Hugo Brua

Senior AI Engineer, CTO, and co-founder of yassistant.ai, I assist startups, SMEs, and large corporations in designing and deploying custom generative AI solutions. My expertise: LLMs (OpenAI GPT-4, Anthropic Claude, Mistral, Llama), multi-agent systems, RAG, fine-tuning, prompt engineering, vector databases, embeddings, and intelligent automation.

What I can bring:

- Complex AI architectures (multi-agent, advanced RAG, autonomous AI Agents).

- Custom AI platforms with LangChain, LlamaIndex, Hugging Face: chatbots, multimodal analysis (text, voice, image), voice assistants.

- High-ROI AI automations: quotes/invoices, scraping, AI-generated SEO articles, WooCommerce and business API integrations.

- Fine-tuning of open-source LLMs (Llama, Mistral) for specific use cases.

- MLOps and production-ready deployment (Docker, GCP/AWS).

- Training and consulting on explainable AI (XAI, LIME, SHAP).

Key achievements:

- GoodSpeakVR: public speaking analysis (NLP + computer vision + audio).

- Vintage-expert: AI platform for vintage object analysis (fine-tuning + multi-agent).

- Architecture firm platform: voice commands + autonomous multi-agents (invoicing, reminders, minutes of meeting).

Stack: Python, PyTorch, LangChain, LlamaIndex, OpenAI, Anthropic, Hugging Face, FastAPI, vector databases, Docker, GCP.

My dual background in AI + cybersecurity (ex-Orange Cloud Security, ex-Thales, CentraleSupélec) guarantees high-performance, scalable, and secure solutions.
