API, LangChain, LangGraph, Pinecone (vector DB), Python, FastAPI, Next.js / React, PostgreSQL, and cloud deployment (AWS, Docker, CI/CD). Proof of work: I have built and deployed LingosAI (lingosai.com) — a full production AI tutoring platform using agent-based AI, RAG memory, and OpenAI — and Assistly, a chatbot generator app powered by the ChatGPT API. I focus on clean, production-ready code, clear communication, and delivering something you can actually use in your business.

Requirements

To start quickly and deliver the right solution, please share the following: 1. Your goal — In simple words, what should the chatbot or AI app do? (Example: "answer customer questions from our product manual" or "summarize support emails") 2. Your data / content — Any documents, PDFs, website links, FAQs, or knowledge base the AI should use to answer. (If you don't have this ready, I can guide you.) 3. Where it should live — Should it be a website widget, a standalone web app, inside your existing app, WhatsApp/Telegram, etc.? 4. Preferred AI provider (optional) — If you already use OpenAI, Azure, or another provider. If not, I'll recommend the best fit for your budget. 5. API keys / accounts — If the project needs OpenAI or any paid service, you'll need an account. I'll tell you exactly which ones and help you set them up. 6. Examples you like (optional) — Any chatbot or app you've seen that matches the style or features you want. 7. Timeline & budget — Your target deadline and budget range, so I can suggest the best plan. Don't worry if you don't have everything ready — just share what you have, and I'll guide you through the rest step by step.
