About Denis

**You lose hours every week on repetitive tasks**:
  • sorting emails,
  • entering invoices,
  • manually following up on leads,
  • answering the phone when you're already busy,
  • or any other task that comes up again and again.

This is exactly what I automate.

I design AI agents and automations that take over your business processes, from back office to switchboard:
  • lead qualification and enrichment,
  • document processing and extraction (invoices, quotes, photos),
  • automatic email sorting and drafting,
  • a voice agent that answers calls you can't take and schedules appointments,
  • chatbots and AI assistants connected to your tools.

Concrete results for my clients: several hours recovered each week, less manual data entry, and time for your teams to spend selling rather than copying data.

My advantage:I am a trained developer(SaaS applications in production).

I don't just plug in no-code tools.I use the right tools when they are sufficient, **and I code the critical parts myself when necessary**, for reliable automations that can handle production load. Specifically, AI never decides a figure for you: no agent inventing data for you.

You will find concrete demonstrations (video and before/after results) of what I can implement for you below.

Describe the task that wastes most of your time, and I'll tell you within 48 hours if and how I can automate it.

See you soon!

    AI Developer. Voice Agent for Artisans
    CIVIL ENGINEERING
    January 2026 - May 2026 (4 months)
    Paris, France
    Batilinkanswers the phone for the artisan when they can't pick up, typically when their hands are busy on a construction site. The agent takes the call, chats normally with the person, understands what they want (type of work, urgency, location, contact details), and schedules an appointment when justified.

    For an artisan, a missed call often means a client calling a competitor right after. Batilink's idea is to catch these calls and turn them into appointments, without the artisan having to put down their tools.

    The hardest part technically is real-time processing. The voice comes in, it needs to be transcribed, processed, and responded to vocally, and all this needs to be fast enough for the conversation to seem natural, not to mention people cutting in. The agent doesn't chat unnecessarily: it has a goal, to qualify and then schedule the appointment. It gathers information throughout the discussion and only confirms a time slot once it has everything, repeating the information to the caller to ensure accuracy.

    AI Developer. Financial Analysis and Personalized Advice
    BANKING AND INSURANCE
    July 2025 - December 2025 (5 months)
    Paris, France
    Vaultyrais an AI-powered budget management app. It retrieves transactions, categorizes them, and provides detailed analysis, including spending breakdowns, trends, and discrepancies, all presented in a gamified format. Based on this, it offers advice tailored to the person's situation, including a "tip of the day".

    From the start, I set a simple rule: the AI doesn't touch the numbers. All amounts, whether balances, category totals, or trends, are calculated by the code. The model is used for only two things: phrasing the advice based on an already quantified summary, and generating the gamification layer.
