About Vu Tuan

I help companies make the leap into Generative AI and operational efficiency. My core business? Transforming your data and documents into intelligent assistants (RAG) and automating time-consuming processes to save you valuable time.

🧠 My Areas of Expertise

Want to leverage your internal data (PDFs, databases, business repositories) without data leakage risk?
- Creation of high-performance RAG assistants (e.g., HR Assistant, PDF Expert).
- Development of autonomous conversational agents connected to your tools (WhatsApp integration via Twilio, Webhooks).
- Mastery of LLMs & Frameworks: LangChain, Llama 3.1, Groq API, OpenAI, Claude, ChromaDB (Vector Database).

2. Process Automation & Python Scripts 🚀
Tired of repetitive tasks? Entrust them to a robot.
- AI Automation: Integration of AI and NLP components into your workflows.
- Custom Script Development: Automation of complex workflows in Python.
- Robust Deployment: Industrialized scripts locally or on the Cloud (Docker, Azure, VPS).

My Technical Stack
- Languages: Python, SQL, C
- AI / GenAI / ML: LangChain, PyTorch, TensorFlow, Llama, Hugging Face, Scikit-Learn
- Backend & API: FastAPI
- DevOps & Deployment: Docker, Git, CI/CD, Azure

🤝 Why Work With Me?
- ROI-Oriented Approach: AI must serve your business. I simplify technical jargon to offer you simple, useful, and immediately actionable tools.
- Production Guarantee: Thanks to my engineering background, your applications are delivered packaged (Docker), documented, and ready to use.
- Transparency and Responsiveness: Clean code (projects visible on my GitHub), respect for deadlines, and smooth communication.
