Project details

Have an AI startup idea or want to add Generative AI features to an existing SaaS product?

I will build a production-ready AI SaaS application using LLMs, RAG, AI agents, Python, FastAPI, React or Next.js, databases, APIs, authentication, dashboards, and cloud deployment. Your product can include AI chat, document intelligence, semantic search, workflow agents, structured outputs, model routing, user roles, usage limits, subscriptions, Stripe billing, analytics, and admin controls.

I can integrate OpenAI, Claude, Gemini, Llama, Mistral, vector databases, and third-party APIs within a secure, scalable architecture. You will receive technical planning, backend APIs, responsive frontend, logging, monitoring, Docker setup, deployment, and documentation.

Ideal for AI startup MVPs, enterprise copilots, knowledge platforms, document AI, AI chatbots, and subscription-based AI products.

Improve LLM Prompts and Structured JSON Responses He did a great job improving our LLM prompts and structured JSON responses. He improved the OpenAI API output, prompt instructions, function calling flow, and response accuracy. The final results are now cleaner, more consistent, and easier to use in our app. Clear communication, fast delivery, and strong understanding of prompt engineering, structured output, and Large Language Models.

Improve RAG Pipeline Accuracy Using OpenAI and LangChain We had a great experience working with him on our RAG pipeline. He fixed the LangChain retrieval flow, improved the OpenAI responses, adjusted embeddings and vector search, and made the answers much more accurate. Clear communication, fast delivery, and strong understanding of RAG, semantic search, and AI systems.

Fix and Improve a Python RAG Chatbot Using OpenAI and LangChain Great work fixing our Python RAG chatbot. He improved the LangChain setup, OpenAI API flow, document retrieval, and response accuracy. Fast delivery, clear communication, and solid understanding of RAG, embeddings, vector search, and AI chatbot development.

AI Developer Needed – Gen AI, RAG, LLM & AI Chatbot The collaboration went smoothly. He handled the AI chatbot and RAG setup well and understood the requirements without much back and forth. The implementation was smooth, and the system worked as expected for document-based Q&A. Communication was consistent and easy throughout the project. Overall, a reliable and skilled freelancer - would work again.
