About Thomas

Next.js / TypeScript Developer. I design, develop, and deploy modern web applications, with a clear specialty: integrating AI into production, not just toy demos.

My proof: I designed and launched mornn.me, a complete AI-personalized morning brief product, from the data pipeline to deployment, entirely on my own. Real source retrieval, LLM processing, user personalization, automated daily sending, all in production.

For my clients, I undertake two types of missions: React & Next.js front/full-stack development (team reinforcement or agency overflow), and adding AI features/automations to existing products (LLM API integration, content generation, automated pipelines). I'm also comfortable with deployment and infrastructure (Docker, CI/CD, Vercel): I deliver things that actually run, not just local code.

Based in Île-de-France, available remotely. Open to subcontracting for agencies and freelancers with overflow, as well as direct missions.

Experience

  • Mornn
    Full-Stack Developer & Designer - AI Product in Production
    March 2026 - Today (3 months)
    Design, development, and production deployment of a complete product, entirely on my own: mornn.me, an AI-personalized daily news brief.

    End-to-end pipeline: retrieving news via RSS feeds from real sources, processing and summarizing with LLM (Claude) anchored to the source content to avoid hallucination, user personalization (chosen topics, reading level per domain, daily agenda), then assembly and automated sending of a daily brief by email.

    Technical challenges overcome: information reliability (grounding on real sources rather than free generation, crucial for a news product); control of inference cost per brief; optional calendar integration within GDPR compliance (minimal reading, no long-term storage).

    Stack: Next.js, TypeScript, Tailwind, Vercel deployment, LLM API integration, automated ingestion and sending pipeline. Role: product design, development, production deployment, and operation, entirely solo.
