About Thomas

AI in production without cloud dependency, autonomous robots deployed in the field. I transform your deeptech projects into delivered products.

WHAT I DO CONCRETELY:


→ Local & Sovereign AI
On-premise LLM deployment (Ollama, Llama, Mistral), RAG pipelines (MCP, LlamaIndex, ChromaDB), autonomous agents (LangChain, CrewAI, function calling). Your data stays with you. GDPR compliance, anticipation of AI Act.
Result: AI agent deployed in public places, -70% requests handled by staff, 24/7, zero cloud.

→ Robotics & Autonomous Systems
ROS2/Nav2 Expert (navigation stack rebuilt from scratch). Embedded perception (YOLO/TensorRT, 95% accuracy at 30fps on Jetson). Multi-sensor SLAM (<10cm). +10 robots deployed, 500+ missions, 3 commercial sites.

→ IoT & Edge Computing
From sensor to dashboard: LiDAR, stereo cameras, ESP32, Jetson, Raspberry Pi. Real-time protocols (WebSockets, MQTT, micro-ROS). Monitoring, actuators, touch HMI.

→ Full-Stack & Real-Time
React/Next.js, Python/FastAPI, React Native. 1000+ simultaneous WebSockets (<50ms). WebRTC video pipeline (80ms latency). Side project FlashTankArena.io: custom C++ engine, Rust gateway, 500 simultaneous players, 100% destructible procedural maps, AI bots by reinforcement learning.

→ Technical Direction
CTO as a Service: architecture audit, tech team structuring, product roadmap, go-to-market. Ex-CEO/CTO, €500k raised, team of 10.

PROOFS:


• 10 robots in production, 20,000+ km traveled, 2 years zero critical downtime
• On-premise AI agent: -70% staff workload
• FlashTankArena.io: 500 players/instance, scalable to 5000+, Discord community 500+
• €500k raised (Bpifrance, French Tech), 5 incubators (Station F, Village by CA)
• Featured on BFM Business TV

Experience

  • Tension Habit Tracker - Projet personnel
    Creator - HealthTech Mobile
    HEALTH AND WELLNESS
    December 2025 - December 2025
    Paris, France

    Personal project: mobile arterial health monitoring application, designed privacy-first with GDPR compliance and sovereign French hosting.


    DEVELOPMENT:

    • Cross-platform app (React Native, Expo, TypeScript) with a simplified patient interface, reminders, and PDF export for doctors.
    • Supabase/PostgreSQL backend with full data lifecycle management: consent, portability, right to erasure.

    ACQUISITION:

    • Landing page (Cloudflare Pages) that collected 2000+ emails in pre-launch.

    SECURITY & COMPLIANCE:

    • Hosting on sovereign HDS certified infrastructure (OVHcloud) — zero transfer outside the EU.
    • Privacy by Design architecture: end-to-end encryption, consent management, native GDPR compliance.

    Project suspended for strategic reasons. Demonstrates my ability to deliver a complete mobile app with strong regulatory constraints (health, personal data, sovereignty).

    Creator & Lead Engineer
    VIDEO GAMES AND ANIMATION
    November 2025 - Today (9 months)
    Paris, France

    Creator & Lead Engineer of a real-time multiplayer game built from scratch to push the boundaries of networking and performance.


    RESULTS:

    • 500 simultaneous players per instance, scalable infrastructure to 5000+
    • Perceived latency <50ms, multi-region (Europe, US, Asia)
    • Discord community 500+ members, tournaments and events
    • 200+ procedural skins via WebGL shaders

    ENGINE & CORE:

    • Fully custom C++ game engine (zero Unity/Unreal): collision, physics, rendering pipeline, memory optimization.
    • 100% destructible procedural maps generated by Perlin Noise and cellular automata — thousands of unique variations.
    • AI bots via Reinforcement Learning achieving superhuman level (throttled for gameplay).
    • Anti-cheat by design: server-side fog of war, data outside FOV is never sent to the client.

    INFRASTRUCTURE & NETWORK:

    • High-performance Rust gateway (tokio, axum) with zero-copy architecture and RTT <50ms.
    • Custom WebSocket binary protocol: client prediction, server reconciliation, delta compression.
    • Multi-region bare-metal servers with Cloudflare and auto-failover.

    PLATFORM:

    • Micro-transaction system (Stripe), multi-provider OAuth (Google, Discord, Reddit).
    • Custom analytics and admin dashboard (React, Supabase).
    • Reddit + Discord community with moderation bots and tournament system.

  • Confidentiel / Secteur Public
    Technical Lead - AI Agents & RAG
    DIGITAL AND IT
    June 2025 - August 2025 (2 months)
    Paris, France

    Technical lead on a project for autonomous AI agents deployed 100% locally for the public sector. Zero cloud dependency, full compliance.


    RESULTS:

    • -70% of routine requests handled by staff
    • 24/7 availability, zero cloud, 100% on-premise
    • Deployment in public places (parks, town halls, museums)

    AI AGENTS & RAG:

    • Local LLMs (Ollama, Llama 3, Mistral) for real-time on-site responses.
    • Full RAG pipeline: MCP Protocol, LlamaIndex, ChromaDB for contextual queries on knowledge base.
    • Multi-step autonomous agents (LangChain, LangGraph, CrewAI) for complex tasks.
    • Local voice recognition (Whisper.cpp), capable offline.
    • Function calling for API/DB interaction without human intervention.

    DOCUMENT PROCESSING:

    • PDF extraction (PyMuPDF, pdfplumber, Tesseract OCR).
    • NLP analysis (spaCy, sentence-transformers) and zero-shot classification for automatic email routing.
    • Extractive and abstractive automatic summarization, map-reduce for long documents.

    DEPLOYMENT & UX:

    • Intelligent human-in-the-loop escalation with confidence thresholds — auto-routing to human staff if AI is uncertain.
    • Admin dashboard (React) for non-technical staff: knowledge base updates without deployment.
    • Touchscreen kiosk interface (React, Electron), capable offline.
