About Roman

Architect-level AI Engineer | Knowledge Engineering | 12+ years of experience

I solve the data chaos problem for companies that need reliable AI Systems. I transform unstable prototypes into high-performance architectures, specializing in Knowledge Distillation, Agentic workflows, and cost-optimized production deployments.

What I deliver:
  • Production AI: From 2-week PoCs to scalable MLOps deployment.
  • Cost Efficiency: Specialized in reducing LLM inference costs (up to 50% reduction in recent projects).
  • Deep Domain Expertise: High-stakes industries including Pharma, Radiology (VLM), and Veterinary MedTech.
Core Technical Focus:
  • AI Agents: Complex orchestration using LangGraph and autonomous workflows.
  • Advanced RAG: Enterprise knowledge systems and intelligent corporate memory.
  • Voice & Audio: Clinical ASR and real-time speech-to-action solutions.
  • Computer Vision: Medical/Veterinary imaging analysis using VLMs.
Key Achievements:
  • Pharma: Designed an LLM retrieval platform that optimized costs by 45%.
  • Healthcare: Built an autonomous Multi-Agent ecosystem for clinical automation (LangGraph + ASR + CV).
Based in Paris. Available for remote or hybrid missions.

Experience

  • TN Systems
    Senior AI Engineer
    DIGITAL AND IT
    September 2025 - Today (9 months)
    Paris, France
    Autonomous Multi-Agent AI System for Veterinary Clinics


    Built a full-stack AI ecosystem integrating RAG, Multi-Agent orchestration, Streaming ASR, and Multimodal Computer Vision to fully automate clinical diagnosis and documentation workflows.

    Key Contributions:
    •Multi-Agent Architecture: Designed orchestration logic (LangGraph) coordinating specialised agents (ASR, RAG, Radiology, Reasoning) into a unified diagnostic system.
    •Streaming ASR: Engineered a high-performance real-time ASR pipeline (fine-tuned model) to transcribe vet-client dialogues automatically.
    •CV/Multimodal (Radiology): Implemented X-ray analysis module based on self-supervised JEPA architecture — generates structured image descriptions and differential diagnoses.
    •MLOps & Performance: Optimised inference services including a Rust-based pipeline for minimal latency in real-time critical functions.
    •AI-Native Development: Leveraged Cursor and Claude Code to maximise engineering velocity across the full stack.

    Results:
    •↓ 50% appointment documentation time → doubled clinic throughput
    •↓ Diagnostic and documentation errors via structured reasoning and validated medical templates

    Project 1: LLM-Powered Knowledge Retrieval Platform (Pharma)

    • Architected and deployed a RAG-based knowledge retrieval system fine-tuned for pharmaceutical data, integrated with internal corporate platforms.
    • Designed full lifecycle pipeline: data ingestion, embedding storage, domain-specific fine-tuning, and cloud inference optimisation.
    • Implemented AI-driven report generation module powered by autonomous agents.

    Results: ↓ 70% manual preprocessing · ↓ 40% inference costs · Automated end-to-end generation of internal training materials.

    Project 2: AI Training Platform for Medical Representatives (LLM Simulation)

    • Engineered real-time interaction loop combining LLM-driven objection handling with lip-sync avatars.
    • Built LLM-powered agents generating dynamic, context-aware medical dialogues tailored to specific pharmaceutical products.
    • Delivered customisable scenario templates (therapeutic areas, scripts, complexity levels).

    Results: ↓ 80% manual training preparation · ↓ 50% cloud inference costs via quantization and caching · Automated scenario creation and reporting.

    Tech Stack: Python, LangChain, LangGraph, LlamaIndex, HuggingFace, Ollama, AWS, Kubernetes, Docker, FastAPI, CI/CD
