AI, Data & Big Data Engineering
I design intelligent digital products — AI agents, RAG copilots, web and mobile apps — from the data all the way to the user.

Profile
AI & Data engineer: I design the intelligence of the product and ship it all the way to the app.
Big Data & AI Engineer
NVIDIA Certification — AI & Generative AI
I build end-to-end AI agent systems — assisted diagnostics, RAG copilots, voice and multimodal pipelines — shipped as complete web and mobile applications, backed by the Big Data & BI layer behind them.
What I do
From management apps to websites, from business software to intelligent agents: tailor-made digital solutions, with artificial intelligence at the heart of your projects.
Chatbots & assistants · Autonomous AI agents · Custom AI solutions
Point-of-sale (POS) apps · Invoicing software · Back office & dashboards
Mobile apps (iOS & Android) · QR code solutions
Showcase websites · Dynamic websites · Custom web applications
Digitalisation projects · Automation & integrations
Selected work
From AI agent systems to data platforms — a selection of projects carried end to end.
An integrated platform built on 8 years of a car workshop's real history — management, a diagnostic copilot, predictive maintenance and customer relations.
An intelligent digital system — website, mobile app and AI chatbot — unifying 34,000+ reservations scattered across 186 scanned documents.
Forecasting sales and waste for every product in a store, and recommending the right quantities to order.
An assistant that answers marketing strategy questions from a corpus of course material — and says so plainly when it doesn't know.
An agent system that plans, drafts and publishes content, from brief to live.
A clinical agent that estimates a clinician's cognitive load from their voice, and adapts its recommendations to their state.

Technical notes, project retrospectives and thoughts on building AI systems.
While building Sentinelle's voice copilot, the real latency problem wasn't where I expected it — and the fix cost nothing in audio quality.
Why most RAG pipelines hallucinate out of overconfidence, and three concrete levers to make an agent recognise the limits of what it actually found.
A linear chain is enough for a lot of LLM use cases. Here's the concrete signal that made me move some projects to LangGraph — and the ones where a simple chain was the right call.
