Back to original languageAbout Kevin
With over 10 years of experience in web development, I now work as a senior Full-Stack developer and freelance CTO on highly complex technical projects. I have designed and managed critical business applications: multi-tenant SaaS platforms, fleet management systems, document management tools, and B2B automation solutions. I handle the entire cycle: technical scoping, architecture choices, development, infrastructure, and deployment. Since 2023, I have specialized in advanced AI integration: autonomous agents, RAG pipelines, vector memory (Qdrant), business automation (n8n), and local LLM deployment (Ollama). I build sovereign and tailor-made AI solutions, designed for the real constraints of French companies: performance, data confidentiality, and independence from cloud infrastructures. I support my clients from defining their needs to the final product, with a results-oriented approach: clear deliverables, complete documentation, and future-proof architectures. Main stack: Laravel, React/Inertia, PostgreSQL, n8n, Filament, Qdrant, Ollama. Based in Bourgogne-Franche-Comté, I work fully remotely across France.

The platform is based on a modular plugin architecture, allowing features to be enabled or disabled as needed without burdening the core application.

- ATOMIKAGENCYChatbyIA - Simplified AI ChatbotDIGITAL AND ITJanuary 2026 - April 2026 (3 months)Development of ChatByIA, a multi-tenant SaaS platform for deploying custom AI chatbots, designed to enable agencies and businesses to offer conversational assistants to their clients under white-label. Each tenant has its own isolated space, AI configuration, data sources, and a widget embeddable on any website via a lightweight script tag. The core of the product relies on a complete RAG pipeline: document ingestion (PDF, Word, text, URLs), chunking and vectorization, storage in Qdrant, and generation of contextualized responses via LLM. The JS widget manages initialization, user session, conversation history, and escalation to a human agent when needed. Architecture designed for white-label: complete interface customization (colors, logo, assistant tone), billing tier management per tenant via Stripe, and an administrator dashboard using Filament for overall account supervision. Deployable on private infrastructure for clients wishing to maintain control over their data. Stack: Laravel, React, Inertia.js, PostgreSQL, Qdrant, Stripe.
