I will fine tune a large language model on your custom data
Lorenzo Cavallo
About this gig
I will fine-tune a large language model (LLM) on YOUR custom data so it responds in your style, knows your domain, or performs your specific task.
WHAT YOU GET:
- A fine-tuned LLM (Mistral, Llama, or Qwen) trained on your data
- LoRA adapter weights you can use locally or deploy
- A Python inference script - ready to run
- Clear documentation on how to use it
I WORK WITH:
- Custom chatbots trained on your docs or FAQs
- Domain-specific models (legal, medical, coding, support)
- Style transfer (match your brand voice)
- Task-specific models (classification, extraction, summarization)
I use real ML training - PyTorch, LoRA/QLoRA - not just prompt engineering. Your data stays private. You get the model files and scripts.
TECH STACK:
- PyTorch, Hugging Face, LoRA, QLoRA
- Models: Mistral-7B, Llama-3, Qwen, custom
- Training: SFT, DPO, RLHF
- Deployment: vLLM, llama.cpp, FastAPI
Message me before ordering so I can confirm your use case fits. I respond within 3 hours.

I'm an AI/ML engineer specializing in LLM fine-tuning, AI chatbots, and Python automation. I build neural networks from scratch in PyTorch - not API wrappers.
I've built an autonomous AI system with 256+ modules: a from-scratch GPT transformer, multi-agent orchestration, RAG memory, and GPU fine-tuning pipeline.
Services: LLM fine-tuning on your data, RAG chatbots from your docs, custom AI agents, FastAPI backends.
Clean, documented code. Message me about your project.
FAQ
What data do I need to provide?
Any text data works: documents, FAQs, chat logs, articles, CSV, JSON, or TXT files. The more relevant data you have, the better the model. Message me and I'll tell you if your data is suitable.
Which model do you use
I work with Mistral-7B, Llama-3, Qwen, and other open-source models. I'll recommend the best one for your use case after reviewing your data.
Can I run the model locally?
Yes. I deliver LoRA adapter weights and a Python inference script. You can run it on your own machine or server. I'll include setup instructions.
Is my data private?
Yes. Your data is only used to train your model. I do not share or reuse it. You receive all the model files.
