About Nathan

AI Software Engineer, I develop internal tools for technical SMEs: AI agents, RAG documentary assistants, AI automations, pre-quotes, intelligent catalogs, and custom business interfaces.

I can be involved in both framing and construction: understanding your business needs, identifying what needs to be automated with traditional rules or generative AI, and then developing a complete solution with a web interface, backend, database, REST API, documents, sources, and integration with your existing tools.

What I can build:
  • AI Agent / RAG documentary assistant connected to your PDFs, technical datasheets, procedures, manuals, catalogs, or internal documents, with intelligent search and sourced answers.
  • Pre-quotes and client qualification: extracting information from incoming emails, forms, or documents, structuring the need, and generating an initial response.
  • Intelligent catalog: product search, variants, compatibilities, choice assistance, and exploitation of technical data.
  • Back-office AI Automation: document classification, data extraction, email generation, request summarization, API connection, and integration into your internal tools.
Use cases:
  • You waste time searching for information in PDFs, catalogs, technical datasheets, or procedures.
  • You manually process customer requests, quotes, emails, or incoming documents.
  • You have a complex product catalog with variants, compatibilities, or technical data that is difficult to exploit.
  • You have tested ChatGPT, Zapier, Make, or n8n, but you want a reliable, integrated, and maintainable business solution.
Technical Stack: OpenAI, Mistral, Anthropic, RAG, embeddings, pgvector, Python, Node.js, REST API, PostgreSQL, Docker, Nuxt 3, Vue.js, Medusa v2, Stripe.
