I will build semantic search, rag chatbot , llm pipeline fastapi, faiss and custom ai


About this gig
I design and deploy end-to-end NLP systems: from data cleaning and embedding generation to vector indexing, retrieval strategies, prompt engineering (RAG), and a containerized API (FastAPI + Docker). Typical deliverables include an embedding pipeline, FAISS/Chroma index, retrieval logic, simple web/API demo, and documentation for deployment. I focus on accuracy, latency, and reproducibility so your system is ready for integration.

FAQ
What do you need from me to get started?
Please provide your project goals, dataset or data source (if available), target use case (e.g., chatbot, semantic search, Q&A), and any deployment preferences (cloud provider, API specs, etc.).
Which technologies do you use?
I primarily use Python, FastAPI, LangChain, FAISS/Chroma, OpenAI or Hugging Face embeddings, and Docker for containerization. I can also integrate Redis, Weaviate, or Pinecone if required.
Do you provide training or fine-tuning of models?
Yes, I can fine-tune or adapt transformer models (BERT, SentenceTransformers, etc.) using your labeled data if needed, depending on the Gig package or custom offer.
Will you include vector indexing and retrieval logic?
Absolutely. Each project includes embedding generation, FAISS/Chroma indexing, and retrieval logic optimized for latency, accuracy, and scalability.
Do you build RAG (Retrieval-Augmented Generation) systems?
Yes — RAG pipelines are a core part of my service. I integrate retrieval layers with LLM-based generation for accurate, context-aware responses.
Can you integrate my system with ChatGPT or other APIs?
Yes. I can connect your pipeline to OpenAI, Anthropic, or local models (Ollama, Hugging Face Transformers) depending on your preferred setup.
Is my data secure and confidential?
100%. I follow strict confidentiality practices — your datasets, models, and APIs remain private and are never shared or reused outside your project.
Do you provide documentation and reproducibility?
Yes — every delivery includes code documentation, setup guides, and Docker instructions for reproducible deployments on your infrastructure.
