About Alexandre

Senior Full-Stack Developer RAG & AI Agents, specializing in integrating agentic AI into core business products. I design and deploy web platforms where AI truly gets the job done: documentary pipelines, agents, RAG, heavy business task automation.

My playground: robust NestJS / Node.js backends, Next.js / React fronts, and AI systems that perform in production at scale.

Some concrete results:
  • At Alan, an agentic pipeline for processing health documents: automation increased from 64% to 89% on ~20,000 documents per week.
  • At La Capitainerie, complete development of a maritime recruitment platform with AI qualification of applications and documentary RAG: 25,000+ documents processed, 7,000 sailors, 300+ shipowners, ~€75,000 ARR.
  • At Modern (YC), an ITSM platform based on AI agents: workflow creation agent, a dozen integrations (Stripe, Google Workspace, Snowflake, Xero), redesign of the conversational support agent in a multi-source architecture (Slack, Teams, Email, WhatsApp).
What I build:
  • Backends NestJS, Node.js, Python, Go, PostgreSQL
  • Applications Next.js, React, TailwindCSS
  • AI Systems: agents, RAG, LLMs (OpenAI, Anthropic, Mistral, Gemini), documentary pipelines
  • Scalable Infrastructure: AWS, Cloudflare, OpenSearch, Redis, Docker, CI/CD
  • Payments: Stripe

12 years of experience, including Alan, Modern (YC), Unmind, LaCapitainerie.com, Boeing...

I transform complex business needs into clear products, and I move fast without sacrificing production quality.

Experience

  • Smartfire
    Senior Full-Stack Developer
    SOFTWARE PUBLISHING
    June 2026 - Today (2 months)
    Biarritz, France
    Complete redesign of a web application for temporary workers.

    To ensure and accelerate design integration, I implemented an agentic workflow that faithfully replicates Figma mockups. The agent connects to Figma via a local MCP server, reads frames, captures the visual rendering of components, and generates a precise implementation plan. Once the code is produced, other agents compare the result to the original Figma using a headless browser, in a loop until pixel-perfect correspondence.

    HEALTH AND WELLNESS
    January 2025 - February 2026 (1 year and 1 month)
    Paris, France
    At Alan, I worked on automating the processing of health documents, directly impacting operational costs and member reimbursement speed.
    I notably led the implementation of LLM-based automatic parsers to improve the extraction and validation of complex documents: social security statements and hospital bills.
    Key impacts:
    Improved parsing of social security statements, increasing the automation rate from 64% to 89% on a volume of approximately 20,000 documents per week.
    Created a hospital bill parser, for documents that were very time-consuming to process manually, with over 5 minutes of processing per document.
    Developed a control and correction interface for internal operators.
    Implemented the reprocessing request process, allowing members to request document reprocessing from the application.
    Implemented screen sharing in the video conferencing tool used for medical consultations.
    Main Stack: Python, OpenAI, Gemini, React, React Native, PostgreSQL, Sqlalchemy, Snowflake.
