I will build a custom ai chatbot with rag, langchain and openai

Need an AI feature that actually works in production, not just a notebook demo?

Im an engineer with 9+ years of shipping real software. I build custom AI and machine learning solutions from your data all the way to deployment.

What I can do:

Fine-tune LLMs (Llama, Mistral, Qwen, GPT) with LoRA/QLoRA on your data

RAG chatbots over your documents (LangChain, LlamaIndex, vector databases)

Deep learning with PyTorch/TensorFlow: image classification, object detection, NLP, forecasting

Classic ML: classification, regression, clustering (scikit-learn, XGBoost)

Deployment as an API (FastAPI, Docker) or on-device in iOS apps (Core ML)

Data cleaning, model evaluation and clear result reports

Why work with me:

Clean, documented code that you fully own

Fast, clear communication with regular updates

Production mindset: models built to run inside real apps

Revisions until it matches the agreed scope

Please message me before ordering. Tell me your goal, your data and your timeline, and Ill reply with a clear plan and quote.
