Freelance - Toulouse, France

Web and mobile architect. 15 years of experience. I help my clients define, design and build their technical solutions.

About

Web developer for 15 years. I've worked in consulting firms, startups, and I'm now freelancing from Toulouse, France. As a web and mobile architect, I help my clients define their solution's architecture, advise them on their technical choices, and contribute directly to their projects.

I've built several mobile apps and SaaS platforms end-to-end (NodeJS backend, NuxtJS frontend, PostgreSQL, CI/CD deployment on PaaS, payment APIs, email/SMS, external authentication...) across various domains (marketing, training, travel, marine aquariums).

I spent three years road-tripping across the Americas with my family and now live in France with my three children. Beyond development, I enjoy 3D modeling and printing, and building small electronics projects.

Background

15 years of professional web development
Former CTO of a SaaS startup (acquired)
3 years road-tripping across the Americas with my family
Freelancing from Toulouse, available for remote work

I can help you

I'm actively looking for a position or mission related to my skills and interests. If you need help with mobile app development, SaaS, or AI-related applications, feel free to reach out.

I integrate LLM APIs into web tools daily: OpenAI, Claude, Gemini, Mistral, Groq, Llama. From function calling to autonomous agent orchestration, including RAG and conversational workflows. If you have an AI-related need, I'd love to help.
