Hippolyte Durand

Data & AI Apprentice @ SNCF • ECE Paris (Ingénieur cycle)

I design pragmatic AI systems, from retrieval-augmented pipelines to autonomous agents that can speak SQL. Previously at Tetra7, I implemented a lightweight Model Context Protocol (MCP) setup: an MCP server exposing tools, resources, and prompts to the model client. I paired it with RAG (embeddings + vector search), a schema-aware SQL agent for safe, read-only queries, and a production-grade document classifier. I’m currently an apprentice at SNCF Voyageurs and I’m seeking a 3-month internship (May–July 2026).

Available May–July 2026 Apprenticeship @ SNCF MCP • RAG • SQL Agent • Classifier

What can I do ?

Model Context Protocol (MCP) orchestration + RAG

Built an MCP server that advertises tools, resources, and prompts to an MCP client with capabilities. Implemented tool discovery. Integrated a RAG layer (embeddings + vector index) to serve contextual resources, enabling the agent to select and invoke the right tool per request.

Laravel + Livewire Dashboards & APIs

Built clean Laravel backends with RESTful endpoints, request validation, policies, and expressive Eloquent relations. Shipped Livewire dashboards with server-driven interactions, eager-loaded metrics, and background queues (Redis) for long-running jobs. Added caching and structured logs to keep p95 fast and debugging predictable.

Document Classifier

Production classifier for industry documents with robust PDF/text parsing, field normalization, and calibrated confidence scores. Added an evaluation harness (stratified sets, error breakdowns) and simple thresholding to balance precision/recall. Exposed the model behind an HTTP endpoint with idempotent requests and audit trails for reliable ops.
