Back to original languageAbout Sven
AI Engineer graduated from IMT Atlantique, I support product, data, and tech teams in designing robust GenAI solutions: LLM agents, RAG pipelines, business assistants, automated document generation, NLP classification, LLMOps evaluation and observability.
I primarily focus on transforming business needs into concrete AI applications: architecture, model selection, LLM orchestration, FastAPI backend, data integration, tool setup, testing, evaluation, monitoring, and deployment.
My recent experiences include:
- developing LLM pipelines for medical document generation with LangChain, LangSmith, FastAPI, SQLAlchemy, PostgreSQL, Docker, and Kubernetes;
- designing a medical conversational agent with tools and data sourcing;
- fine-tuning NLP models for medical data pseudonymization;
- building Komainu, an AI platform for requirements ↔ tests traceability based on LangGraph, hybrid RAG, LLM agents, FastAPI, Celery, PostgreSQL, Langfuse, MCP, Railway, Vercel, and Supabase;
- developing an advanced portfolio project, NBA AI Consultant, combining Mixture of Agents, MCP tools, temporal RAG, observability, cost/latency evaluation dashboard, and cloud deployment.
I can help you with:
- creating or auditing RAG pipelines;
- designing LLM agents connected to your internal tools;
- industrializing LangChain / LangGraph prototypes;
- setting up evaluation, traces, costs, latency, and LLMOps monitoring;
- developing AI APIs in FastAPI;
- reducing hallucinations via grounding, citations, and testing.
My goal: deliver useful, reliable, measurable, and maintainable AI systems adapted to your business context.
