About Léon

I don't create generic chatbots. I design automated systems that do the heavy lifting for you: transforming your raw data into qualified leads, eliminating manual work, and generating revenue.

If your team wastes hours copy-pasting data or sorting leads: I automate it.

My Areas of Expertise:
  • End-to-end Automation: Python, robust APIs, and custom workflows.
  • Advanced API Integration: Production deployment (Anthropic models) for complex reasoning, classification, and extraction.
  • Intelligent Lead Pipelines: Automated discovery, enrichment, and predictive scoring.
  • Rapid Prototyping: Manual processes transformed into functional AI prototypes in 7 to 14 days.

Recent Production Projects:
  • Autonomous Lead Generation System: Integration of scraping tools, APIs, and information management tools (like Notion or Obsidian) to automatically extract, filter, and enrich high-value prospects.
  • Multi-Agent Automation Framework: Development of a scalable architecture (OpenClaw, Hermes) for parallel task execution.
  • AI Semantic Filtering: Design of semantic filtering systems to eliminate low-quality data before CRM integration.

Why Choose Me?
  • Business-Oriented: I don't write code for fun; I build to save you time and generate ROI.
  • Claude API Mastery: Advanced prompt caching, cost reduction, and context window management.
  • High Velocity: Concrete, reliable, and ready-to-use solutions delivered in days.

Availability:

Focus Summer 2026 (June–August). I'm taking on 1 to 3 short-term contracts (1 to 3 months) to fully immerse myself in your systems and deliver immediate results.

    Document Intelligence Engineer: Doc Intel Claude
    SOFTWARE PUBLISHING
    January 2026 - January 2026
    Paris, France
    Development of an intelligent document processing pipeline. The system takes PDF, DOCX, or TXT files as input and outputs structured data (JSON/CSV) with entities, dates, amounts, contracting parties, and risk flags.

    Key Features:
    - PDF (pypdf) and DOCX (python-docx) file parsing
    - Structured entity extraction via Claude API with strict Pydantic schema
    - Automatic validation: hallucination detection and routing for manual review
    - Asynchronous batch mode with limited concurrency (to avoid API quota exhaustion)
    - Optional REST interface via FastAPI
    - Technical stack documentation for handover

    Result:A folder of 50 PDFs becomes a structured CSV with invoices, dates, amounts, and risk flags in 2 minutes.

    SOFTWARE PUBLISHING
    October 2025 - October 2025

    Development of an AI agent for qualifying sales leads. The system ingests direct message conversations (Instagram, WhatsApp) in JSON format, sends each thread to the Claude API with a sales analyst prompt, and receives a structured score (0-100, intent, pain points, objections, next action).

    Key Features:
    - Automatic conversation scoring (accuracy >85%)
    - Purchase intent detection with false positive filtering
    - Push hottest leads to Telegram with a ready-to-read summary
    - SQLite cache to avoid redundant API calls
